Your organization uses a 'Golden Image' approach for build containers. To prevent supply chain contamination of these build environments, what is the most effective security control?
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 image signing and verification (e.g., Docker Content Trust or Cosign).
Using signed, immutable images from a private container registry ensures that build environments cannot be altered by unauthorized parties.
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 image signing and verification (e.g., Docker Content Trust or Cosign).
Why this is correct
Signing and verifying images guarantees that the container running the build is exactly what was approved.
- ✗
Disable all outbound network access from the build server.
Why it's wrong here
This would break package installation from internal repositories.
- ✗
Automatically pull the latest 'alpine' image during build time.
Why it's wrong here
Pulling 'latest' is dangerous as it allows silent updates to malicious versions.
- ✗
Rotate the build server SSH keys daily.
Why it's wrong here
Key rotation is good for management but does not prevent image contamination.
