Supply-chain Levels for Software Artifacts Specification, Version 1.0¶
OpenSSF. (2023). Supply-chain Levels for Software Artifacts Specification, Version 1.0.
Cited by¶
2 citations across 2 artifacts.
Each citation links to the sentence it supports in the citing article.
Mechanisms¶
- Base Image Provenance Attestation
- A perfectly attested image can be packed with known-vulnerable packages; the attestation proves where it came from, not that what came is good.
This sourceDefines provenance attestations as claims about where and how an artifact was produced, not as a guarantee of the artifact’s intrinsic quality or vulnerability status.
- A perfectly attested image can be packed with known-vulnerable packages; the attestation proves where it came from, not that what came is good.
- Signed Manifest or Checksum
- The discipline is to pair the manifest with build provenance — attestations of how and from what the artifact was built, as formalized by frameworks like SLSA — so the signed content traces back to a trustworthy build, not merely to a consistent download.
This sourceFormalizes build-provenance attestations recording how and from which inputs an artifact was produced so integrity traces back to the build.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
