ISC Infrastructure And System Security Practice Question
An organization is migrating to a serverless architecture. Which security control is most effective at preventing 'Insecure Serverless Function Configuration' attacks?
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 CI/CD pipeline security and IaC scanning.
Using Infrastructure as Code (IaC) scanning tools to audit function configurations before deployment ensures that least privilege and networking are correctly applied.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Monitor CloudWatch logs for abnormal function execution.
Why it's wrong here
Monitoring is reactive; prevention via IaC is superior.
- ✗
Enable runtime application self-protection (RASP).
Why it's wrong here
RASP is for code-level attacks, not infrastructure misconfiguration.
- ✓
Implement CI/CD pipeline security and IaC scanning.
Why this is correct
Preventative scanning of IaC is the best way to catch configuration drift before deployment.
- ✗
Regularly rotate the function's execution role.
Why it's wrong here
Rotation doesn't help if the underlying permissions are too broad.
