Results

Some people regret not studying, but no one regrets studying too much.

#1. They downloaded and ran an application via the Internet that looked useful, and now their computer won’t run at all. What type of malware is this?

〇:Trojan Horse

A Trojan horse is a seemingly harmless piece of malware that is contagious. Have you ever downloaded a nasty image and suddenly your computer stopped working?

 

×:Spyware

Spyware is malware that looks harmless when it does its evil. It secretly takes information from your computer to the outside.

 

×:Virus

Viruses are malware that can spread without user intervention and attach itself to other programs. It looks harmless but does not match in that it downloads applications.

 

×:Data diddlers

A data diddler is malware that gradually changes data over time.

#2. What role does the Internet Architecture Committee play with respect to technology and ethics?

〇:To issue ethics-related statements on the use of the Internet.

The Internet Architecture Board (IAB) is the coordinating committee for the design, engineering, and management of the Internet. It is responsible for monitoring and appealing Internet Engineering Task Force (IETF) activities, the Internet standards process, and the architecture of Request for Comments (RFC) editors. The IAB issues ethics-related statements on the use of the Internet. The Internet is a resource that depends on availability and accessibility and is considered useful to a wide range of people. Primarily, irresponsible behavior on the Internet may threaten its existence or adversely affect others.

 

×:Develop guidelines for criminal sentencing.

The IAB is incorrect because it has nothing to do with the Federal Court Guidelines, which are the rules judges use in determining the appropriate punitive sentence for certain felonies or misdemeanors committed by individuals or businesses. The Guidelines serve as the uniform sentencing policy for entities committing felonies and/or gross misdemeanors in the U.S. federal court system.

 

×:Edit RFC.

The Internet Architecture Board is responsible for editing RFCs (Request for Comments), which is incorrect because this task is not ethics-related. This answer is a distraction.

 

×:Maintain the Ten Commandments of Computer Ethics.

This is incorrect because the Institute for Computer Ethics, not the IAB, develops and maintains the Ten Commandments of Computer Ethics. The Institute for Computer Ethics is a non-profit organization that works to advance technology through ethical means.

#3. What type of disaster is an earthquake classified as?

Disasters are classified by cause into natural, human, and environmental categories. Natural disasters are natural, human errors are human, and facilities and equipment are environmental.

#4. There are two main design philosophies for systems that implement access control: distributed or integrated. Which are the advantages of distributed access control?

〇:The ability to control access close to the resource.

Central access control has various advantages such as uniform rules and reduced operational burden. Distributed access control allows access control in close proximity to resources, thus protecting resources independently.

 

×:It should be possible to design a comprehensive

Distributed access control is not a comprehensive design because the authentication and authorization functions are distributed.

 

×:Relatively low cost.

Whether or not costs can be kept down cannot be determined by this design concept alone.

 

×:Logs from various devices make it easier to understand the current status.

Both central access control and distributed access control can acquire logs from various devices.

#5. RAID systems are available in a variety of methods that provide redundancy and performance. Which ones write data divided across multiple drives?

〇:Striping

RAID redundant arrays is a technology used for redundancy and performance. It combines multiple physical disks and aggregates them into a logical array; RAID appears as a single drive to applications and other devices. With striping, data is written to all drives. With this activity, data is split and written to multiple drives. Since multiple heads are reading and writing data at the same time, write and read performance is greatly improved.

 

×:Parity

Parity is used to reconstruct corrupted data.

 

×:Mirroring

Writing data to two drives at once is called mirroring.

 

×:Hot Swap

Hot swap refers to a type of disk found on most RAID systems. A RAID system with hot-swap disks allows the drives to be swapped out while the system is running. When a drive is swapped out or added, parity data is used to rebuild the data on the new disk that was just added.

#6. Which is the most correct use of a captive portal?

A captive portal is a mechanism that restricts communication with the outside world until user authentication, user registration, and user consent are performed when a terminal connects to the network.

#7. In computer programming, coupling and condensing degrees are used. Which of the following is the preferred combination of coupling and condensing degree?

It is a good thing for a module to have low coupling and high condensibility. The higher the degree of condensation, the easier it is to update and modify, and it does not affect other modules with which it interacts. This also means that modules are easier to reuse and maintain. Coupling degree is a measure of the amount of interaction a single module requires to perform its task. If a module’s coupling is low, it means that the module does not need to communicate with many other modules to perform its job. It is easier to understand and reuse than a module that depends on many other modules to perform its tasks. It will also be easier to modify modules without affecting the many modules around them. Therefore, the correct answer is “low-coupling, high-cohesion”.

#8. Which of the following is true about digital forensics?

〇:It encompasses network and code analysis and is sometimes referred to as electronic data discovery.

Forensics is the analysis of electronic data that may have been affected by technology, authentication, and criminal activity requiring special techniques to ensure the preservation of information. It comes together of computer science, information technology and engineering in the legal system. When discussing digital forensics with others, it may be described as computer forensics, network forensics, electronic data discovery, cyber forensics, etc.

 

×:The study of computer technology.

Digital forensics is incorrect because it involves information technology rather than research. It encompasses the study of information technology, but also includes collecting and protecting evidence and working within specific legal systems.

 

×:A set of hardware-specific processes that must be followed in order for evidence to be admissible in court.

Digital forensics is incorrect because it does not refer to hardware or software. It is a set of specific processes related to computer usage, examination of residual data, technical analysis and description of technical characteristics of the data, and reconstruction of the authentication of data by computer usage that must be followed for the evidence to be admissible in court.

 

×:Before an incident occurs, digital forensics roles and responsibilities should be assigned to network administrators.

This is wrong because digital forensics must be done by people with the proper training and skill set who could not possibly be administrators or network administrators. Digital forensics can be fragile and must have been worked on properly. If someone reboots an attacked system or inspects various files, it could corrupt and change executable evidence, key file timestamps, and erase any footprints the criminal may have left behind.

#9. One approach to fighting spam mail is to use the Sender Policy Framework, an email validation system. What type of system implements this functionality and receives and responds to requests?

Sender Policy Framework (SPF) is an email verification system that detects email spoofing and prevents spam and malicious email. Attackers typically spoof e-mail addresses to make recipients believe that the messages come from a known and trusted source. SPF allows network administrators to specify which hosts can send mail from a particular domain by implementing SPF records in the Domain Name System (DNS). The e-mail server is configured to check with the DNS server to ensure that e-mail sent from a particular domain was sent from an IP address authorized by the administrator of the sending domain.

#10. Brian has been asked to create a virtual directory for the company’s new identity management system. Which of the following best describes the virtual directory?

〇:Virtual Container for Data from Multiple Sources
Network directories are containers for users and network resources. Because one directory does not contain all the users and resources in an enterprise, a collection of directories must be used. A virtual directory collects the necessary information used from sources scattered throughout the network and stores it in a central virtual directory (virtual container). This provides a unified view of digital identity information for all users across the enterprise. The virtual directory is regularly synchronized with all identity stores (individual network directories) to ensure that up-to-date information is being used by all applications and identity management components in the enterprise.

 

×:Metadirectory

Virtual directories are similar to metadirectories, but incorrect because metadirectories work with one directory and virtual directories work with multiple data sources. When the Identity Management component calls the virtual directory, it can scan different directories across the enterprise, but the metadirectory only has the ability to scan one directory it is associated with.

 

×:User attribute information stored in the HR database

Incorrect because it describes an identity store. Much of the information stored in identity management directories is scattered throughout the enterprise. User attribute information (employee status, job description, department, etc.) is typically stored in the HR database. Authentication information can be stored in a Kerberos server, and resource-oriented authentication information can be stored in the domain controller’s Active Directory. These are commonly referred to as identity stores and are located elsewhere on the network. Many identity management products use virtual directories to call up the data in these identity stores.

 

×:Services that allow administrators to configure and manage the way identities are

This is incorrect because it describes a directory service. Directory services allow administrators to configure and manage how identification, authentication, permissions, and access control are performed within a network. It uses namespaces to manage objects in the directory and enforces security policies configured by performing access control and identity management functions.

#11. Which of the following is not an acronym for CIA Triad?

CIA stands for Confidentiality, Integrity, and Availability.

#12. Which of the following should NOT be done in proper hardware disposal procedures?

Deleting a file is physically recoverable. Shredding, demagnetizing, and overwriting are all methods that render the file physically unrecoverable.

#13. Which of the following are possible standards used for credit card payments?

〇:PCI DSS

PCI DSS (Payment Card Industry Data Security Standard) is a framework to avoid personal information leakage when making electronic payments. Therefore, the correct answer is “PCI DSS.

By the way, if you were to ask, “Which of the following are possible?” I am tempted to argue that other frameworks may be used as well. However, in the CISSP exam, you may have to choose “the most plausible” option in some cases. Therefore, we have used this phrase.

 

×:HITECH

The Health Information Technology for Economic and Clinical Health Act (HITECH) is an enhanced version of HIPPA that applies not only to data management but also to health care business associates.

 

×:OCTAVE

OCTAVE is one of the risk assessment frameworks introduced in CERT.

 

×:COBIT

COBIT is a framework for measuring the maturity of a company’s IT governance. It was proposed by the Information Systems Control Association of America (ISACA) and the IT Governance Institute (ITGI).

#14. What is code review?

〇:A review by another coder after the coder has completed coding.

A static code review is a review performed by another engineer to mitigate points that were not apparent to the author. Thus, the correct answer is “Reviewed by another coder after the coder’s coding is complete.” will be.

 

×:To allow coders to see each other’s coding and work in parallel.

Extreme programming (XP, extreme programming) is a flexible method of developing a program while discussing it in pairs. It is not code review.

 

×:Ensuring that proper transaction processing is applied before check-in.

This is a statement about database commitment.

 

×:Ensuring that the appropriate questions and answers exist.

The presence of appropriate question and answer may be part of what is performed during the code review, but it is not a description of the code review itself.

#15. Follow the guidelines to enable secure remote management. Which of the following is NOT one of those guidelines?

〇:Telnet must be used to send commands and data.

Telnet sends all data, including administrator credentials, in plain text and should not be allowed for remote administration. This type of communication should be via a more secure protocol, such as SSH.

 

×:Only a small number of administrators should be allowed to perform remote functions.

Wrong, as it is true that only a few administrators should be able to perform remote functions. This minimizes the risk to the network.

 

×:Critical systems should be managed locally, not remotely.

Wrong because it is true that critical systems need to be managed locally, not remotely. It is safer to send management commands on an internal private network than over a public network.

 

×:Strong authentication is required.

Wrong because it is true that strong authentication is required for any management activity. Anything weaker than strong authentication, such as a password, is easy for an attacker to break in and gain administrative access.

#16. Jill has established a company-wide sales program that requires user groups with different privileges in accessing information on a centralized database. What database should the security manager secure?

〇:Increasing database security controls and providing more granularity.

The best approach to protecting the database in this situation would be to increase controls and assign detailed permissions. These measures would ensure that users cannot abuse their permissions and that the confidentiality of the information is maintained. The granularity of permissions would give network administrators and security professionals additional control over the resources they are charged with protecting, and the granular level would allow them to give individuals just the exact level of access they need.

 

×:Implement an access control where each user’s privileges are displayed each time they access the database.

Implementing an access control that displays each user’s permissions is incorrect because they are an example of one control each time they access the database. This is not the overall way of dealing with user access to a database full of information. This may be an example of better database security control, but it needs to be limited to the right places.

 

×:Change the classification label of the database to a higher security status.

The classification level of the information in the database should previously be determined based on its level of confidentiality, integrity, and availability. This option implies that a higher level of authorization should be given, but there is no indication in the question text that the security level is inappropriate.

 

×:Reduce security. Allow all users to access information as needed.

The answer to reduce security is incorrect.

#17. Brad wants to ban the use of instant messaging (IM) on corporate networks. Which of the following should NOT be included in his presentation?

〇:The use of IM can be stopped by simply blocking certain ports on the network firewall.

Instant messaging (IM) allows people to communicate with each other via real-time and personal chat room types. These technologies will have the ability to transfer files. Users install an IM client and are assigned a unique identifier; they provide this unique identifier to anyone they wish to communicate with via IM. ineffective.

Another way to answer the question is to say that the question itself confirms our understanding of security, and then we can lay down the assumption that “should not be included in the presentation” means that we should not say anything that will later be held liable. There will be far more events that indicate that there is a possibility than events that say there is no possibility at all.

 

×:Sensitive data and files can be transferred from system to system via IM.

This is incorrect because in addition to text messages, instant messaging allows files to be transferred from system to system. These files could contain sensitive information, putting the company at business or legal risk. And sharing files via IM will use that much network bandwidth and impact network performance.

 

×:Users can be subjected to attacks posing as legitimate senders from malware containing information.

Incorrect because it is true. Due to lack of strong authentication, accounts can be falsified because there is to accept information from malicious users of the legitimate sender, not the receiver. There will also be numerous buffer overflows and malformed packet attacks that have been successful with different IM clients.

 

×:A security policy is needed specifying IM usage limits.

This is incorrect because his presentation should include the need for a security policy specifying IM usage restrictions. This is only one of several best practices to protect the environment from IM-related security breaches. Other best practices include upgrading IM software to a more secure version that configures the firewall to block IM traffic, implementing a corporate IM server so that only internal employees communicate within the organization’s network, and implementing an integrated Includes implementing an antivirus/firewall product.

#18. Which of the following cannot be said to be privacy information under the concept of information security?

Student numbers, which are left to the control of each school, cannot be considered privacy information because they are not sufficient information to identify an individual.

#19. Lisa learned that most databases implement concurrency control. What is concurrency? And why do we need to control it?

〇:A process that is running concurrently. If not properly controlled, the integrity of the database can be adversely affected.

Databases are used simultaneously by many different applications and many users interact with them at once. Concurrency means that different processes (applications and users) are accessing the database at the same time. If this is not properly controlled, processes can overwrite each other’s data or cause deadlock situations. The worst consequence of concurrency problems is poor integrity of the data held in the database. Database integrity is provided by concurrency protection mechanisms; one concurrency control is locking, which prevents users from accessing or modifying data being used by other users.

 

×:Processes running at different levels. If not properly controlled, they can adversely affect the integrity of the database.

Concurrency is incorrect because it refers to processes running at the same time, not at different levels. Concurrency problems occur when the database can be accessed simultaneously by different users or applications. If controls are not in place, two users can access and modify the same data at the same time, which can be detrimental to a dynamic environment.

 

×:The process of inferring new information from a review of accessible data. Inference attacks may occur.

The ability to infer new information from reviewing accessible data occurs when subjects at lower security levels indirectly infer data at higher levels. This can lead to an inference attack, but is not related to concurrency.

 

×:Storing data in multiple locations in the database. If not properly controlled, it can negatively impact database integrity.

Storing data in multiple locations is incorrect because there is no concurrency issue. Concurrency becomes an issue when two subjects or applications are trying to modify the same data at the same time.

#20. Which of the following technologies can be used to logically combine physically disparate groups of systems and help provide immunity to failure while also helping with scalability?

〇:Clustering

Clustering is a fault-tolerant server technology in which servers are redundantly analogous. A server cluster is a group of servers that can be logically interpreted by users as one server and managed as a single logical system. Clustering provides availability and scalability. It helps to provide immunity to this group, physically distinct systems and failure and improved performance.

The problem statement is phrased in a difficult sentence. It would be difficult to derive the exact specific words from the phrase “logically coupled with a physically distinct group of systems.” In such questions, it is useful to use a process of elimination to derive options from the words that would be the point of the question. From the latter part, “technology that helps provide immunity to failure while also helping with scalability,” we can see that it is something that is both fault-tolerant and scalable. Fault tolerance alone does not narrow down the choices, but in terms of scalability features, clustering falls into this category. Therefore, the correct answer is “clustering.

 

×:Disk dupe

There is no such term. When presented with a seemingly incomprehensible sentence, you may consider the possibility that it is a word you probably do not know, given the time limit.

 

×:RAID

RAID (Redundant Array of Independent/Inexpensive Disks) is a technology for operating multiple hard disks as a single hard disk. It has a mechanism to improve physical redundancy by how the data to be recorded is written to the hard disks. This is not a technology system that ensures scalability.

 

×:Virtualization

Virtualization is a technology that makes it appear as if multiple operating systems are running on the system. Or, it is an environment that enables the construction of a real environment through simulation-like operations surrounding them. While virtualized environments allow for the construction of environments that provide fault tolerance and scalability, they do not match the operation of logically combining them with physically different groups of systems.

#21. Would it make sense to measure marketing metrics from a security perspective?

〇:Yes. The same goal should be held because there is security in achieving corporate goals.

There are KPIs and other marketin indicators to achieve organizational goals. Developing a security function in the organization also exists to achieve these goals.

 

×:Yes. Marketing in the security industry is allowed to be risk-off.

By “marketing in the security industry,” I do not mean aligning the security function within the organization.

 

×:No. The division of labor should be strictly enforced and left to specialists.

While the division of labor in an organization is certainly important, all members of the organization need to be security conscious.

 

×:No. Security has nothing to do with confidential information that would be an executive decision.

Security should be addressed by the entire organization. It is not irrelevant.

#22. When penetration testers are doing white box testing, how much do they know about the target?

In white box software testing, the tester has full knowledge of the program’s source code, data structures, variables, etc.

#23. Which is the appropriate period of time to use maintenance hooks?

〇:Only during code development.

Maintenance hoc refers to functions and tools that are temporarily used by the developer for testing purposes. In fact, in system development, tools are provided to assist in confirming that individual functions are working properly. However, if maintenance hocks are left in the production environment, they may be used by attackers and must be removed.

 

×:Maintenance hooks should not be used.

The use of maintenance hooks can make the work more efficient.

 

×:When you want to make the software available to administrators in a simplified manner.

In some cases, attackers can exploit tools that were supposed to be available only to administrators.

 

×:When you want users to be able to use the software in a simplified manner.

After the actual release of the software, maintenance hooks are not made available to users.

#24. There are several calculation methods used to evaluate the value of an asset. Which of the following is NOT used to determine the value of an asset?

〇:Level of insurance required to cover assets.

This question is about choosing what is not used. There are several ways to calculate asset value (AV, Asset Value): the market approach, which refers to similar assets in the market, the income approach, which measures it by the profit it will earn in the future, and the cost approach, which measures it by the cost spent on the asset. The level of insurance needed to cover an asset is a decision made after identifying the asset value and conducting an appropriate risk analysis, allowing the organization to more easily determine the level of insurance coverage to purchase for that asset. Therefore, the correct answer is “level of insurance required to cover the asset”.

 

×:Value of the asset in the external market.

The technique of referring to similar assets in the market is known as the market approach.

 

×:Initial costs and outlay for purchasing, licensing, and supporting the asset.

The method of measuring by the cost spent on an asset is known as the cost approach.

 

×:The value of the asset to the organization’s production operations.

The method of measuring by the profit that will be earned in the future is known as the revenue approach.

#25. Mandy needs to generate keys for 260 employees using the company’s asymmetric algorithm. How many keys will be needed?

In an asymmetric algorithm, every user must have at least one key pair (private and public key). In a public key system, each entity has a separate key. The formula for determining the number of keys needed in this environment is by the number N × 2, where N is the number of people to distribute. In other words, 260 x 2 = 520. Therefore, the correct answer is 520.

#26. You have been instructed to report to the Board of Directors with a vendor-neutral enterprise architecture framework that will help reduce fragmentation due to inconsistencies between IT and business processes. Which of the following frameworks should you propose?

〇:TOGAF

The Open Group Architecture Framework (TOGAF) is a vendor-independent platform for the development and implementation of enterprise architecture. It focuses on the effective management of enterprise data using metamodels and service-oriented architectures (SOA). Proficient implementations of TOGAF aim to reduce fragmentation caused by inconsistencies between traditional IT systems and actual business processes. It also coordinates new changes and functionality so that new changes can be easily integrated into the enterprise platform.

 

×:Department of Defense Architecture Framework (DoDAF)

In accordance with the guidelines for the organization of the enterprise architecture of the U.S. Department of Defense systems, this is incorrect. It is also suitable for large, complex integrated systems in the military, civilian, and public sectors.

 

×:Capability Maturity Model Integration (CMMI) during software development.

It is inappropriate because it is a framework for the purpose of designing and further improving software. CMMI provides a standard for software development processes that can measure the maturity of the development process.

 

×:ISO/IEC 42010

Incorrect because it consists of recommended practices to simplify the design and conception of software-intensive system architectures. This standard provides a kind of language (terminology) to describe the different components of software architecture and how to integrate it into the development life cycle.

#27. Which of the following is not an official risk methodology created for the purpose of analyzing security risks?

〇:AS / NZS 4360

AS / NZS 4360 can be used for security risk analysis, but it was not created for that purpose. It takes a much broader approach to risk management than other risk assessment methods, such as NIST or OCTAVE, which focus on IT threats and information security risks. AS / NZS 4360 can be used to understand a firm’s financial, capital, personnel safety, and business decision-making risks.

 

×:FAP

Incorrect as there is no formal FAP risk analysis methodology.

 

×:OCTAVE

Image B is incorrect because it focuses on IT threats and information security risks. OCTAVE is intended for use in situations that manage and direct information security risk assessments within an organization. Employees of an organization are empowered to determine the best way to assess security.

 

×:NIST SP 800-30

Wrong because it is specific to IT threats and how they relate to information threats. Focus is primarily on systems. Data is collected from network and security practices assessments and from people within the organization. Data is used as input values for the risk analysis steps outlined in the 800-30 document.

#28. Which of the following attacks are related to availability?

〇:DDoS attacks

Availability is one of the properties of the CIA triad that indicates service continuity. An attack that threatens the continuity of service corresponds to a DDoS attack that sends a large number of requests and causes a service outage. Therefore, the correct answer is “DDoS attack”.

 

×: Wheeling

Whaling is a spear-phishing attack that targets a socially recognized person or organization.

 

×: TOC/TOU

TOC/TOU is a software bug that occurs when the system is modified between the time a condition is checked and the time the results of that check are used. In many cases, the attack replaces one file with another between looking for the file and reading the file.

 

×: DRAM

RAM (Random Access Memory) is memory used for CPU and screen displays, etc. DRAM is RAM that is only stored for short periods of time and requires periodic refreshing.

#29. In United States, federal agencies must comply with the Federal Information Processing Standard 201-2 to ensure which of the following?

〇:That the identity of the public official has been properly verified.

FIPS 201-2 establishes U.S. government standards for personal identity verification (PIV) and gives various requirements for assurance. Access to restricted information by government employees and contracting agents depends on their level of clearance and need to know it, but first the government must assure the individual that they are who they say they are.

 

×:That government employees are properly cleared for the work to which they are assigned.

Government employees must be properly cleared for the information to which they have been granted access, and therefore true identification must be available for review and verification prior to such access.

 

×:Government employees are only allowed access to data at their clearance level.

This is wrong because government employees only need to get acquainted and have access to the information they need to access. But again, this must be based on a clear level of assurance that the clearance they possess is valid.

 

×:That the data to which public officials have access is properly classified.

This is incorrect because the classification of data is not directly related to the validation of personal information.

#30. Mary is creating malicious code to steal user cookies by modifying client-side JavaScript. Which type of cross-site scripting vulnerability does she exploit?

〇:DOM-based

Mary exploits a cross-site scripting (XSS) vulnerability called Document Object Model (DOM) Local Cross-Site Scripting.The DOM is a standard structural layout for representing HTML and XML documents in a browser. In such attacks, components of the document such as form fields and cookies can be referenced via JavaScript. The attacker uses the DOM environment to modify the client-side JavaScript. The result is to cause the victim’s browser to execute malicious JavaScript code. The most effective way to prevent these attacks is to disable scripting support in the browser.

 

×:Secondary

Secondary, or persistent XSS vulnerabilities are incorrect because they target websites that populate databases or data stored elsewhere, such as forums or message boards.

 

×:Persistent

Persistent XSS vulnerability is incorrect because it is simply another name for a secondary vulnerability.

 

×:Non-Persistent

A non-persistent XSS vulnerability, called a reflection vulnerability, is incorrect because it uses a malicious script to open a programmed URL in order to steal sensitive information from someone who holds cookies, etc. The principle behind this attack lies in the lack of proper input or output validation on dynamic websites.

#31. Sally has performed software analysis against her company’s proprietary applications. She has found that it is possible to force an authentication step to take place before the attacker has successfully completed the authentication procedure. What could be the cause?

〇:Conflict condition

A race condition is present when a process performs a task on a shared resource and the sequence could be in the wrong order. 2 or more processes can have a race condition if they use a shared resource, like data in a variable. It is important that processes perform their functions in the correct sequence.

 

×:Backdoors

Backdoors are incorrect because they are “listening” services on certain ports. Backdoors are implemented by attackers to allow easy access to the system without authenticating as a normal system user.

 

×:Maintenance Hooks

Maintenance hooks are specific software codes that allow easy and unauthorized access to sensitive parts of a software product. Software programmers use maintenance hooks to allow them to get quick access to the code so that they can make fixes in immediate, but this is dangerous.

 

×:Data validation errors

Data validation errors are wrong because an attacker cannot operate on the process execution sequence.

#32. Which of the following is NOT a benefit of VoIP?

〇:Security

Voice over Internet Protocol (VoIP) refers to a transmission technology that delivers voice communications over an IP network; IP telephony uses technology that is similar to TCP/IP and therefore similar in its vulnerabilities. Voice systems are vulnerable to application manipulation and unauthorized administrative access. It is also vulnerable to denial of service attacks against gateway and network resources. Eavesdropping is also a concern since data traffic is transmitted in clear text unless encrypted.

The term security is a difficult answer to choose from because it has a very broad meaning. However, information security scriptures such as CISSP are persistent in saying that VoIP has vulnerabilities. Although this answer is a bit over the top in practical terms, it was made to educate the public, because depending on the creator’s intentions, this issue may arise.

 

×:Cost

Wrong, because cost is an advantage of VoIP; with VoIP’s, a company becomes a dedicated alternative to a separate network dedicated to data transmission and voice transmission. For telephony features such as conference calling, call forwarding, and automatic redialing are freed up in VoIP, which is open source, while companies that use traditional communications charge for VoIP.

 

×:Convergence

Wrong because convergence is the advantage of VoIP. Convergence means the integration of traditional IP networks with traditional analog telephone networks.

 

×:Flexibility

Wrong, because flexibility is an advantage of VoIP. The technology is very simple, easy and supports multiple calls over a single Internet broadband connection.

#33. Which of the following formulas is closest to the risk relationship?

Risk is the multiplication of threats and vulnerabilities. If the threat is at least as great as the vulnerability is fatal, it is a significant impact, or risk. Therefore, the best illustration of the relationship between the four rules is the multiplier.

#34. A student is concerned about his future and wants to attack a political institution. What is this middle school student classified as an attacker?

〇:Hacktivist
A person who commits cracking acts for political purposes is called a hacktivist. Therefore, the correct answer is “hacktivist.
×: Hacker
A hacker is a person who is computer savvy.
×: Script kiddie
A script kiddie is a person who is not familiar with IT but uses tools to conduct cyber attacks. The phrase “junior high school student” is used, but this alone does not rule out a script kiddie.
×:Silent majority
The silent majority is the general public that does not actively engage in speech acts.

#35. Is it an identity management technology that can be used across business boundaries?

〇:Federation Identity

A federation identity is a portable identity and associated credentials that can be used across business boundaries. It allows users to authenticate across multiple IT systems and across the enterprise. Federation Identity is based on linking otherwise distinct identities of users in two or more locations without the need to synchronize or consolidate directory information. Federated Identity is an important component of e-commerce, providing businesses and consumers with a more convenient way to access distributed resources.

 

×:User Provisioning

User provisioning is incorrect because it refers to the creation, maintenance, and deactivation of user objects and attributes.

 

×:Directory

While most companies have some type of directory that contains information about company network resources and users, generally these directories are not utilized as spread across different companies. It is true that nowadays, with open APIs and cloud computing, there is a trend to deploy services through a single directory, but the directory service itself does not include resource sharing implications. In other words, it is just used as a shared service.

 

×:Web Access Management

Web Access Management (WAM) software is incorrect because it controls what users can access when using a Web browser to interact with Web-based corporate assets.

#36. Which network line should be used to ensure that traffic always uses the same path?

Circuit switching is a dedicated communication channel through a network. The circuit guarantees full bandwidth. The circuit functions as if the nodes were physically connected by cables.

#37. Which of the following is a structured walk-through test in disaster recovery testing?

〇:Representatives from each department meet and undergo validation.

Structured walk-through testing allows functional personnel to review the plan as it is fulfilled to ensure its accuracy and validity.

 

×:Ensures that some systems will run at alternate sites.

This is incorrect because it describes parallel testing.

 

 

×:Send a copy of the disaster recovery plan to all departments to verify its completeness.

This is incorrect because it describes a checklist test.

 

×:Take down the normal operation system.

This is incorrect because it describes a full interruption test.

#38. Which of the following is the most effective method of identifying backup strategies?

〇:Test the restore procedure.

The ability to successfully restore from a backup must be tested periodically. Therefore, the correct answer is: “Test the restore procedure.” will be

 

×:Ensure that all user data is backed up.

Making copies of user data is important, but copies are useless unless it is ensured that the copies can be restored.

 

×:Back up the database management system (DBMS) to your own specifications.

While it is a good idea to use measures to meet the proprietary specifications of the DBMS to ensure that transactional copies are usable, those copies will not be trusted unless the restores are tested.

 

×:Ensure that the backup log files are complete.

Monitoring backup logs for completion is good operational practice, but it is wrong because it is no substitute for regular testing of the backups themselves and their ability to truly recover from data loss.

#39. Which of the following incorrectly describes a directory service?

〇:Conforms to the X.509 standard and assigns a namespace to each object accessed in the database by LDAP.

Most companies have directories that contain information about company network resources and users. Most directories use a hierarchical database format based on the X.500 standard (not X.509) and a type of protocol such as LDAP (Lightweight Directory Access Protocol) that allows subjects and applications to interact with the directory The application can then use LDAP to access the directory. Applications can request information about a particular user by making an LDAP request to the directory, and users can request information about a particular resource using a similar request. The directory service assigns an Distinguished Name (DN) to each object in the database based on the X.500 standard to be accessed. Each distinguished name represents a set of attributes about a particular object and is stored as an entry in the directory.

 

×:Namespaces are used to manage objects in the directory.

This is incorrect because objects in a hierarchical database are managed by a directory service. Directory services allow administrators to configure and manage identification, authentication, permissions, and access control for the network. Objects in the directory are labeled and identified by namespace, which is how the directory service keeps objects organized.

 

×:Enforce security policies by performing access control and identity management functions.

This is incorrect because directory services enforce the security policy set by performing access control and identity management functions. For example, when a user logs into a domain controller in a Windows environment, the directory service (Active Directory) determines which network resources are accessible and which are not.

 

×:Administrators can configure and manage how identification takes place within the network.

Directory service is incorrect because it allows the administrator to configure and manage identification within the network. It also allows for the configuration and management of authentication, authorization, and access control.

#40. What is the difference between freeware and shareware?

Freeware is free software and can be used for free. Shareware is fully functional proprietary software that is initially free to use. Often a trial to test the software requires a fee to continue using it after 30 days. Thus, the correct answer is, “Freeware is free in perpetuity, while shareware is free for a set period of time.” will be.

#41. Sally is responsible for managing the keys in her organization. Which of the following is incorrect as secure key management?

〇:The expiration date should be set short.

Key management is critical for proper protection. Part of key management is to determine the key’s period of validity, which would be determined by the sensitivity of the data being protected. For sensitive data, periodic key changes are required and the key’s expiration date will be shortened. On the other hand, for less secure data, a key with a longer expiration date is not a problem.

 

×:Keys should be deposited in case of backup or emergency.

This is incorrect because it is true that keys must be deposited in the event of a backup or emergency situation. Keys are at risk of being lost, destroyed or damaged. Backup copies must be available and readily accessible when needed.

 

×:Keys must not be made public.

Of course. It is a key.

 

×:Keys should be stored and transmitted by secure means.

Wrong, since it is true that keys should be stored and transmitted by secure means. Keys are stored before and after distribution. If keys are distributed to users, they must be stored in a secure location in the file system and used in a controlled manner.

#42. We are implementing a new network infrastructure for our organization. The new infrastructure uses carrier sense multiple access with collision detection (CSMA / CD). What are you trying to implement?

Carrier Sense Multiple Access Collision Detection (CSMA / CD) is used for systems that can transmit and receive simultaneously, such as Ethernet. If two clients listen at the same time and make sure the line is clear, both may transmit at the same time, causing a collision. Collision Detection (CD) is added to solve this scenario. The client checks to see if the line is idle and transmits if it is idle. If in use, they wait for a random time (milliseconds). During transmission, they monitor the network and if more input is received than transmitted, another client is also transmitting and sends a jam signal instructing other nodes to stop transmitting, wait a random time and then start transmitting again.

#43. Which of the following is a centralized access control protocol?

〇:Diameter

Diameter is an authentication, authorization, and audit (AAA) protocol that not only provides the same kind of functionality as RADIUS and TACACS, but also offers more flexibility and capabilities to meet the emerging demands of today’s complex and diverse networks. Once all remote communication is done via Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP) connections, users can authenticate themselves via Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP) to authenticated. The technology has become much more complex and there are multiple devices and protocols to choose from over the ever increasing Diameter protocol, Mobile IP, PPP, Voice over IP (VoIP), and other over Ethernet, wireless devices, smart phones, and other devices can authenticate themselves to the network using roaming protocols.

 

×:Watchdog

Watchdog timers are wrong because such processes are generally used to detect software failures such as abnormal termination or hangs. The watchdog function sends out “heartbeat” packets to determine if the service is responding. If not, the process can be terminated or reset. These packets help prevent software deadlocks, infinite loops, and process prioritization problems. This feature can be used in the AAA protocol to determine if a packet needs to be retransmitted and if a problem occurs and the connection should be closed and reopened, but it is not in the access control protocol itself.

 

×:RADIUS

Remote Authentication Dial-In User Service (RADIUS) is wrong because it is a network protocol and provides client/server authentication, authorization, and auditing for remote users.

 

×:TACACS

Terminal Access Controller Access Control System Plus (TACACS ) is incorrect because it provides essentially the same functionality as RADIUS.

#44. Measuring the damage and recovery requirements by different indicators helps quantify the risk. which is correct about the RPO (Recovery Point Objective) and RTO (Recovery Time Objective)?

RPO (Recovery Point Objective) is the target value for recovering data at a point in the past when a failure occurs. When a failure occurs, the data currently handled is lost. The lost data must be recovered from backups, but it is important to know how far in the past the backups are from the current point in time.

RTO (Recovery Time Objective) is a target value that defines when the data should be recovered in the event of a failure. In the event of a failure, the service must not be unavailable indefinitely. Failure response procedures and disaster drills must be implemented to establish a target value for the time from the occurrence of a failure to the startup of service.

#45. Matthew, the company’s business continuity coordinator, helps recruit members to the Business Continuity Plan (BCP) Committee. Which of the following is an incorrect explanation?

〇:Meetings should be conducted with a fixed number of members and should be as small as possible.

The BCP committee should be large enough to represent each department within the organization. It should consist of people who are familiar with the different departments within the company, as each department has unique functions and unique risks and threats. All issues and threats will be formulated when they are brought in and discussed. This cannot be done effectively with a few divisions or a few people. The committee must consist of at least business unit, senior management, IT, security, communications, and legal personnel.

Conducting meetings with a fixed number of members and as few as possible is certainly not a misinterpretation of “elite few. However, one must know what is the “best” answer and answer it.

 

×:Committee members should be involved in the planning, testing, and implementation phases.

The answer is incorrect because it is correct that committee members need to be involved in the planning, testing, and implementation phases. If Matthew, the coordinator of the BCP, is a good business leader, he will consider that it is best to make team members feel ownership over their duties and roles. The people who develop the BCP must also be the ones who implement it. If some critical tasks are expected to be performed during a time of crisis, additional attention should be given during the planning and testing phase.

 

×:The business continuity coordinator should work with management to appoint committee members.

This is incorrect because the BCP coordinator should work with management to appoint committee members. However, management’s involvement does not end there. The BCP team should work with management to finalize the goals of the plan, identify the critical parts of the business that must be handled first in the event of a disaster, and identify department and task priorities. Management also needs to help direct the team on the scope and specific goals of the project.

 

×:The team should consist of people from different departments within the company.

This is incorrect because the team should consist of people from different departments within the company. This will be the only way for the team to consider the risks and threats that each department faces according to the organization.

#46. What is the intention of preparing artificially vulnerable network domains?

〇:For early detection or enclosure in the event of an attack.

Attackers will conduct an investigation before launching a substantial attack. In such cases, a vulnerable network can provide preventative information such as where the attacker is accessing the network from. This is because only an attacker would have the incentive to break into the network. Vulnerable network domains, such as honeypots, make this kind of intrusion easier and clarify the attacker’s behavior. Thus, the correct answer is “to detect or enclose them early in the event of an attack.” will be

 

×:Debugging environment for when a system outage occurs in the current environment.

The answer is not to intentionally create a vulnerable environment. It is only the result of creating an environment that is vulnerable.

 

×:Aiming to prevent regressions due to old vulnerabilities.

Even if it is an old vulnerability, it should be addressed and there is no point in allowing it to remain.

 

×:A special environment for running a product with a low version that is no longer supported.

It is not an answer to intentionally create a vulnerable environment. It is merely the result of creating an environment that is vulnerable.

#47. Which of the following is the most difficult to discover keys among known-plaintext attacks, selective-plaintext attacks, and adaptive-selective-plaintext attacks?

〇:Known Plaintext Attacks

A known-plaintext attack is a situation in which a decryptor can obtain plaintext indiscriminately. A ciphertext-alone attack is a situation where a decryptor can acquire ciphertext indiscriminately. A known-plaintext attack acquires the plaintext but does not know what ciphertext it is paired with, meaning that decryption is attempted with only two random ciphertexts. In this situation, it is difficult to decrypt. Therefore, the correct answer is “known-plaintext attack.

 

×:Selective Plaintext Attack

A choice-plaintext attack is a situation in which the decryptor can freely choose the plaintext to acquire and obtain the ciphertext.

 

×:Adaptive Choice Plaintext Attack

An adaptive choice-plaintext attack is a situation in which the decryptor can freely choose which plaintext to acquire and acquire the ciphertext, and can repeat the acquisition again after seeing the result.

 

×:None of the above

It is rare for the answer to be “none of the above” when the choice is “most of the above.

#48. Communication speed has become a problem and we want to renew our Wi-Fi. I want to get the fastest possible connection speed. Which Wi-Fi standard should we use?

#49. We have tested our software and found over 10,000 defects. What should the next step be?

〇:Calculate the potential impact for fatal errors.

Software testing is a must, but when that testing reveals numerous defects, it must be handled with care. Systems do not have the same concept as human forgetfulness, but it is not realistic to ask someone who scored 30 on this week’s test to score 100 on next week’s test.

Before any corrections can be made, the data taken from the test must be analyzed with the test completed, including log reviews. Priority must be given to determining what to implement first and what is acceptable and unacceptable. Think about qualitative risk analysis; if it is unlikely and has little impact, it can be left alone and focus on high priority items. Thus, the correct answer is, “Calculate the likelihood of impact for fatal errors.” will be.

 

×:Fix them all.

If many defects are found, it is likely that a lot of time will be taken to deal with their correction.

 

×:Leave them alone because of the huge number.

In principle, it is unacceptable to leave defects unattended.

 

×:Calculate the potential impact for all errors.

Performing an analysis for all errors can also be very work intensive.

#50. Which formulas are used in a Business Impact Analysis (BIA) assessment?

#51. Which of the following is a drawback of the symmetric key system?

〇:Keys will need to be distributed via a secure transmission channel.

For two users to exchange messages encrypted with a symmetric algorithm, they need to figure out how to distribute the key first. If the key is compromised, all messages encrypted with that key can be decrypted and read by an intruder. Simply sending the key in an email message is not secure because the key is not protected and can easily be intercepted and used by an attacker.

 

×:Computation is more intensive than in asymmetric systems.

That is incorrect because it describes the advantages of symmetric algorithms. Symmetric algorithms tend to be very fast because they are less computationally intensive than asymmetric algorithms. They can encrypt and decrypt relatively quickly large amounts of data that take an unacceptable amount of time to encrypt and decrypt with asymmetric algorithms.

 

×:Much faster operation than asymmetric systems

Symmetric algorithms are faster than asymmetric systems, but this is an advantage. Therefore, it is incorrect.

 

×:Mathematically intensive tasks must be performed

Asymmetric algorithms are wrong because they perform a mathematically intensive task. Symmetric algorithms, on the other hand, perform relatively simple mathematical functions on bits during the encryption and decryption process.

#52. SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between systems on different security domains. SAML allows for the sharing of authentication information, such as how the authentication was performed, the attributes of an entity, and the permissions to which the entity has access. Which of the following definitions is associated with the correct SAML component?

〇:SAML assertions are used to enable identity federation and distributed systems.

SAML provides a model that allows two parties to share authentication information about one entity. The two parties are considered a Service Provider (SP) and an Identity Provider (IdP). The Identity Provider asserts information about the principal, such as whether the subject is authenticated or has certain attributes. The service provider uses the information provided by the identity provider to make access decisions about the services it provides, including whether to trust the identity provider’s assertions. By trusting the identity provider’s information, the service provider can provide services without requiring the principal to authenticate again. This framework enables federated identification and distributed authentication across domains.

A SAML assertion is information about a principal contained in a SAML response that is returned to the service provider after authentication has been processed by the identity provider.

 

×:Two SAML assertions (authentication and authorization) are used to indicate that an authority by SAML has validated a particular subject.

The Identity Provider will not return two SAML assertions; one assertion will be returned per request.

 

×:The SAML binding specification describes how to embed SAML messages within the TCP and UDP protocols.

It is not classified in the sense of within the TCP and UDP protocols.

 

×:The SAML profile has a definition for issuing a refresh token.

Refresh tokens are a concept in the OAuth/OIDC family.

#53. Server cluster configurations are taken for critical applications, but what functions are achieved by this configuration?

Clustering is designed for fault tolerance. It is often combined with load balancing, but they are essentially separate. Clustering can make an operation active/active. On top of that, the load balancing feature handles traffic from multiple servers. Active/passive, on the other hand, has a designated primary active server and a secondary passive server, with the passive sending keep-alives or heartbeats every few seconds.

#54. There are many types of viruses that hackers can use to damage your system. Which of the following is NOT a correct description of a polymorphic type virus?

〇:Intercept anti-malware calls to the operating system for file system information.

This is a “no” question. Polymorphic viruses attempt to fool anti-malware scanners. In particular, they use methods to generate operational copies. Even if the anti-malware software detects and disables one or two copies, the other copies remain active in the system.

This problem must be solved by process of elimination. What definitions are polymorphic viruses? If you remember the word list “what is a polymorphic virus,” you may not understand what makes a polymorphic virus unique. The most striking feature of polymorphic viruses is that they repeatedly change entities.

 

×:Using noise, mutation engines, or random number generators to change the sequence of instructions.

Polymorphic-type viruses may change the sequence of instructions by including noise or false instructions along with other useful instructions. They can also use mutation engines and random number generators to alter the sequence of instructions in the hope that they will not be detected. The original functionality remains intact, but the code is altered, making it nearly impossible to identify all versions of the virus using a fixed signature.

 

×:Different encryption schemes that require different decryption routines can be used.

Polymorphic-type viruses can use different encryption schemes that require different decryption routines. This requires an anti-malware scan to identify all copies of this type of virus, one for each possible decryption method. Polymorphic virus creators hide the encrypted virus payload and add decryption methods to the code. Once encrypted, the code becomes meaningless, but that does not necessarily mean that the encrypted virus is a polymorphic virus and thus escapes detection.

 

×:Create multiple and various copies.

Polymorphic viruses generate multiple, varied copies in order to avoid detection by anti-malware software.

#55. Which of the following is an incorrect benefit of virtualization?

〇:Operating system patching is easier.

This is an incorrect choice question. Virtualization does not simplify operating system patching. In fact, it complicates it by adding at least one additional operating system. Each operating system differs from the typical version configuration, adding to the complexity of patching. The server’s own operating system runs as a guest within the host environment. In addition to patching and maintaining the traditional server operating system, the virtualization software itself must be patched and maintained.

For this question, we do not require an understanding of all the technical systems of virtualization. What is required here is a selection of answers based on a process of elimination.

 

×:I can build a secure computing platform.

Building a secure computing platform may not be a feature of virtualization per se. However, can we build a secure environment? This is not a false choice because it cannot be ruled out.

 

×:It can provide fault and error containment.

Virtualization can be host independent. In terms of containment, it can be interpreted as being able to provide fault and error containment through independence from physical servers. Therefore, it cannot be denied and is therefore not an incorrect choice.

 

×:It can provide powerful debugging capabilities.

Virtualization can reproduce a unique environment, not just put up a clean virtual host. Therefore, it is undeniable and therefore out of the wrong choice.

#56. Which is the first step in a business impact analysis?

〇:Creating Data Collection Techniques

Of the steps listed, the first step in a Business Impact Analysis (BIA) is to create a data collection technique. The BCP committee will use questionnaires, surveys, and interviews to collect key person information on how different tasks are accomplished within the organization, along with any relevant dependencies of processes, transactions, or services. Process flow diagrams should be created from this data and used throughout the BIA and planning and development phases.

 

×:Risk calculations for each different business function

This is incorrect because the risk for each business function is calculated after the business function has been identified. And before that happens, the BCP team needs to collect data from key personnel. To calculate the risk for each business function, qualitative and quantitative impact information must be collected, properly analyzed, and interpreted. Once the data analysis is complete, it should be reviewed with the most knowledgeable people in the company to ensure that the results are relevant and to explain the actual risks and impacts facing the organization. This will flush out any additional data points that were not captured initially and allow for a full understanding of all possible business impacts.

 

×:Identifying Critical Business Functions

Image B is incorrect because the identification of critical business functions is done after the BCP committee has learned about the business functions that exist by interviewing and surveying key individuals. Once the data collection phase is complete, the BCP committee conducts an analysis to determine which processes, devices, or business activities are critical. If a system stands on its own, does not affect other systems, and is less critical, it can be classified as a Tier 2 or Tier 3 recovery step. In other words, these resources are not processed in the recovery phase until the most critical (Tier 1) resources are up and running.

 

×:Vulnerability and Threat Identification to Business Functions

This is not the first step and is incorrect because it identifies vulnerabilities and threats to business functions toward the end of the business impact analysis. It is the last of the steps listed in the answer. Threats can be man-made, natural, or technical. It is important to identify all possible threats and estimate their likelihood of occurring. When developing these plans, some issues may not be immediately apparent. These issues are best addressed by groups conducting scenario-based exercises. This ensures that when the threat becomes reality, the plan will have an impact on all business tasks, departments, and critical operations. The more issues that are planned for, the better prepared you will be should these events occur.

#57. The CA is responsible for revoking the required certificates. Which of the following adequately describes CRLs and OCSPs?

〇:OCSP is a protocol developed specifically to check CRLs during the certificate validation process.

A Certificate Authority (CA) is responsible for creating certificates, maintaining and distributing them, and revoking them when necessary. Revocation is handled by the CA and the revoked certificate information is stored in a Certificate Revocation List (CRL). This is a list of all revoked certificates. This list is maintained and updated periodically. A certificate is revoked if the key owner’s private key has been compromised, if the CA has been compromised, or if the certificate is incorrect. If a certificate is revoked for any reason, the CRL is a mechanism for others to inform you of this information. The Online Certificate Status Protocol (OCSP) uses this CRL; when using CRLs, the user’s browser must examine the CRL value to the client to see if the accreditation has been revoked or the CA is constantly checking to make sure they have an updated CRL. If OCSP is implemented, it will do this automatically in the background. It performs real-time verification of the certificate and reports back to the user whether the certificate is valid, invalid, or unknown.

 

×:CRL was developed as a more efficient approach to OCSP.

CRLs are often incorrect because they are a cumbersome approach; OCSP is used to deal with this tediousness; OCSP does this work in the background when using CRLs; OCSP checks the CRL to see if the certificate has been revoked by Checks.

 

×:OCSP is a protocol for submitting revoked certificates to CRLs.

OCSP is incorrect because it does not submit revoked certificates to the CRL; the CA is responsible for certificate creation, distribution, and maintenance.

 

×:CRL provides real-time validation of certificates and reports to OCSP.

Incorrect because CRL does not provide real-time validation of certificates to OCSP.

#58. What is the difference between awareness and trainning?

Awareness is to inform the organization’s members of the information they already have in order to make them more vigilant again. Tranning is the input of information that is unknown to the members of the organization. Therefore, the difference between awareness-raising and tranning is whether the target audience is already aware of the information.

#59. What is a synthetic transaction?

To test the application, normal user behavior must be emulated. However, common loads of user activity are not available in the testing environment. Therefore, common user transaction scripts can be built to facilitate different forms of testing.

#60. What kind of person does the word sabotage, the root of the word sabotage, refer to?

Sabotage is an attack by an insider.

#61. Which of the following would not be considered an attack motivated by gaining money?

Distributed Denial of Service (DDoS) attacks usually do not provide financial gain to the attacker. Often, the motivation is revenge, disagreement with the organization’s policy decisions, or the attacker proving the extent of his or her animosity toward the organization. Certainly, it can be used to bloat the cost of a pay-as-you-go cloud service by causing it to consume more resources than expected by accessing it in large volumes, but it is a mistake in that it is not the financial objective of the parties involved.

#62. There are several attacks that programmers should be aware of. When an attacker attempts to execute arbitrary code, what type of attack is indicated?

〇:Buffer overflow

A buffer is an area reserved by an application to store something in it, like some user input. After the application receives input, the instruction pointer is put into the buffer. A buffer overflow occurs when the application accidentally allows the input to overwrite the instruction pointer in the code and write it to the buffer area. Once the instruction pointer is overwritten, it can be executed under the application’s security context.

 

×:Traffic Analysis

Traffic Analysis is incorrect because it is a method of revealing information by looking at traffic patterns on the network.

 

×:Race Condition

Incorrect because it does not indicate a race condition attack; if two different processes need to perform their tasks on a resource, they need to follow the correct order.

 

×:Covert Storage

Incorrect because in a covert storage channel, processes are capable of communicating through some type of storage space on the system.

#63. We have been paying a software vendor to develop software on a custom basis, but that vendor may be out of business. Since it does not have access to the code, it cannot be retained. In what ways can the company prevent this?

〇:Software Escrow

If you do not have access to the software, but the developer may be out of business, you should plan for what to do after that out-of-business event. Software escrow means that the third party retains the source and compiled code, backup manuals, and other support materials. The agreement between the software vendor, the customer, and the third party would typically be that the customer would only have access to the source code when the vendor goes out of business and in the event of the vendor’s inability to fulfill its stated responsibilities or breach of the original agreement. The customer is protected because they can gain access to the source code and other materials through a third-party escrow agent.

 

×:Reciprocal Treatment Agreement

Although the term “reciprocal treatment agreement” does not exist, a close concept is mutual assistance agreements. A Mutual Assistance Agreement (MAA) is a promise to support each other in the event of a disaster by sharing facilities. There are times when you want to do something about a disaster, but you don’t have the funds to do it. In such a case, you can find a similar organization and agree to cooperate with each other in the event of a disaster.

 

×:Electronic Data Vault

Electronic data vaulting (e-vaulting) is the use of a remote backup service to electronically transmit backups off-site at regular intervals or when files are changed.

 

×:Business interruption insurance

Although the term business interruption insurance does not exist, it can be interpreted as a concept similar to insurance in the event of business interruption. Insurance is typically applied against financial risk. In this issue, software escrow is more appropriate because we want to continue access to the software.

#64. Frank is responsible for the security of the company’s online applications, web server, and web-based activities. Web applications have the ability to be dynamically “locked” so that multiple users cannot simultaneously edit web pages or overwrite each other’s work. The audit revealed that even with this software locking capability properly configured, multiple users can modify the same web page at the same time. Which of the following best describes this situation?

〇:TOC/TOU

Certain attacks can take advantage of the way a system processes requests and performs tasks. A TOC/TOU attack handles a series of steps that the system uses to complete a task. This type of attack takes advantage of the reliance on the timing of events occurring in a multitasking operating system; TOC/TOU is a software vulnerability that allows the use of condition checking (i.e., credential verification) and the results from that condition checking function. In the scenario in this question, the fact that the web application is likely correctly configured indicates that the programming code of this application has this type of vulnerability embedded in the code itself.

 

×:Buffer overflow

When too much data is accepted as input to a particular process, a buffer overflow occurs. This is incorrect because it does not match the event in the problem statement. A buffer is an allocated segment of memory. A buffer can overflow arbitrarily with too much data, but to be used by an attacker, the code inserted into the buffer must be of a specific length and require a command to be executed by the attacker. These types of attacks are usually exceptional in that the fault is segmented, or sensitive data is provided to the attacker.

 

×:Blind SQL Injection

Blind SQL injection attacks are wrong because they are a type of SQL injection attack that sends true or false questions to the database. In a basic SQL injection, the attacker sends specific instructions in SQL format to query the associated database. In a blind SQL attack, the attacker is limited to sending a series of true-false questions to the database in order to analyze the database responses and gather sensitive information.

 

×:Cross Site Request Forgery (CSRF)

Cross Site Request Forgery (CSRF) is incorrect because it is an attack type that attempts to trick the victim into loading a web page containing malicious requests or operations. The attack operation is performed within the context of the victim’s access rights. The request inherits the victim’s identity and performs undesirable functions for the victim. In this type of attack, the attacker can cause the victim’s system to perform unintended actions such as changing account information, retrieving account data, or logging out. This type of attack could be related to the scenario described in this question, but focuses on how the user can bypass the locking mechanism built into the web application. The logic in the programming code is incorrectly developed and the locking function is bypassed because a rigorous series of checks and usage sequences are not performed correctly.

#65. Which of the following are ways to defend against cross-site tracing?

Cross-site tracing is an attack to obtain authentication information by embedding TRACE method HTTP communication in a web page. Suppose the TRACE method is embedded in the login screen by XSS. After the password to log in is sent, it is returned by TRACE and comes back. The password that has just been sent is returned to the browser, leading to a compromise.

#66. Which of the following comes closest to defining a virtual machine?

〇:A virtual instance of an operating system
A virtual machine is a virtual instance of an operating system. A virtual machine, also called a guest, runs in a host environment. Multiple guests can run simultaneously in the host environment. Virtual machines pool resources such as RAM, processors, and storage from the host environment. This has many benefits, including increased processing efficiency. Other benefits include the ability to run legacy applications. For example, an organization may choose to run legacy applications on Windows 7 instances (virtual machines) after Windows 7 is rolled out.
×:Hardware running multiple operating system environments simultaneously.
This is incorrect because virtual machines are not hardware. A virtual machine is an instance of an operating system running on hardware. A host can run multiple virtual machines. That is, you can have essentially one computer running different operating systems simultaneously. With virtual machines, the workloads of several unused servers can be consolidated into one host, saving hardware and administrative management efforts.
×:Physical environment for multiple guests
Incorrect because the virtual machine serves and functions within a software emulation. The host provides resources such as memory, processors, buses, RAM, and storage for the virtual machines. Virtual machines share these resources, but do not have direct access to them. The host environment, which is responsible for managing system resources, acts as an intermediary between the resources and the virtual machines.
×:Environments with full access to legacy applications
Many legacy applications are incorrect because they are not compatible with certain hardware and newer operating systems. As a result, applications generally do not fully utilize server software and components. Virtual machines emulate an environment that allows legacy applications and other applications to fully utilize available resources. This is the reason for using virtual machines, but the benefits and definitions are different.

#67. What is called taking reasonable action to prevent a security breach?

〇:Due Care

Confidentiality means that the company does everything it could reasonably have done to prevent a security breach under the circumstances and takes appropriate control and action in the event of a security breach. In short, it means that the company is acting responsibly by practicing common sense and prudent management. If a company has a facility that is not fire-immune, its arsonist will be only a small part of this tragedy. The company is responsible for providing fire-resistant building materials, alarms, exits, fire extinguishers, and backup fire detection and suppression systems, all critical information specific areas that could be affected by a fire. If a fire were to burn the company’s building and all records (customer data, inventory records, and information needed to rebuild the business) were to disappear, the company would not take precautions to ensure that it is protected against that loss. For example, it would be possible to back up to an off-site location. In this case, employees, shareholders, customers, and anyone else affected could potentially sue the company. However, if the company has done all that is expected of it in terms of the points mentioned so far, it is difficult to sue without success if proper care (dee care) is not taken.

 

×:Downstream Liability

Is wrong because one firm’s activities (or lack thereof) may have a negative impact on other firms. If either company fails to provide the required level of protection and its negligence affects the partners with whom it cooperates, the affected company can sue the upstream company. For example, suppose Company A and Company B have built an extranet. Company A has not implemented controls to detect and address viruses. Company A is infected with a harmful virus, which infects Company B through the extranet. The virus destroys critical data and causes a major disruption to Company B’s production. Company B can therefore sue Company A for negligence. This is an example of downstream liability.

 

×:Liability

Incorrect, as it generally refers to the obligation and expected behavior or actions of a particular party. Obligations can have a defined set of specific actions required, which is a more general and open approach that allows parties to determine how to fulfill specific obligations.

 

×:Due diligence

A better answer to this question. Liability is not considered a legal term as with the other answers. Due diligence is because the firm has properly investigated all of its possible weaknesses and vulnerabilities. Before you can understand how to properly protect yourself, you need to know that you are protecting yourself. To understand the real level of risk, investigate and assess the real level of vulnerability. Even after these steps and assessments have been made, effective controls and protective measures can be identified and implemented. Due diligence means identifying all potential risks, but an appropriate response is one that actually mitigates the risk.

#68. Layer 2 of the OSI model has two sublayers. What are the two IEEE standards that represent these sublayers and technologies?

The data link layer or Layer 2 of the OSI model adds a header and trailer to the packet to prepare the packet in binary format in local area network or wide area network technology for proper line transmission. Layer 2 is divided into two functional sublayers. The upper sublayer is logical link control (LLC), which is defined in the IEEE 802.2 specification. It communicates with the network layer above the data link layer. Below the LLC is the Media Access Control (MAC) sublayer, which specifies interfaces with the protocol requirements of the physical layer.

#69. SElinux is set up. Which access control will be followed?

〇:Mandatory Access Control (MAC)

Mandatory Access Control (MAC) is an access control that enforces access privileges by pre-classifying resources into levels. There are several types of access rights to data files. There are several types of access rights to data files: the user of the data file, the owner who creates the data file, and the administrator who decides which owner can create the data. SELinux, TOMOYO Linux, Trusted BSD, and Trusted Solaris are methods used by MACs.

 

×:Discretionary Access Control (DAC)

Discretionary Access Control (DAC) is an access control method that allows the owner of an access target to change access privileges.

 

×:Role Access Control (RAC)

There is no such term. A close equivalent is role-based access control, which divides accounts by role and applies access control to those roles.

 

×:Voluntary Access Control (VAC)

There is no such term.

#70. Which of the following is the most appropriate relationship between SSL and TLS?

〇:TLS is an open community version of SSL.

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols used to protect communications by encrypting segments of a network connection. SSL is a proprietary protocol and TLS was developed by a standards body, making it an open community protocol.

 

×:TLS is an open community version of SSL. SSL is a proprietary protocol and TLS was developed by a standards body, making it an open community protocol. x: The SSL protocol can be modified by developers to extend its capabilities.

This is incorrect because SSL is a proprietary protocol developed by Netscape. This means that the technical community cannot easily interoperate and extend SSL to extend to its functionality.

 

×:SSL is an open community protocol while TLS is a proprietary protocol.

The meaning and matching are reversed.

 

×:SSL is an extended version and backward compatible with TLS.

Wrong, since TLS is actually more extensible than SSL and is not backward compatible with SSL.

#71. Encryption provides different security depending on the procedure and & algorithm. Which of the following provides authentication, non-repudiation, and integrity?

〇:Digital Signature

A digital signature is a hash value encrypted with the sender’s private key. The act of signing means encrypting a hash value of a message with a private key. A message can be digitally signed, providing authentication, non-repudiation, and integrity. The hash function guarantees the integrity of the message, and the signature of the hash value provides authentication and non-repudiation.

 

×:Encryption Algorithms

Encryption algorithms are wrong because they provide confidentiality. Encryption is most commonly performed using symmetric algorithms. Symmetric algorithms can provide authentication, non-repudiation, and integrity as well as confidentiality.

 

×:Hash Algorithms

Hash algorithms are wrong because they provide data integrity. Hash algorithms generate a message digest, which detects whether modifications have been made (also called a hash value). The sender and receiver individually generate their own digests, and the receiver compares these values. If they differ, the receiver can know the message has been modified. Hash algorithms cannot provide authentication or non-repudiation.

 

×:Encryption paired with digital signatures

This is incorrect because encryption and digital signatures provide confidentiality, authentication, non-repudiation, and integrity. Encryption alone provides confidentiality. And digital signatures provide authentication, non-repudiation, and integrity. The question requires that it can provide authentication, non-repudiation, and integrity. It is a nasty question.

#72. Database software must meet a requirement called the ACID test. In OLTP, why does the database software perform one of the requirements of the ACID test, transaction atomicity?

〇:To allow the database to execute transactions as a single unit without interruption.

Online transaction processing (OLTP) is used when databases are clustered to provide high fault tolerance and performance. It provides a mechanism to monitor and address problems as they occur. For example, if a process stops functioning, the monitoring function within OLTP will detect and attempt to restart the process. If the process cannot be restarted, the transaction that occurred is rolled back to ensure that no data has been corrupted or that only a portion of the transaction occurred; OLTP records when the transaction occurred (in real time). Usually multiple databases in a distributed environment are updated.

This classification by the extent to which transaction processing is appropriate is very complex. Therefore, database software must implement ACID characteristics. Among them is atomicity, which means that the transaction is either executed entirely or not executed at all. It is the property that a transaction must either be executed completely or not at all.

When a question like this is answered incorrectly, judging that you could not solve it because you did not know OLTP will hinder your future study methods. Although the question text is worded in a complicated way, it is more important to understand what atomicity is in ACID than to memorize the definition of OLTP to solve the actual question.

 

×:To be able to establish database consistency rules.

It enforces the consistency rules as stated in the database security policy, but does not imply transaction atomicity.

 

×:To prevent rollbacks from occurring.

Transaction atomicity does not refer to suppressing rollbacks.

 

×:To prevent concurrent processes from interacting with each other.

This falls under independence, isolation, and segregation. Independence, isolation, and quarantine (isolation) means that the processes are hidden from other operations during processing. It is the property that even if multiple transactions are executed simultaneously, they must not produce the same processing results as if they were executed alone.

#73. Which authentication types are PINs, passwords, and passphrases?

Type 1 authentication treats what you know as credentials. This is accomplished through passwords, passphrases, PINs, etc., and is also referred to as the knowledge factor.

#74. An attacker used a brute force attack to break my password. How did you know it was a brute force attack?

Brute force can be used to decrypt the plaintext, given enough time. This is valid for all key-based ciphers except one-time pads. Eventually the data will be decrypted, but so many false positives will occur that the data will be rendered useless.

#75. We have a document that has been labeled as confidential information. Some of the text contained information that should be treated as Critical Secret Information above Confidential Information. How should this be handled?

〇:Review labeling and treat as critical confidential information.

Labeling is the process of sorting data according to its level of confidentiality. Labeling helps clarify the confidentiality level of data management. If the labeling is incorrect, it should be corrected at any time to manage the data in accordance with the confidentiality level. Therefore, “Review the labeling and treat it as critical confidential information.” is the correct answer.

 

×:The entire sentence should be treated as confidential information because the business should be flexible.

This is not an appropriate operation because the text containing critical confidential information is treated as confidential information.

 

×:As supplemental information to the document, state that “a part of the text contains material confidential information.

This is not a fundamental solution because stating this as supplementary information is in effect treating the information as different confidential levels.

 

×:Destroy the document because it is impossible for different confidential information to be crossed.

Destroying the document is not an appropriate operation because it is a damage to one’s own assets.

#76. Which of the following is NOT related to data integrity?

〇:Extraction of data shared with unauthorized entities

This is a problem of selecting unrelated items. Extraction of data shared with unauthorized entities is a confidentiality issue. Although it is complicatedly worded, the operations on the data are unauthorized and extraction, and none of them include the destruction of data, which is the primary focus of integrity. Therefore, the correct answer is “extraction of data shared with unauthorized entities.

In solving this problem, it is not necessary to know what an entity is. The focus is on whether any modification or destruction has taken place.

 

×:Unauthorized manipulation or alteration of data

Mistake. Because integrity is associated with unauthorized manipulation or alteration of data. Integrity is maintained when unauthorized modification is prevented. Hardware, software, and communication mechanisms must work together to correctly maintain and process data and move data to its intended destination without unexpected changes. Systems and networks must be protected from outside interference and contamination.

 

×:Unauthorized data modification

Unauthorized data modification is a mistake as it relates to integrity. Integrity is about protecting data, not changing it by users or other systems without authorization.

 

×:Intentional or accidental data substitution

Incorrect because intentional or accidental data substitution is associated with integrity. Integrity is maintained when assurances of the accuracy and reliability of information and systems are provided along with assurances that data will not be tampered with by unauthorized entities. An environment that enforces integrity prevents attacks, for example, the insertion of viruses, logic bombs, or backdoors into the system that could corrupt or replace data. Users typically incorrectly affect the integrity of the system and its data (internal users may also perform malicious acts). For example, a user may insert incorrect values into a data processing application and charge a customer $3,000 instead of $300.

 

#77. The Recovery Time Objective (RTO) and the Maximum Tolerable Downtime (MTD) metric have similar roles, but their values are defined differently. Which of the following best describes the difference between RTO and MTD metrics?

MTD represents the time it takes to signify severe and irreparable damage to the reputation and bottom line of an organization; RTO values are smaller than MTD values; RTO assumes that there is a period of acceptable downtime.

#78. Which of the following positions would be most desirable as the person who issues or is responsible for security measures?

〇:CEO

Security measures should be raised together with business strategy and should be issued from the top, the CEO. Therefore, the correct answer is “CEO.

 

×:CIO

Abbreviation for Chief Information Officer. Certainly, security measures may be issued by the CIO. However, the CIO is not the correct answer here, because it is “more desirable” to have the CEO, who is the top manager responsible for management, issue the security measures.

 

×:Site Manager

The person who issues or is responsible for security measures should be the person responsible for management. This is not the correct answer.

 

×:CTO

Abbreviation for Chief Technology Officer. The Chief Technology Officer’s main role is to promote and protect the organization’s research and technology. This is not the correct answer here, as the CEO is “more desirable” when security measures, including organizational management and governance, are issued.

#79. Which of the following describes the relationship between COBIT and ITIL?

〇:COBIT defines IT goals, ITIL provides process-level procedures

COBIT is a framework developed by ISACA (formerly the Information Systems Audit and Controls) and the IT Governance Institute (ITGI). It defines goals for controls, not just security needs, to ensure that IT is properly managed and that IT is responsive to business needs. The IT Infrastructure Library (ITIL) is the de facto standard for IT service management best practices. A customizable framework, ITIL provides goals, the general activities required to achieve these goals, and the input and output values for each process required to achieve these determined goals. In essence, COBIT addresses “what needs to be accomplished” and ITIL addresses “how to accomplish”.

 

×:COBIT is a model of IT governance, ITIL is a model of corporate governance.

While COBIT can be used as a model for IT governance, ITIL is wrong because it is not a model for corporate governance. In fact, the Committee of Sponsoring Organizations of the Treadway Commission (COSO) is a model of corporate governance. COBIT is derived from the COSO framework. COBIT can be thought of as a way to accomplish many COSO goals, but only from an IT perspective. To achieve many of the goals addressed in COBIT, organizations can use ITIL, which provides process-level steps to achieve IT service management goals.

 

×:COBIT is a model for corporate governance, ITIL is customizable for IT service management.

As mentioned above, COBIT is incorrect because it can be used as a model for IT governance, not corporate governance. COSO is a model of corporate governance. The second half of the answer is correct. ITIL is a customizable framework and is available as either a series of books or online for IT service management.

 

×:COBIT provides a business objectives framework, ITIL provides an IT service level objectives framework.

This is inappropriate because COBIT defines the control objectives that should be used to properly manage IT, enabling IT to address business needs as well as IT security needs. ITIL provides steps to achieve IT service management goals related to business needs. ITIL was created because of the increased reliance on information technology to meet business needs.

#80. The importance of protecting audit logs generated by computers and network devices is being stressed more than ever before, as required by and as per many regulations today. Which of the following does not explain why audit logs should be protected?

〇:The format of the audit log is unknown and is not available to the intruder in the first place.

Audit tools are technical controls that track activity within a network, on a network device, or on a specific computer. Auditing is not activity that denies an entity access to a network or computer, but it tracks activity so that the security administrator can understand the type of access made, identify security violations, or alert the administrator of suspicious activity. This information points out weaknesses in other technical controls and helps the administrator understand where changes need to be made to maintain the required level of security within the environment. Intruders can also use this information to exploit these weaknesses. Therefore, audit logs should be protected by controls on privileges, permissions, and integrity, such as hashing algorithms. However, the format of system logs is generally standardized for all similar systems. Hiding the log format is not a normal measure and is not a reason to protect audit log files.

 

×:If not properly protected, audit logs may not be admissible during prosecution.

This is incorrect because great care must be taken to protect audit logs in order for them to be admissible in court. Audit trails can be used to provide alerts about suspicious activity that can be investigated later. In addition, it is useful in determining exactly how far away the attack took place and the extent of any damage that may have occurred. It is important to ensure that a proper chain of custody is maintained so that all data collected can be properly and accurately represented in case it needs to be used in later events such as criminal proceedings or investigations.

 

×:Because audit logs contain sensitive data, only a specific subset of users should have access to them.

This is incorrect because only administrators and security personnel need to be able to view, modify, and delete audit trail information. Others cannot see this data and can rarely change or delete it. The use of digital signatures, message digest tools, and strong access controls can help ensure the integrity of the data. Its confidentiality can be protected with encryption and access control as needed, and it can be stored on write-once media to prevent data loss or tampering. Unauthorized access attempts to audit logs should be captured and reported.

 

×:Intruders may attempt to scrub logs to hide their activities.

If an intruder breaks into your home, do your best to leave no fingerprints or clues that can be used to link them to criminal activity. The same is true for computer fraud and illegal activity. Attackers often delete audit logs that hold this identifying information. In the text, deleting is described as scrubbing. Deleting this information may alert administrators to an alert or perceived security breach and prevent valuable data from being destroyed. Therefore, audit logs should be protected by strict access controls.

#81. It is not uncommon for business continuity plans to become outdated. What should you do to ensure that your plan does not become outdated?

〇:Business Continuity Processes Integrate Change Management Processes

Unfortunately, business continuity plans can quickly become outdated. An outdated BCP can give a company a false sense of security, which can be fatal if a disaster actually occurs. One of the simplest, most cost-effective, and process-efficient ways to keep your plan current is to incorporate it into your organization’s change management process. Are new applications, equipment, and services documented? Are updates and patches documented? The change management process should be updated to incorporate fields and triggers that alert the BCP team when significant changes occur and provide a means to update recovery documentation. Ensure that the BCP is kept up-to-date, and other measures include maintaining personnel evaluations of the plan and conducting regular training on using the plan, such as making business continuity part of all business decisions.

 

×:Update hardware, software, and application changes

Wrong because hardware, software, and application changes occur frequently; unless the BCP is part of a change management process, these changes are not included in the BCP. The BCP should be updated when changes to the environment occur. If it is not updated after a change, it is out of date.

 

×:Infrastructure and Environment Change Updates

Incorrect because infrastructure and environment changes occur frequently. Unless the BCP is part of a change management process, as with software, hardware, and application changes, infrastructure and environment changes are unlikely to result in a transition to the BCP.

 

×:Personnel changes

Incorrect, as the plan may become obsolete. It is not uncommon for BCPs to be abandoned when the person or persons responsible for maintenance leave the company. These responsibilities must be reassigned. To ensure this, maintenance responsibilities must be built into job descriptions and properly monitored.

#82. Which of the following is a straightforward inference as to why email spoofing was so easily carried out?

〇:SMTP lacks proper authentication mechanisms.

Email spoofing is easy to perform if the SMTP lacks proper authentication mechanisms. An attacker can spoof the sender address of an e-mail by sending a Telnet command to port 25 of the mail server. The spammer uses e-mail spoofing to prevent himself from being identified.

 

×:The administrator forgot to configure a setting that prevents inbound SMTP connections for non-functioning domains.

If it is spoofed, the email sender is also spoofed. This can happen even if you prevent inbound SMTP connections for a domain.

 

×:Technically abolished by keyword filtering.

Filtering is not very effective against spoofing. Therefore, even if it is technically obsolete, it is unlikely to be the cause.

 

×:The blacklist function is not technically reliable.

If an email is spoofed, the sender of the email is also spoofed. This can happen even if the filtering function is not reliable.

#83. The team should be involved in the implementation of the business continuity plan. Which team is responsible for initiating recovery of the original site?

〇:Salvage Teams

The BCP coordinator should understand the needs of the company and the types of teams that need to be developed and trained. Employees should be assigned to specific teams based on their knowledge and skill sets. Named leaders, each team must have members and the ability to direct their activities. These team leaders will be responsible not only for ensuring that team goals are met, but also for interacting with each other to ensure that each team is operating properly. The salvage team is responsible for initiating recovery of the original site. They are also responsible for backing up data from the alternate site and restoring it within the new facility, carefully terminating any unforeseen operations, and ensuring equipment and personnel are transported to the new facility.

 

×:Damage Assessment Team

The Damage Assessment Team is incorrect because it is responsible for determining the extent and severity of damage.

 

×:BCP Team

Wrong because the BCP team is responsible for creating and maintaining a business continuity plan.

 

×:Recovery Team

Wrong because the Recovery Team is responsible for getting an alternate site to work and to keep the environment functioning.

#84. Which of the following events occurs in a PKI environment?

〇:CA signs certificates.

A Certificate Authority (CA) is a trusted agency (or server) that maintains digital certificates. When a certificate is requested, the Registration Authority (RA) verifies the identity of the individual and passes the certificate request to the CA The CA creates the certificate, signs it, and maintains the certificate over its lifetime.

 

×:RA creates the certificate and CA signs it.

Incorrect because the RA does not create the certificate; the CA creates it and signs it; the RA performs authentication and registration tasks; establishes the RA, verifies the identity of the individual requesting the certificate, initiates the authentication process to the CA on behalf of the end user, and performs certificate life cycle RAs cannot issue certificates, but can act as a broker between the user and the CA When a user needs a new certificate, they make a request to the RA and the RA goes to the CA to verify all necessary identification before granting the request The RA verifies all necessary identification information before granting the request.

 

×:RA signs certificates.

The RA signs the certificate, which is incorrect because the RA does not sign the certificate; the CA signs the certificate; the RA verifies the user’s identifying information and then sends the certificate request to the CA.

 

×:The user signs the certificate.

Incorrect because the user has not signed the certificate; in a PKI environment, the user’s certificate is created and signed by the CA. The CA is a trusted third party that generates the user certificate holding its public key.

#85. Which of the following cannot be done by simply assigning a data classification level?

〇:Extraction of data from the database

In data classification, the data classification is used to specify which users have access to read and write data stored in the database, but it does not involve the extraction of data from the database. Therefore, the correct answer is “extraction of data from the database.

What is this? This is a question that you may think “What is this?” but you need to calmly analyze the classification of data and the manipulation of data. The more time you spend, the more tempted you are to give a difficult answer, but keeping calm is important in solving abstract problems.

 

×:Grouping hierarchically classified information

This is the primary activity of data classification.

 

×:Ensuring that non-confidential data is not unnecessarily protected

It is written in a complicated way, but it says that what does not need to be protected does not need the ability to be protected either.

 

×:Understanding the impact of data leakage

Although not directly, we may check the impact of a data breach in order to understand its importance in classifying data. Ka.

#86. We have confirmed that the program we developed is fine on the desk. However, we have been asked to actually run it. What kind of testing should be done?

〇:Dynamic Testing

Dynamic testing is testing that is performed by actually running the developed program. Compared to static testing, it is a practical test in which the program is actually run and checked. Therefore, the correct answer is “dynamic testing.

 

×:Static Testing

Static testing is testing that is performed without running the developed program.

 

×:White box testing

White box testing is a test to confirm the operation of a program after understanding the contents of the program.

 

×:Black box testing

Black box testing is testing to confirm that the program does not behave unexpectedly without understanding the contents of the program.

#87. The IT Security team has been asked to propose a mitigation strategy using the OSI reference model. Which of these would address the Layer 7 issue?

Application firewalls target Layer 7 of the OSI. The main advantage of an application firewall is its ability to understand specific applications and protocols. Packets are not decrypted until Layer 6, so Layer 7 can see the entire packet. Other firewalls can only inspect the packet, not the payload. It can detect if an unwanted application or service is trying to bypass the firewall by using a protocol on an allowed port, or if the protocol is being used in a malicious manner.

#88. Which of the following is most relevant in achieving the objective of securing all evidence and notating it as information to be presented to those who verify it?

〇:Control of the processing and distribution process

An important part of the digital forensic process is to maintain a proper chain of custody of evidence.

The question structure assumes Chain of Custody (Chain of Custody) from “the purpose of securing all evidence and notating it as information to be presented to those who verify it” and selects the one that comes closest to the definition.

 

×:Reasonable care

Wrong because reasonable care implies performing an activity that a reasonable person would be expected to perform under similar circumstances.

 

×:Investigation

Incorrect because investigation involves the proper collection of relevant data during the incident response process and includes analysis, interpretation, reaction, and recovery.

 

×:Motive, Opportunity, Means

Motive, Opportunity, and Means (MOM) is incorrect because it is a strategy used to understand why certain crimes were committed and by whom.

#89. Which of the following U.S. copyright laws make it a crime to attempt to infringe on access control measures to protect copyright?

〇:Digital Millennium Copyright Act

The Digital Millennium Copyright Act (DMCA) is a U.S. copyright law that makes it a crime, among other things, for technology to infringe upon the access control measures established to protect copyrighted material. Therefore, the correct answer is “Digital Millennium Copyright Act.

If you find a way to “unlock” a proprietary method of protecting an e-book, you can charge this act. Even if you do not share the actual copyrighted book with anyone, the specific law has been broken and you will be convicted.

 

×:COPPA

The Children’s Online Privacy Protection Act (COPPA) is a law that allows for the safe use of children’s sites on the Internet and prohibits children from being put at risk if they do not have any terms and conditions The law prohibits children from being endangered without any terms and conditions so that they can safely use the Internet for children.

 

×:Federal Privacy Act

There is no such law, but a close equivalent is the U.S. Federal Data Privacy Act. This would be a comprehensive privacy law at the federal level in the United States.

 

×:GDPR

The General Data Protection Regulation (GDPR) is a privacy law for EU citizens that is a stricter version of the Data Protection Directive.

#90. When attackers set up war dialing, what do they try to do?

War Dialing is the indiscriminate and repeated act of cracking dial-ups in search of dial-up lines, such as those for non-public internal networks. It automatically scans a list of telephone numbers, usually dialing all numbers in the local area code, and searches modems, computers, bulletin board systems, and fax machines.

#91. Which of the following is an incorrect description of IP telephony security?

〇:Softphones are safer than IP phones. 

IP softphones should be used with caution. A softphone is a software application that allows users to make calls via computer over the Internet. Replacing dedicated hardware, a softphone works like a traditional telephone. Skype is an example of a softphone application. Compared to hardware-based IP phones, softphones are more receptive to IP networks. However, softphones are no worse than other interactive Internet applications because they do not separate voice traffic from data, as IP phones do, and also because data-centric malware can more easily enter the network through softphones. network.

 

×:VoIP networks should be protected with the same security controls used on data networks.

The statement is incorrect because it correctly describes the security of an IP telephony network. an IP telephony network uses the same technology as a traditional IP network, which allows it to support voice applications. Therefore, IP telephony networks are susceptible to the same vulnerabilities as traditional IP networks and should be protected accordingly. This means that IP telephony networks should be designed to have adequate security.

 

×:As an endpoint, IP telephony can be a target of attack.

Incorrect because true: An IP phone on an IP telephony network is equivalent to a workstation on a data network in terms of vulnerability to attack. Thus, IP phones should be protected with many of the same security controls implemented on traditional workstations. For example, the default administrator password must be changed. Unnecessary remote access functions need to be disabled. Logging should be enabled and the firmware upgrade process should be secured.

 

×:The current Internet architecture in which voice is transmitted is more secure than physical phone lines.

True and therefore incorrect. In most cases, the current Internet architecture in which voice is transmitted is more secure than physical telephone lines. Physical phone lines provide a point-to-point connection, which is difficult to leverage over the software-based tunnels that make up the bulk of the Internet. This is an important factor to consider when protecting IP telephony networks because the network is now transmitting 2 valuable asset data and voice. It is not unusual for personal information, financial information, and other sensitive data to be spoken over the phone; intercepting this information over an IP telephony network is as easy as intercepting regular data. Currently voice traffic should also be encrypted.

#92. Which of the following attacks aims to bring down equipment by means of packets whose offsets have been tampered with?

〇:Teardrop

Teardrop is an attack to bring a system to a halt by forging the offset of IP packets when they are returned before splitting.

 

×:Fraggle attack

Fraggle attack is an attack that uses the CHARGEN function to generate an appropriate string.

 

×:CHARGEN attack

There is no attack with such a name.

 

×:War Driving

Wardriving is the act of driving around a city looking for vulnerable wireless LAN access points.

#93. Which of the following is not a network topology?

Matrix is not a network topology. Ring, mesh, and star are network topologies.

#94. Which of the following is an incorrect mapping of information security standards published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC)?

〇:ISO / IEC 27005 – Guidelines for Bodies Providing Audits and Certification of Information Security Management Systems

The ISO / IEC 27005 standard is a guideline for information security risk management. ISO / IEC 27005 is an international standard on how risk management should be implemented within the framework of an ISMS.

 

×:ISO / IEC 27002 – Code of practice for information security management

This is not correct because it is a code of practice for information security management. Therefore, it has the correct mapping. ISO / IEC 27002 provides best practice recommendations and guidelines for starting, implementing, or maintaining an ISMS.

 

×:ISO / IEC 27003 – ISMS Implementation Guidelines

This is incorrect as it is a guideline for ISMS implementation. Therefore, it has the correct mapping. Focuses on the key aspects necessary for the successful design and implementation of an ISMS according to ISO / IEC 27001:2005. It describes the ISMS specification and design process from its inception to the creation of an implementation plan.

 

×:ISO / IEC 27004 – Guidelines for Information Security Management Measurement and Metrics Framework

This is incorrect because it is a guideline for an information security management measurement and metrics framework. Therefore, it has the correct mapping. It provides guidance on the development and use of measures to assess the effectiveness of an ISMS and a group of controls or controls, as specified in ISO / IEC 27001.

#95. Which of the following backup types does NOT clear the archive bit of the Windows system?

Archive bits are those that have been updated since the previous backup point in time. Full backups are full backups, so there is no need to be aware of where changes have occurred. Incremental backups also do not require awareness of change points because the backup portion is predetermined. Therefore, both clear the archive bit. However, differential backups do not clear the archive bit because only the changed part is known to be backed up.

#96. Jim is a sales representative and the data owner of the sales department. Which of the following is not the responsibility of Jim, the data owner?

〇:Verifying Data Availability

The responsibility for verifying data availability is the sole responsibility that does not belong to the data (information) owner. Rather, it is the responsibility of the data (information) controller. The data controller is also responsible for maintaining and protecting the data in accordance with the data owner’s instructions. This includes performing regular backups of data, restoring data from backup media, maintaining records of activities, and enforcing information security and data protection requirements in company policies, guidelines, and standards. Data owners work at a higher level than data managers. The data owner basically says, “This is the level of integrity, availability, and confidentiality you need to provide. Please do it now”. The data administrator is executing these permissions and following up on the installed controls to ensure they are working properly.

 

×:Assigning Information Classification

Incorrect as you are asking if Jim is not responsible for the assignment of information classifications because as the data owner, Jim is responsible for the assignment of information classifications.

 

×:Determining how to protect data

Incorrect because the data owner, such as Jim, is responsible for determining how the information is protected. The data owner has organizational responsibility for data protection and is liable for any negligence with respect to protecting the organization’s information assets. This means that Jim needs to decide how to protect the information and ensure that the data controller (a role usually occupied by IT or security) is implementing these decisions.

 

×:Determining how long to retain data

This is incorrect because the decision of how long to retain data is the responsibility of the data owner. The data owner is also responsible for determining who can access the information and ensuring that the appropriate access rights are used. He may approve access requests himself or delegate that function to the business unit manager. The business unit manager approves the request based on the user access criteria defined by the data owner.

#97. Which of the following is not an ethical item in the IAB (Internet Activities Board) Ethics for the Proper Use of Internet Resources?

This is a “non-ethics item” question.

A statement is made by the Internet Activities Board (IAB) to those who use the Internet about the correct use of Internet resources.

  • Attempting to obtain unauthorized access to Internet resources.
  • Disrupting the intended use of the Internet.
  • Wasting resources (people, capabilities, and computers) through such activities.
  • Destroying the integrity of computer-based information.
  • Violating the privacy of users.

#98. John provides a weekly report to the manager outlining security incidents and mitigation procedures. If there is no incident information to put on the report, what action should he take?

〇:Send a report labeled “No output”.

If there is nothing to report (nothing to report), you need to make sure the manager is aware that the report has no information and is not only to be held accountable.

 

×:Send an email notifying the manager that there is nothing to report.

It is not appropriate to suddenly keep a record of the report by e-mail, since the report is normally scheduled to be reported in the operation. Realistically, wouldn’t you be more endearing to your manager if you communicated with him or her every step of the way? No, I am not asking you to do that.

 

×:Re-submit last week’s report and submit the date of last week’s report as this week’s date.

Delivering last week’s report does not express that nothing was reported this week.

 

×:Nothing.

You are required to report that nothing happened.

#99. Management support is critical to the success of a business continuity plan. Which of the following is most important to provide to management in order to obtain support?

〇:Business Case

The most important part of establishing and maintaining a current continuity plan is management support. Management may need to be convinced of the need for such a plan. Therefore, a business case is needed to obtain this support. The business case should include current vulnerabilities, legal obligations, current status of the recovery plan, and recommendations. Management is generally most interested in cost-benefit issues, so preliminary figures can be gathered and potential losses estimated. Decisions about how a company should recover are business decisions and should always be treated as such.

 

×:Business Impact Analysis

Incorrect because the Business Impact Analysis (BIA) was conducted after the BCP team gained management’s support for its efforts. A BIA is conducted to identify areas of greatest financial or operational loss in the event of a disaster or disruption. It identifies the company’s critical systems required for survival and estimates the amount of downtime the company can tolerate as a result of a disaster or disruption.

 

×:Risk Analysis

Incorrect, as this is a method of identifying risks and assessing the potential damage that could be caused to justify security protection measures. In the context of BCP, risk analysis methods should be used in a BIA to identify which processes, devices, or operations are critical and should be recovered first.

 

×:Threat reports

The answer is wrong because it is unintended. However, it is important for management to understand what the actual threats are to the enterprise, the consequences of those threats, and the potential loss value for each threat. Without this understanding, management pays lip service to continuity planning and in some cases may be worse than if it did not plan because of the false awareness of security it creates.

#100. Which of the following is a critical first step in disaster recovery and emergency response planning?

〇:Completing the Business Impact Analysis

Of the steps listed in this question, completing the Business Impact Analysis is the highest priority. The BIA is essential in determining the most critical business functions and identifying the threats associated with them. Qualitative and quantitative data must be collected, analyzed, interpreted, and presented to management.

 

×:Test and Drill Plan

Test and drill is wrong because it is part of the last step in disaster recovery and contingency planning. Because the environment is constantly changing, it is important to test your business continuity plan on a regular basis. Testing and disaster recovery drills and exercises should be performed at least once a year. The exercises should be done in sections or at specific times that require logistical planning, as most firms cannot afford these exercises to disrupt production or productivity.

 

×:Determining alternatives for off-site backup facilities

This is incorrect because it is part of the contingency strategy that is done in the middle of the disaster recovery and contingency planning process. In the event of a major disaster, an alternate off-site backup capability is required. Typically, contracts are established with third-party vendors to provide such services. The client pays a monthly fee to retain the right to use the facility when needed and then pays an activation fee when they need to use that facility.

 

×:Organize and prepare related documentation

This is incorrect because the relevant documentation is organized and created around the time the disaster recovery and contingency planning process is completed. Procedures should be documented. This is because time-consuming schedules are confusing when they are actually needed. Documentation should include information on how to install images, configure the operating system and server, and install utilities and proprietary software. Other documentation should include call trees and contact information for specific vendors, emergency agencies, off-site facilities, etc.
