Software Supply Chain Security: SLSA, Sigstore and Dependencies

Learn how software supply chain security stops attacks like SolarWinds and XZ Utils and how to protect your builds and dependencies.

Summary: An SBOM (Software Bill of Materials) is a machine-readable inventory of all software components, libraries, and dependencies in an application - including open-source packages, versions, and licenses. SBOMs enable the rapid identification of affected systems in the event of new CVEs (e.g., Log4Shell) and are required by regulation under U.S. Executive Order 14028 and the EU Cyber Resilience Act.
