CRISC Practice Question: Has implemented a continuous monitoring solution…
An organization has implemented a continuous monitoring solution for its critical applications. The IT team reports that the monitoring tool generates a high volume of false positives. What is the BEST course of action?
⚠ Common exam trap
The CRISC exam often tests the misconception that increasing resources (team size) or adding more controls is the best response to monitoring inefficiency, when in fact tuning existing controls is the most effective and risk-appropriate action.

Correct answer & explanation
✓
Refine the monitoring rules and thresholds to reduce false positives.
Refining monitoring rules and thresholds directly addresses the root cause of false positives by tuning the detection logic to better match actual risk conditions. This aligns with the CRISC principle of optimizing control efficiency rather than accepting or compensating for excessive noise. For example, adjusting anomaly detection thresholds in a SIEM like Splunk or QRadar can reduce alert volume without sacrificing coverage of genuine threats.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Refine the monitoring rules and thresholds to reduce false positives.
Why this is correct
Tuning the tool reduces noise and enhances monitoring effectiveness.
- ✗
Disable the monitoring for applications that generate the most false positives.
Why it's wrong here
Disabling monitoring increases risk.
- ✗
Increase the size of the monitoring team to handle the alerts.
Why it's wrong here
More staff does not solve the false positive issue.
- ✗
Implement additional detective controls for all false positive alerts.
Why it's wrong here
Adding controls for false positives is inefficient.
