Enriching SBOMs with Additional Context

Basic SBOMs provide component inventory, but enriched SBOMs deliver actionable intelligence. Vulnerability enrichment adds real-time CVE data, enabling continuous risk assessment. License analysis provides compliance status beyond simple license identification. Component health metrics—maintenance activity, community size, update frequency—help assess operational risks. Quality metrics like test coverage and static analysis results provide holistic component assessment.

Build dependency graphs showing component relationships and transitive dependencies. Visual representations help stakeholders understand complex dependency chains and identify critical components. Include build environment metadata—compiler versions, build tools, configuration flags—that might affect security. Document component provenance when available, tracking source repositories and build attestations. This enrichment transforms SBOMs from simple lists into comprehensive supply chain documentation.
