SBOM and Provenance

Overview

SBOMs describe what is in your software. Provenance describes how it was built. Together they enable better risk management and incident response.

When to Use

  • Meeting compliance or customer requirements for transparency
  • Improving vulnerability impact analysis
  • Implementing SLSA-style supply-chain levels

Practices

  • Generate SBOMs as part of the build (CycloneDX or SPDX)
  • Attach or store provenance (who built it, from what source, with what tools)
  • Make SBOM + provenance available to downstream consumers and security tools
  • Keep generation deterministic and integrated into CI
  • Use SBOMs for continuous vulnerability monitoring

Principles

  • An SBOM that is not updated or consumed has limited value
  • Prefer automated generation over manual lists
  • Treat provenance as a security control, not just documentation

Verification

  • SBOMs are produced for released artifacts
  • Provenance is verifiable and linked to the artifact
  • Security tooling can consume the SBOMs effectively
