The answer is implementing stricter access controls and enhanced monitoring. These are correct examples of compensating controls because they provide alternative security measures that reduce risk when a primary control, such as a failed encryption mechanism or a missing physical lock, cannot be deployed or has a deficiency. Compensating controls do not fix the original control; instead, they introduce a different layer of defense—like stricter access restrictions or continuous log review—to achieve an equivalent level of protection. On the CompTIA SecurityX CAS-004 exam, this concept tests your ability to distinguish compensating controls from corrective or detective controls, often appearing in scenario-based questions where a primary safeguard is impractical or cost-prohibitive. A common trap is confusing compensating controls with workarounds that ignore the deficiency; remember, a compensating control must be formally documented and approved. Memory tip: think of a “compensating” employee who covers a missing coworker’s shift—they don’t fix the absence, but they keep the operation running safely.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO of the following are examples of compensating controls for a security control deficiency?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increasing logging and monitoring.
Compensating controls are alternative measures that mitigate the risk from a primary control failure; stricter access and enhanced monitoring are good examples.
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.
✓
Increasing logging and monitoring.
Why this is correct
Enhanced monitoring can detect unauthorized activities that a deficient control might not prevent.
Related concept
Static NAT maps one inside address to one outside address.
✓
Implementing stricter access controls.
Why this is correct
Stricter access controls can compensate for weaknesses in other areas.
Related concept
Static NAT maps one inside address to one outside address.
✗
Accepting the risk.
Why it's wrong here
Risk acceptance is a risk treatment option, not a control.
✗
Purchasing cyber insurance.
Why it's wrong here
Insurance transfers risk, but does not provide a security control.
✗
Re-architecting the network.
Why it's wrong here
Re-architecting is a corrective control, but not necessarily compensating for a specific deficiency.
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 CAS-004 NAT questions on configuration and troubleshooting.
