CSSLP Practice Question: Secure Software Deployment Operations And Management
You are troubleshooting a production incident where a legacy application is performing insecure cryptographic operations. Which feature of a Web Application Firewall (WAF) can best help mitigate the risk while a code fix is being developed?
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
✓
Deploy a custom WAF rule to block requests containing anomalous cryptographic parameters.
WAFs allow for virtual patching by blocking specific attack patterns before they reach the vulnerable code, buying time for developers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Upgrade the SSL/TLS certificate to a higher bit-length.
Why it's wrong here
Upgrading the certificate does not fix insecure cryptographic usage within the application code.
- ✓
Deploy a custom WAF rule to block requests containing anomalous cryptographic parameters.
Why this is correct
Custom rules allow for rapid mitigation of specific exploit vectors targeting application logic.
- ✗
Enable HTTP/2 protocol enforcement on the WAF load balancer.
Why it's wrong here
Protocol enforcement does not address application-level cryptographic vulnerabilities.
- ✗
Disable the WAF's logging feature to improve response time during the incident.
Why it's wrong here
Disabling logging hinders forensic analysis and incident response.
