Software Composition Analysis Tools

About Software Composition Analysis Tools

Software supply chain security tools protect the integrity of software from development through deployment. The category covers SBOM (software bill of materials) generators that produce machine-readable lists of all components in a software project, artifact signing tools that cryptographically verify build provenance, dependency scanners that check packages against vulnerability databases, and provenance verification tools that confirm artifacts were built by trusted build systems. SBOM tools like Syft and OSV-Scanner enumerate dependencies in container images and project files, producing SPDX or CycloneDX format reports. Signing tools like Cosign and in-toto attach cryptographic signatures to container images and build artifacts, so consumers can verify that images were not tampered with after build time. Dependency scanners like Trivy, Grype, and OWASP Dependency-Check query the NVD, OSV, and other vulnerability databases to find known CVEs in project dependencies. The category has grown in importance following high-profile supply chain attacks like SolarWinds and the npm ecosystem compromises, which demonstrated that attackers can compromise software by injecting malicious code into build pipelines or dependencies rather than attacking the final product directly. Frameworks like SLSA (Supply-chain Levels for Software Artifacts) provide tiered requirements for build integrity, and tools in this category help organizations meet those requirements.
