CS0-003 Risk Acceptance Practice Question
A legacy system cannot be patched because the vendor no longer supports the application. What should the vulnerability manager request? For validation, Which action should be taken before closing or downgrading the finding?
⚠ Common exam trap
The CS0-004 exam often tests the misconception that 'no patch available' means the vulnerability can be closed as 'fixed' or that compensating controls alone are sufficient without formal documentation and a plan.

Correct answer & explanation
✓
Documented risk acceptance with compensating controls and a migration/remediation plan
When a legacy system cannot be patched due to vendor end-of-life, the vulnerability manager must formally accept the risk by documenting the risk acceptance, implementing compensating controls (e.g., network segmentation, host-based firewall rules, or application whitelisting), and creating a migration or remediation plan to eventually retire or replace the system. This aligns with the NIST SP 800-53 risk management framework and ensures auditability.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Give all users local admin rights
Why it's wrong here
Extra privileges increase risk.
- ✗
Mark the vulnerability as fixed
Why it's wrong here
It is not fixed if the vulnerable condition remains.
- ✓
Documented risk acceptance with compensating controls and a migration/remediation plan
Why this is correct
Unsupported systems need formal exception handling, mitigation, ownership, and an exit path.
- ✗
Remove the system from future reports
Why it's wrong here
Suppressing visibility hides unmanaged risk.
