SBOM: Software Bill of Materials in Cybersecurity
Software Bill of Materials; 'S' letter plus 'bom'.
SBOM stands for Software Bill of Materials. A Software Bill of Materials is a formal inventory of all components, libraries, and dependencies in a software product. SBOMs use standardized formats like SPDX or CycloneDX to document component names, versions, and supplier relationships.
Why this matters in 2026
SolarWinds shipped malicious signed updates to ~18,000 customers in 2020 because no SBOM existed at the build-environment level. Executive Order 14028 cited this directly. SBOM consumption (machine-readable, programmatically validated) is now mandatory in NIST CSF, FedRAMP, and CMMC under negotiation.

Security engineers generate SBOMs during the build process and monitor them for newly disclosed vulnerabilities in third-party components. GRC analysts audit SBOM completeness to meet supply chain security requirements under frameworks like NIST SSDF and Executive Order 14028. Security architects define SBOM policies that govern which components are approved for use.
