The best solution to secure the VoIP phones and prevent unauthorized phone usage is to use phone locking software to enforce usage and PIN policies. Phone locking software can restrict the access to the phone features and functions based on the user's PIN, role, or location. Phone locking software can also enforce policies such as PIN expiration, PIN complexity, PIN history, and PIN lockout. Phone locking software can also generate logs and reports of the phone usage and activity. This way, the phone locking software can enhance the security, accountability, and compliance of the VoIP phone system . The other solutions are not as effective, because they rely on the user or the administrator to change the PIN regularly, which may not be feasible, consistent, or secure. Implementing call detail records (CDR) reports to track usage is a good practice, but it does not prevent unauthorized phone usage in the first place.Reference: [CISSP CBK, Fifth Edition, Chapter 4, page 377]; [2024 Pass4itsure CISSP Dumps, Question 8].

Retaining system logs for six months or longer can be valuable for forensics and incident response activities. System logs are records of events that occur on a system, such as user actions, system errors, security alerts, network traffic, etc. System logs can provide useful evidence and information for investigating and analyzing security incidents, such as the source, scope, impact, and timeline of the incident, as well as the potential vulnerabilities, threats, and attackers involved.System logs can also help with incident recovery and remediation, as well as with improving security controls and policies12Reference:CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7: Security Operations, p. 437;Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 7: Security Operations, p. 849.

Automated application security testing tools are software tools that can scan, analyze, and test the code of an application for vulnerabilities, errors, or flaws. The primary advantage of using these tools is that they can test large amounts of code using fewer resources, such as time, money, and human effort, than manual testing. This can improve the efficiency, effectiveness, and coverage of the testing process. The application can be protected in the production environment, the application will fail less when tested using these tools, and detailed testing of code functions can be performed are all possible outcomes of using automated application security testing tools, but they are not the primary advantage of using them.Reference:CISSP All-in-One Exam Guide, Eighth Edition, Chapter 8, Software Development Security, page 1017.Official (ISC)2 CISSP CBK Reference, Fifth Edition, Chapter 8, Software Development Security, page 1039.

A data steward is responsible for ensuring the quality, consistency, and usability of data within an enterprise data lake. This includes defining the business context, purpose, and value of the data, as well as ensuring that the data is properly documented, classified, and governed. A data steward also facilitates the communication and collaboration between data producers, consumers, and owners within the organization.Reference:

The best reason to include supply chain risks in a corporate risk register is that risk registers classify and categorize risk and allow risks to be compared to corporate risk appetite. A risk register is a tool for documenting and managing risks across an organization. A risk register typically includes information such as risk identification, risk analysis, risk evaluation, risk treatment, risk monitoring and review. By including supply chain risks in a risk register, an organization can identify the sources and impacts of the risks, assess their likelihood and severity, evaluate their acceptability, implement appropriate controls, and monitor their effectiveness. A risk register can also help an organization to align its supply chain risk management with its overall risk management strategy and objectives. A risk register does not help fund corporate SCRM systems, as it is not a budgeting tool. A risk register does not illustrate residual risk across the company, as it does not show the risk level after applying controls. A risk register does not allow for the transfer of risk to third parties, as it does not assign risk ownership or responsibility.Reference:Official (ISC)2 Guide to the CISSP CBK, Fifth Edition, Chapter 1: Security and Risk Management, page 72.
