CRISC Practice Question: The risk manager at a financial institution that…
You are the risk manager at a financial institution that processes online transactions. The organization relies on a legacy system for transaction authorization, which is monitored via manual log reviews performed weekly by a junior analyst. Recently, the internal audit team identified that several unauthorized transactions were not detected for over two weeks. The logs showed that the authorization control failed intermittently due to a known software bug, but the bug had been documented in the risk register with a low residual risk rating. The CRO asks you to recommend the most effective improvement to the control monitoring process. Which of the following would be the BEST course of action?
⚠ Common exam trap
Test-takers frequently choose to increase review frequency (Option B) because it seems like a direct improvement, but they fail to recognize that manual reviews, regardless of frequency, still suffer from human delay and cannot match the immediacy of automated monitoring for intermittent control failures.

Correct answer & explanation
✓
Implement an automated real-time monitoring tool that alerts on authorization failures.
Implementing an automated real-time monitoring tool that alerts on authorization failures directly addresses the root cause: the detection delay caused by manual weekly log reviews. Unlike manual reviews, automated monitoring provides immediate notification of control failures, enabling rapid response to intermittent software bugs and reducing the window of exposure for unauthorized transactions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement an automated real-time monitoring tool that alerts on authorization failures.
Why this is correct
Automated monitoring provides immediate detection and reduces reliance on manual reviews.
- ✗
Increase the frequency of log reviews to daily.
Why it's wrong here
Daily manual reviews still have delays and may miss intermittent failures.
- ✗
Update the risk register to increase the residual risk rating for the bug.
Why it's wrong here
Updating the rating does not improve detection or control effectiveness.
- ✗
Retrain the junior analyst on log analysis techniques.
Why it's wrong here
Training does not address the intermittent system bug or detection timeliness.
