CCSP Practice Question: A cloud security architect is implementing a…
A cloud security architect is implementing a CI/CD pipeline for a containerized application on AWS. Which TWO practices should be integrated to enforce container image security?
⚠ Common exam trap
ISC2 often tests the distinction between pipeline-time security controls (like scanning and signing) and runtime or perimeter controls (like RASP and WAF), leading candidates to mistakenly select runtime defenses for a CI/CD enforcement question.

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
✓
Scan container images for vulnerabilities before push to registry
Scanning container images for vulnerabilities before pushing them to a registry is a critical shift-left security practice. It ensures that known Common Vulnerabilities and Exposures (CVEs) in base images or application dependencies are detected and remediated early in the CI/CD pipeline, preventing insecure images from being deployed. Tools like Trivy, Clair, or AWS ECR image scanning integrate directly into the pipeline to enforce this policy.
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 runtime application self-protection (RASP)
Why it's wrong here
RASP is a runtime control, not a CI/CD integration.
- ✓
Scan container images for vulnerabilities before push to registry
Why this is correct
Correct. Pre-registry scanning catches vulnerabilities early.
- ✗
Use a cloud WAF to protect the containerized application
Why it's wrong here
WAF is a runtime protection, not a CI/CD security measure.
- ✓
Sign container images to ensure integrity
Why this is correct
Correct. Signing prevents tampering and ensures authenticity.
- ✗
Run SAST on the application source code
Why it's wrong here
SAST is for source code, not container images.
