Software Supply Chain Attestations in CI/CD
Software supply chain security is no longer only about scanning dependencies. Teams increasingly need to prove what they built, where it came from, and which process produced the artifact that finally reached production.
What attestations add
- provenance for who or what built the artifact
- stronger release verification than filename trust
- a reviewable chain between source, workflow, and deployable output
A useful rollout order
- generate SBOMs consistently
- attach provenance to build artifacts
- verify signatures or attestations before promotion
- block production deploys that skip the trusted path
What to avoid
- producing attestations nobody verifies
- treating generated metadata as security by itself
- leaving emergency bypasses undocumented
The real win is operational trust. When incidents happen, teams can answer what shipped and how with far less guesswork.
