The best course of action is to plan the upgrade during a low-traffic period and implement compensating controls such as additional monitoring during the downtime. This choice directly addresses the core challenge of balancing risk treatment with business downtime by treating the outdated encryption vulnerability while avoiding full acceptance of unacceptable exposure. Compensating controls, like enhanced intrusion detection and real-time monitoring, reduce the likelihood of exploitation during the 48-hour window, aligning with the organization’s low risk appetite for data breaches without incurring catastrophic revenue loss. On the CRISC exam, this scenario tests your ability to apply risk-based decision-making under operational constraints—a common trap is choosing to simply accept the risk or delay the upgrade indefinitely, which violates the low risk appetite. The key is recognizing that compensating controls allow you to treat the root cause while temporarily managing residual risk. Memory tip: “Plan, patch, and protect—schedule the fix, then watch the gaps.”
CRISC IT Risk Assessment Practice Question
This CRISC practice question tests your understanding of it risk assessment. 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.
A multinational corporation is conducting a risk assessment for its new online payment platform. The platform processes transactions in multiple currencies and stores sensitive customer financial data. The risk team has identified that the encryption algorithm used for data at rest is outdated and could be vulnerable to advanced attacks. The company's risk appetite is low for data breaches. The security team recommends upgrading the encryption to a modern standard, but the upgrade will require a 48-hour downtime impacting all global transactions. The business unit is concerned about revenue loss during the downtime. As the risk practitioner, what is the BEST course of action to balance security and business continuity?

Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Plan the upgrade during a low-traffic period and implement compensating controls such as additional monitoring during the downtime.
Option B is the best course of action because it balances the need to mitigate a high-risk encryption vulnerability with business continuity. By scheduling the upgrade during a low-traffic period and implementing compensating controls (e.g., enhanced monitoring and intrusion detection), the organization reduces the likelihood of exploitation during the 48-hour downtime while minimizing revenue loss. This aligns with the low risk appetite for data breaches and demonstrates a risk-based decision that treats the vulnerability without accepting unacceptable exposure.
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.
✗
Accept the risk and delay the upgrade until the next scheduled maintenance window in three months.
Why it's wrong here
Delaying the upgrade increases risk of data breach.
✓
Plan the upgrade during a low-traffic period and implement compensating controls such as additional monitoring during the downtime.
Why this is correct
This reduces risk while minimizing business disruption.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Outsource the payment processing to a third-party vendor that already uses modern encryption.
Why it's wrong here
Outsourcing introduces new risks and may not be timely.
✗
Implement the upgrade immediately to mitigate the vulnerability, accepting the revenue loss.
Why it's wrong here
Unnecessary revenue loss when a less disruptive option exists.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose immediate remediation (Option D) without considering business impact, failing to recognize that risk management requires balancing security with operational continuity through compensating controls and scheduling.
Detailed technical explanation
How to think about this question
The outdated encryption algorithm likely refers to a deprecated standard such as DES or 3DES, which are vulnerable to brute-force attacks due to small key sizes (e.g., 56-bit for DES). Modern standards like AES-256 with XTS mode for data at rest provide strong protection. Compensating controls during downtime could include deploying network segmentation, enabling enhanced logging and SIEM alerting, and implementing application-layer monitoring to detect any anomalous access attempts, effectively reducing the attack surface while the system is offline.

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.
