The IS auditor is evaluating the systems development processes and practices of an organization to ensure alignment with information security and privacy architectures. What should the IS auditor do FIRST in this evaluation?

• A.A. Conduct a design review to identify potential security and privacy vulnerabilities
• B.B. Perform regression testing to ensure that changes to the system have not introduced new security risks
• C.C. Assess the organization's systems development life cycle (SDLC) to ensure it is properly defined and aligned with the organization's information security and privacy architectures
• D.D. Develop a plan to conduct regular security assessments and penetration testing

Why: Evaluate systems development processes and practices The correct answer is to assess the control assessments conducted during the SDLC to identify deficiencies and areas for improvement. This is because deficiencies identified early in the SDLC can be resolved in a more cost-effective manner (NIST SP 800-37r2).

What is the primary benefit of conducting security risk assessments during the systems development life cycle (SDLC)?

• A.To identify potential security risks and develop mitigation strategies
• B.To evaluate system performance and optimize resource allocation
• C.To develop a plan to conduct regular security audits and compliance checks
• D.To implement a robust planning process to manage project timelines and budgets

Why: Evaluate systems development processes and practices The correct answer is to identify potential security risks and develop mitigation strategies. This is because conducting assessments during the SDLC can help identify potential security risks and develop mitigation strategies (NIST SP 800-37r2).

The IS auditor is reviewing the systems maintenance processes of an organization and finds that the organization is not conducting regular performance and security assessments. What should the IS auditor recommend to ensure that the organization's systems maintenance processes are effective?

• A.A. Conduct a one-time system assessment to identify performance and security issues
• B.B. Implement a continuous monitoring strategy to identify and address performance and security weaknesses
• C.C. Develop a plan to provide security awareness training to users and operators
• D.D. Update the organization's security policy to include stricter penalties for bypassing security controls

Why: Evaluate systems maintenance processes and practices The correct answer is to implement a continuous monitoring strategy to identify and address security control weaknesses. This is because continuous monitoring can help ensure that security controls are operating as intended and identify areas for improvement, which is a key aspect of maintaining operational assurance (NIST SP 800-12r1).

What should the IS auditor do FIRST when evaluating the adequacy of a system's development process?

• A.Conduct a design review to identify potential security vulnerabilities
• B.Perform regression testing to ensure that changes have not introduced new issues
• C.Assess the system's compliance with established information security and privacy architectures
• D.Review the system's documentation to ensure that it is complete and up-to-date

Why: Evaluate systems development processes and practices to ensure security and privacy The correct answer is to assess the system's compliance with established information security and privacy architectures, as this is a critical step in evaluating the adequacy of a system's development process, as stated in NIST SP 800-37r2.

What should the IS auditor do FIRST when evaluating the change management process for a new cloud-based system?

• A.Review the change management policy and procedures to ensure they are up-to-date and relevant
• B.Evaluate the training and awareness programs for end-users and IT staff on the new cloud-based system
• C.Assess the impact of the new cloud-based system on existing business processes and procedures
• D.Analyze the configuration management and version control processes for the new cloud-based system

Why: Evaluate systems maintenance processes and practices by reviewing the change management policy and procedures The IS auditor should first review the change management policy and procedures to ensure they are up-to-date and relevant. This will provide a foundation for further evaluation of the change management process and help identify any gaps or weaknesses.
