KCSA Platform Security Practice Question
Your security team has discovered that an application container image contains outdated packages with known remote code execution vulnerabilities. Which phase of the software development lifecycle is the most effective place to initially scan and remediate these vulnerabilities?
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
✓
CI/CD pipeline build stage
Scanning images during the CI/CD pipeline build phase allows developers to patch or replace vulnerable packages before the image is ever pushed to a registry or deployed to production.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Node OS package manager updates
Why it's wrong here
Node updates affect the host operating system, not the container image application dependencies.
- ✗
Kubelet container startup phase
Why it's wrong here
While admission controls can block startup, identifying issues only at startup delays feedback to developers.
- ✓
CI/CD pipeline build stage
Why this is correct
Scanning during the CI/CD build phase catches vulnerabilities early and prevents vulnerable images from entering registries.
- ✗
Kubernetes API server audit logging
Why it's wrong here
Audit logs record API requests after the fact and do not scan or remediate image contents.
