How would you answer an interview scenario involving image signing and provenance in Container Security?

For an interview scenario involving image signing and provenance, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Signing and provenance prove where a container image came from and how it was built. For production, sign images in trusted CI, record provenance, restrict deployable registries, and verify signatures with admission policy. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
