CRISC Risk Response and Mitigation Practice Question
A bank implements a new transaction monitoring system to detect fraudulent activities. After six months, the system has a high false positive rate, causing analysts to miss real threats. Which of the following is the BEST way to address this risk?
⚠ Common exam trap
It's easy for candidates to choose D (hire more analysts) because it seems like a direct solution to alert overload, but it fails to address the system's inefficiency and is not a sustainable risk response per CRISC principles.
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
✓
Tune the system to reduce false positives
B is correct because tuning the system involves adjusting detection thresholds, rules, or machine learning models to reduce false positives while maintaining sensitivity to actual fraud. This directly addresses the root cause—poorly calibrated detection logic—without sacrificing the system's primary function or incurring unsustainable costs.
