CISA Practice Question: Information Systems Acquisition, Development, and Implementation
An IS auditor is reviewing an emergency change that was implemented to fix a critical security vulnerability. Which of the following post-implementation controls is MOST important to ensure the change was properly managed?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A post-implementation review was performed by the Change Advisory Board (CAB)
Emergency changes bypass normal CAB approval, so it is critical to document the change and have it retrospectively reviewed by the CAB to ensure proper governance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The change request included a rollback plan
Why it's wrong here
A rollback plan is important but not the most critical post-implementation control for governance.
- ✗
The change was tested in a production-like environment before deployment
Why it's wrong here
Testing is important, but due to the emergency nature, some testing may be limited; retrospective review is key.
- ✓
A post-implementation review was performed by the Change Advisory Board (CAB)
Why this is correct
Retrospective CAB review ensures that the emergency change is justified and properly documented, maintaining control over the change process.
- ✗
The change was documented and approved by the change manager after implementation
Why it's wrong here
Documentation is necessary but CAB review provides broader oversight.
