An SBOM is a machine-readable inventory of the components in a software artifact; SPDX and CycloneDX are the two widely used formats, and generating one per release supports vulnerability matching and licence review.

What it is

A software bill of materials lists the packages, versions, suppliers, licences and relationships that make up a delivered artifact. SPDX is an ISO-standardised format with a strong licence-metadata heritage; CycloneDX, an OWASP project, focuses on security use cases and also covers services and vulnerabilities. Both are supported by generators for common ecosystems and container images.

Why it matters

When a vulnerability such as a widely used logging library flaw is announced, an organisation with SBOMs can search them instead of rebuilding every project. Licence obligations (attribution, copyleft) can be checked from the same data.

How to apply

Generate the SBOM in the release pipeline from the lockfile and the built artifact, and store it next to the artifact.
Choose one format for internal use and be able to export the other on request.
Feed SBOMs to a vulnerability matcher and a licence policy check.
Include the SBOM of base images for container deliveries.

Pitfalls

An SBOM generated from source manifests may differ from what is actually in the image; generate from the artifact where possible. SBOMs age; regenerate per release, not per year.
