A tamper seal is a device or material that is attached to a computer system’s case to indicate whether the case has been opened or tampered with. The main purpose of placing a tamper seal on a computer system’s case is to detect efforts to open the case, as the seal will be broken or damaged if someone tries to access the internal components of the system. This can help deter unauthorized access, prevent physical damage or theft, and provide evidence for forensic investigation. Raising security awareness is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of reminding users of the importance of physical security. Expediting physical auditing is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of simplifying the process of checking the integrity of the system. Making it difficult to steal internal components is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of increasing the effort and risk of the attacker. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5: Security Architecture and Engineering, p. 409. Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 3: Security Architecture and Engineering, p. 298.

Single sign-on (SSO) is a system that allows a user to log in and access multiple related servers and applications with a single authentication process. SSO simplifies the user experience and reduces the administrative overhead of managing multiple credentials. SSO can be implemented using various technologies, such as Kerberos, Security Assertion Markup Language (SAML), or OAuth. Remote Desktop Protocol (RDP) is a protocol that allows a user to remotely access and control another computer over a network. Federated identity management (FIM) is a system that allows a user to use the same identity and credentials across multiple organizations or domains that have established a trust relationship. Multi-factor authentication (MFA) is a method of authentication that requires two or more independent factors to verify the identity of a user, such as something you know, something you have, or something you are.

The regulatory scheme that defines how weapons are exchanged between the signatories, and that also addresses cyber weapons, including malicious software, Command and Control (C2) software, and internet surveillance software, is the Wassenaar arrangement. The Wassenaar arrangement is an international multilateral export control regime that aims to promote transparency and responsibility in the transfer of conventional arms and dual-use goods and technologies, which are goods and technologies that can have both civilian and military applications. The Wassenaar arrangement also covers cyber weapons, such as malicious software, C2 software, and internet surveillance software, which are goods and technologies that can be used to conduct cyberattacks or cyber espionage. The Wassenaar arrangement requires the signatories to report and control the export of the cyber weapons, and to prevent the proliferation or misuse of the cyber weapons . References: [CISSP CBK, Fifth Edition, Chapter 2, page 95]; [CISSP Practice Exam – FREE 20 Questions and Answers, Question 18].

Separation of duties is a security principle that requires that no single person or entity should be able to perform two or more conflicting or sensitive functions that could result in fraud, misuse, or compromise of the system or data. Separation of duties analysis is the process of identifying and resolving such conflicts of interest or incompatible functions. A manager who discovers that a single user account has been assigned two conflicting sensitive user functions, such as approving and recording transactions, has most likely performed a separation of duties analysis. Security control assessment, network access control review, and federated identity management evaluation are not directly related to the identification of conflicting user functions. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 1, Security Governance Through Principles and Policies, page 24. Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 1, Security and Risk Management, page 42.

The role that is responsible for determining who has a need for the information when developing the entitlement review process is the data owner. The data owner is a person or entity that has the authority and accountability for the creation, classification, usage, and protection of the data or information within an organization. The data owner is responsible for determining who has a need for the information when developing the entitlement review process, by defining and approving the access rights and privileges of the data or information, based on the business needs and security requirements of the organization and the stakeholders. The entitlement review process is a process that verifies and validates the access rights and privileges of the data or information, to ensure that they are appropriate, necessary, and compliant with the organization’s policies and standards. The entitlement review process can help to prevent or reduce the unauthorized, excessive, or inappropriate access to the data or information, as well as to identify and resolve any access issues or anomalies. The data owner is responsible for determining who has a need for the information when developing the entitlement review process, by ensuring that the access rights and privileges of the data or information are consistent and compatible with the data owner’s objectives and expectations, as well as with the data owner’s roles and responsibilities. Data Custodian, Database Administrator, or Information Technology (IT) Director are not the roles that are responsible for determining who has a need for the information when developing the entitlement review process, as they are more related to the implementation, maintenance, or management aspects of the data or information, rather than the authority or accountability aspects of the data or information. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5: Identity and Access Management, page 308; CISSP Official (ISC)2 Practice Tests, Third Edition, Domain 5: Identity and Access Management, Question 5.9, page 220.

A log source is a device or system that generates and sends data to a security information and event management (SIEM) system, such as logs, alerts, or events. A log source that has stopped sending data would be considered an incident if reported by a SIEM system, as this could indicate a malfunction, a compromise, or a denial of service attack on the log source. A SIEM system relies on the data from the log sources to provide a comprehensive and accurate view of the security posture and events of the organization. An administrator logging in on a server through a virtual private network (VPN) would not be considered an incident, as this is a legitimate and authorized activity. A web resource reporting a 404 error would not be considered an incident, as this is a common and benign error that indicates that the requested resource was not found on the server. A firewall logging a connection between a client on the Internet and a web server using Transmission Control Protocol (TCP) on port 80 would not be considered an incident, as this is a normal and expected traffic for web browsing.

Applying the latest vendor patches and updates is the first action that will lock down the system and minimize the risk of an attack, because it will fix any known vulnerabilities or bugs that could be exploited by attackers. Installing an antivirus on the server, running a vulnerability scanner, and reviewing access controls are also important security measures, but they are not the first actions to take. An antivirus may not detect all types of malware, a vulnerability scanner may not find all the flaws in the system, and access controls may not prevent all unauthorized access12. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 10, page 883; CISSP Practice Exam – FREE 20 Questions and Answers, Question 8.

The key findings section of the assessment report is where the separate vulnerabilities, weaknesses, and gaps identified during the assessment are presented and prioritized. This section should provide a clear and concise summary of the most significant issues that need to be addressed by the organization. The other options are not correct. The executive summary with full details is a contradiction, as the executive summary should only provide a brief overview of the assessment objectives, scope, methodology, and results. The risk review section is where the risks associated with the identified vulnerabilities, weaknesses, and gaps are analyzed and evaluated. The findings definition section is not a standard section of the assessment report, although it may be included as part of the introduction or background to explain the terminology and criteria used for the assessment. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 6: Security Assessment and Testing, page 715. Official (ISC)2 CISSP CBK Reference, Fifth Edition, Chapter 6: Security Assessment and Testing, page 713.

Runtime application self-protection (RASP) is a technology that can be used to monitor and dynamically respond to potential threats on web applications. RASP is a software component that is integrated into the web application or the runtime environment, and it analyzes the behavior and the context of the application and the requests. RASP can detect and prevent attacks such as SQL injection, cross-site scripting, or buffer overflow, by blocking or modifying the malicious requests or responses. RASP can also provide alerts and logs for the security team or the developers. The other options are not correct. Security Assertion Markup Language (SAML) is a standard that enables single sign-on (SSO) and federated identity management for web applications, but it does not monitor or respond to threats. Web application vulnerability scanners are tools that scan web applications for common vulnerabilities and misconfigurations, but they do not provide real-time protection or response. Field-level tokenization is a technique that replaces sensitive data fields with random tokens, and it can reduce the exposure or the impact of a data breach, but it does not monitor or respond to threats. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 4: Security Architecture and Engineering, page 512. Official (ISC)2 CISSP CBK Reference, Fifth Edition, Chapter 4: Security Architecture and Engineering, page 513.

 Build and test is a subsection that is recommended as part of the change management process. Change management is a process that ensures that any changes to the organization’s information systems and assets are controlled, documented, and approved, and that they do not adversely affect the security and the performance of the systems and the assets. Change management is based on the principles of directive controls, which are the policies and the procedures that guide and regulate the change management process. One of the subsections of the change management process is build and test, which involves developing and verifying the proposed changes before implementing them in the production environment. Build and test can help ensure that the changes are consistent with the design specifications, that they meet the security and the functional requirements, and that they do not introduce any errors, flaws, or vulnerabilities. Build and test can also help evaluate the impact and the benefits of the changes, and identify and resolve any issues or conflicts that may arise during the change process. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 8: Software Development Security, page 467. Free daily CISSP practice questions, Question

The primary issue when analyzing detailed log information is that timely review of the data is potentially difficult. Log information is the record of events or activities that occur on a system or a network. Log information can provide valuable insights into the performance, security, and usage of the system or network. However, log information can also be voluminous, complex, and heterogeneous, making it challenging to review and analyze in a timely manner. Without proper tools and techniques, log analysis can be time-consuming, resource-intensive, and error-prone. The other options are not the primary issue when analyzing detailed log information. Logs may be unavailable when required, but this is more of a log management issue than a log analysis issue. Most systems and applications do support logging, but the level and quality of logging may vary. Logs do provide sufficient details of system and individual activities, but the details may not be easy to interpret or correlate. References: Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 7: Security Operations, p. 881-882; CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7: Security Operations, p. 467-468.

A disadvantage of an application filtering firewall is that it can lead to performance degradation due to the rules applied. An application filtering firewall is a type of firewall that inspects the content and context of the data packets at the application layer of the OSI model. It can block or allow traffic based on the application protocol, the source and destination addresses, the user identity, the time of day, and other criteria. An application filtering firewall provides a high level of security and control, but it also requires more processing power and memory than other types of firewalls. This can result in slower network performance and increased latency56. References: 5: Application Layer Filtering (ALF): What is it and How does it Fit into your Security Plan?76: Different types of Firewalls: Their advantages and disadvantages

A fundamental objective in handling an incident is to restore control of the affected systems as soon as possible. An incident is an event or a situation that violates or threatens the security, confidentiality, integrity, or availability of an organization’s information assets or resources3. Handling an incident is the process of responding to, containing, analyzing, recovering from, and reporting on an incident, with the aim of minimizing the impact and preventing the recurrence of the incident. Restoring control of the affected systems is a crucial objective in handling an incident, as it can help to resume the normal operations, services, and functions of the organization, and to mitigate the damage or loss caused by the incident. Confiscating the suspect’s computers, prosecuting the attacker, and performing full backups of the system are not fundamental objectives in handling an incident, as they are more related to the investigation, legal, or recovery aspects of the incident, which may not be as urgent or essential as restoring control of the affected systems. References: 3: Official (ISC)2 CISSP CBK Reference, 5th Edition, Chapter 7, page 375. : CISSP All-in-One Exam Guide, Eighth Edition, Chapter 9, page 559.

A signed and encrypted e-mail provides confidentiality by preventing unauthorized access to the message content, non-repudiation by verifying the identity and integrity of the sender, and authentication by ensuring that the message is from the claimed source. Authorization is not a benefit of a signed and encrypted e-mail, as it refers to the process of granting or denying access to resources based on predefined rules.

The most important factor in designing a biometric access system if it is essential that no one other than authorized individuals are admitted is the False Acceptance Rate (FAR). FAR is the probability that a biometric system will incorrectly accept an unauthorized user or reject an authorized user2. FAR is a measure of the security or accuracy of the biometric system, and it should be as low as possible to prevent unauthorized access. False Rejection Rate (FRR), Crossover Error Rate (CER), and Rejection Error Rate are not as important as FAR, as they are related to the usability or convenience of the biometric system, rather than the security. FRR is the probability that a biometric system will incorrectly reject an authorized user or accept an unauthorized user. CER is the point where FAR and FRR are equal, and it is used to compare the performance of different biometric systems. Rejection Error Rate is the probability that a biometric system will fail to capture or process a biometric sample. References: 2: CISSP For Dummies, 7th Edition, Chapter 4, page 95.
