CAS-004 Practice Question: During a risk assessment, a residual risk is…
During a risk assessment, a residual risk is identified as high. What should be the NEXT step?
⚠ Common exam trap
In CASP+, a common misconception is that residual risk is automatically acceptable or can be ignored, when in fact it must be actively managed and reduced if it exceeds the defined risk appetite.

Correct answer & explanation
✓
Implement additional controls to reduce the risk to an acceptable level
When residual risk remains high after applying controls, the correct next step is to implement additional controls to reduce it to an acceptable level. This aligns with the risk treatment process in NIST SP 800-37, where residual risk must be evaluated against the organization's risk appetite and, if unacceptable, further mitigation is required. Simply transferring, ignoring, or accepting a high residual risk without analysis violates governance principles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Transfer the risk to a third party
Why it's wrong here
Transfer may be considered but not automatically the next step.
- ✓
Implement additional controls to reduce the risk to an acceptable level
Why this is correct
The next step is to apply additional controls to lower residual risk.
- ✗
Ignore the risk because it is residual
Why it's wrong here
Ignoring high residual risk is not acceptable risk management.
- ✗
Accept the residual risk as is
Why it's wrong here
High residual risk should not be accepted without further mitigation.
