Click on the arrows to vote for the correct answer
A. B. C. D.D.
Change management is a process used by organizations to manage changes to their IT systems and applications in a controlled and systematic manner. Information security is an essential consideration in change management, as changes to an IT system can introduce new security risks or vulnerabilities. Therefore, it is important to ensure that information security is adequately addressed in the change management process.
Of the options provided, reviewing changes from a security perspective provides the greatest assurance that information security is addressed in change management. Here's why:
A. Performing a security audit on changes: While performing a security audit on changes can help identify potential security issues, it does not necessarily provide assurance that information security is addressed in change management. A security audit may only be performed periodically, whereas change management is an ongoing process that requires continuous attention to information security.
B. Providing security training for change advisory board: Providing security training for the change advisory board (CAB) can help increase their awareness of security issues, but it does not necessarily ensure that information security is addressed in the change management process. The CAB is responsible for reviewing proposed changes and making recommendations, but they may not have the expertise or authority to enforce security requirements.
C. Requiring senior management sign-off on change management: Requiring senior management sign-off on change management can help ensure that changes are approved by authorized personnel and aligned with organizational goals. However, it does not provide assurance that information security is addressed in the change management process. Senior management may not have the necessary technical knowledge to evaluate security implications of proposed changes.
D. Reviewing changes from a security perspective: Reviewing changes from a security perspective provides the greatest assurance that information security is addressed in change management. This involves evaluating proposed changes to identify potential security risks or vulnerabilities and ensuring that appropriate security controls are in place to mitigate them. By reviewing changes from a security perspective, organizations can ensure that information security is considered throughout the change management process, from initial proposal to final implementation.
In summary, while all the options provided may help address information security in change management, reviewing changes from a security perspective provides the greatest assurance that information security is adequately addressed.
