SBOM is the abbreviation for Software Bill-of-Materials, or the “ingredient list” for all the software in your solution (application, device, etc.). It includes operating systems, applications, libraries, browsers, buffers, compression engines, containers, and other pieces of code.
SBOM Central supports the OWASP CycloneDX standard (external link). It is a lightweight SBOM standard designed for use in application security contexts and supply chain component analysis.
