The answer is deploying user behavior analytics (UBA) tools for automated anomaly detection. This is the most effective recommendation because UBA directly addresses the core problem of improving log review efficiency by automating the detection of anomalous access patterns, which eliminates the bottleneck of manual sampling and drastically reduces detection time from weeks to near-real-time. On the CRISC exam, this scenario tests your understanding of how to align monitoring controls with a low risk appetite for unauthorized access; the common trap is choosing to increase the sample size or hire more staff, which only treats the symptom of workload rather than the root cause of inefficient review. A key memory tip is to think of UBA as a force multiplier that shifts log review from a reactive, manual chore to a proactive, automated intelligence function, directly supporting the organization’s need for timely detection under strict regulatory requirements.
CRISC Risk and Control Monitoring and Reporting Practice Question
This CRISC practice question tests your understanding of risk and control monitoring and reporting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A healthcare organization is subject to strict regulatory requirements regarding patient data privacy. The organization has a control that requires all access to patient records to be logged and reviewed weekly by the compliance team. The review is currently performed manually by sampling 10% of the logs. The compliance team reports that the review takes 20 hours per week and they are often unable to complete it on time. As a result, some suspicious access patterns are detected weeks after they occur. The risk manager needs to propose an improvement to the monitoring process. The organization's risk appetite for undetected unauthorized access is very low. Which of the following is the MOST effective recommendation?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy user behavior analytics (UBA) tools for automated anomaly detection.
Option B is correct because implementing user behavior analytics (UBA) automates the detection of anomalous access patterns, reducing manual effort and improving detection speed. Option A is wrong increasing sample size does not address the timeliness issue. Option C is wrong hiring more staff is costly and may not scale. Option D is wrong reducing frequency would delay detection further, increasing risk.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Reduce the review frequency to bi-weekly to free up time.
Why it's wrong here
Less frequent reviews increase the window for undetected access.
✗
Hire additional staff to perform the manual reviews.
Why it's wrong here
Hiring increases cost and still relies on manual sampling.
✓
Deploy user behavior analytics (UBA) tools for automated anomaly detection.
Why this is correct
UBA provides continuous, automated monitoring and immediate alerts.
Related concept
Static NAT maps one inside address to one outside address.
✗
Increase the sample size to 50% of logs for better coverage.
Why it's wrong here
More manual checks will increase workload and delays.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CRISC NAT questions on configuration and troubleshooting.
