CRISC Risk Response and Reporting Practice Question
During a quarterly control effectiveness test, internal audit finds that a detective control missed 15% of security incidents. The control owner claims this is within the acceptable error rate of 20%. However, the risk practitioner notes that the missed incidents were high-severity. What should the risk practitioner do?
⚠ Common exam trap
The CRISC exam often tests the misconception that meeting a quantitative KCI threshold automatically means a control is effective, without considering the qualitative severity of the incidents missed.

Correct answer & explanation
✓
Escalate the findings to senior management with a recommendation to enhance the control
The risk practitioner should escalate the findings to senior management with a recommendation to enhance the control because the detective control's failure to detect 15% of incidents, while within the 20% acceptable error rate, specifically missed high-severity incidents. High-severity incidents pose a disproportionate risk to the organization, and a control that fails to detect them is not effective in mitigating critical risks, regardless of meeting a generic threshold. Escalation ensures that management is aware of the residual risk and can authorize appropriate enhancements, such as tuning the control's detection logic or implementing additional monitoring for high-severity events.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Accept the control as effective since it is within the threshold
Why it's wrong here
The threshold may not be appropriate for high-severity incidents; acceptance could overlook significant risk.
- ✓
Escalate the findings to senior management with a recommendation to enhance the control
Why this is correct
Escalation ensures that the risk associated with missed high-severity incidents is communicated to decision-makers.
- ✗
Implement a compensating control to cover high-severity incidents
Why it's wrong here
This may be a solution, but the first step should be to escalate the issue for proper analysis.
- ✗
Recommend revising the KCI threshold to include severity weighting
Why it's wrong here
While revising the threshold might be a long-term action, immediate escalation is needed.
