The most critical control to address first to reduce the risk of unauthorized access is segregation of duties conflict resolution timeliness. This control is foundational because unresolved segregation of duties conflicts allow a single user to retain incompatible roles—such as both creating and approving purchase orders—across multiple systems, enabling unauthorized actions and fraud without detection. On the CRISC exam, this scenario tests your understanding that technical access controls are ineffective if role conflicts persist, as excessive privileges bypass other safeguards. A common trap is choosing a preventive control like encryption or logging, but the question emphasizes timeliness in resolving conflicts as the priority. Remember the mnemonic “SoD First, Then Lock the Door”—resolve role conflicts before layering other controls.
CRISC Risk and Control Monitoring and Reporting Practice Question
This CRISC practice question tests your understanding of risk and control monitoring and reporting. 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.
Exhibit
Refer to the exhibit.
Control Self-Assessment (CSA) Results for Access Management:
- User access recertification completed within 90 days: 92% (target: 95%)
- Terminated employee accounts disabled within 24 hours: 98% (target: 99%)
- Privileged access reviews completed quarterly: 100% (target: 100%)
- Segregation of duties conflicts resolved within 30 days: 85% (target: 90%)
Based on the exhibit, which control is most critical to address first to reduce the risk of unauthorized access?

Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

Correct answer & explanation
✓
Segregation of duties conflict resolution timeliness.
Option A is correct because segregation of duties (SoD) conflict resolution timeliness directly addresses the risk that unresolved conflicts could allow a single user to execute unauthorized actions across multiple systems. If SoD conflicts are not resolved promptly, a user might retain incompatible roles (e.g., both creating and approving purchase orders), enabling fraud or unauthorized access without detection. This control is foundational because it prevents the accumulation of excessive privileges that bypass other access controls.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Segregation of duties conflict resolution timeliness.
Why this is correct
At 85% vs target 90%, unresolved SoD conflicts pose a significant risk of unauthorized transactions.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
Privileged access review frequency.
Why it's wrong here
This control is fully effective.
✗
User access recertification completion rate.
Why it's wrong here
The gap is only 3%, less critical than SoD.
✗
Terminated employee account disabling timeliness.
Why it's wrong here
At 98%, this is close to the target and not the most critical.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISACA often tests the misconception that reactive controls like access reviews or account disabling are more critical than proactive controls like SoD conflict resolution, but the question specifically targets the root cause of unauthorized access—accumulation of incompatible privileges—which only timeliness of SoD resolution can prevent in real time.
Detailed technical explanation
How to think about this question
Segregation of duties relies on role-based access control (RBAC) with conflict matrices that define incompatible combinations (e.g., a user cannot be both a system administrator and an auditor). Timeliness of conflict resolution is measured by mean time to resolve (MTTR) conflicts, often enforced by automated workflows that revoke or adjust roles within minutes of detection. In real-world scenarios, a delay of even a few hours in resolving a SoD conflict can allow a user to approve their own financial transactions, leading to undetected fraud that bypasses audit trails.

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.
