CRISC Risk Response and Mitigation Practice Question
Exhibit
Refer to the exhibit. SIEM alert log: Time: 2025-03-20 14:23:45 Source IP: 10.0.1.50 Destination: server1.company.local (192.168.1.10) Event: Multiple failed logins (15 attempts in 30 seconds) Current state: No account lockout policy enabled.
Based on the exhibit, which risk response should be prioritized?
⚠ Common exam trap
A common mix-up: candidates choose 'Accept the risk because it's only a single server' (Option C), mistakenly believing that a single server has low impact, but failing to recognize that a compromised server can serve as a pivot point for broader network attacks or data exfiltration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement account lockout policy
The exhibit indicates a single server with a known vulnerability that could lead to unauthorized access. Implementing an account lockout policy directly mitigates the risk of brute-force attacks by limiting the number of failed login attempts, which is a cost-effective and immediate control. This aligns with the risk response strategy of mitigation, reducing the likelihood of exploitation without the operational impact of taking the server offline.
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 account lockout policy
Why this is correct
Account lockout reduces the effectiveness of brute-force attacks.
- ✗
Avoid by taking the server offline
Why it's wrong here
Taking the server offline is extreme and not required.
- ✗
Accept the risk because it's only a single server
Why it's wrong here
Acceptance is not appropriate given the active threat.
- ✗
Transfer the risk to a cloud provider
Why it's wrong here
Transfer is not relevant here.
