provenance

The provenance analyzer checks for SLSA (Supply-chain Levels for Software Artifacts) provenance and build attestations.

Overview​

Functionality​

This analyzer searches for evidence of secure software supply chain practices:

  1. OCI Labels: Looks for standard OCI labels such as org.opencontainers.image.source and org.opencontainers.image.revision.
  2. BuildKit Metadata: Detects build-time information embedded by Docker BuildKit.
  3. Cosign Signatures: Attempts to find cosign signatures in the registry associated with the image digest.
  4. Attestation Detection: Identifies in-toto or dsse envelopes that might contain build attestations.
