Protecting software components from compromise
Supply Chain Security is a set of measures to protect all software components from compromise at any stage of development and delivery.
Threats
- Malicious code in dependencies
- Compromised npm/PyPI packages
- CI/CD pipeline attacks
- Build artifact substitution
- Vulnerabilities in open-source libraries
Protection Measures
- Dependency auditing (npm audit, Snyk)
- Package signing and verification
- SBOM (Software Bill of Materials)
- Lockfiles and version pinning
- Private package repositories
Tools
- Dependabot / Renovate
- Snyk, Sonatype Nexus
- Sigstore / Cosign
- SLSA Framework
- GitHub Advanced Security
Best Practices
- Minimize dependencies
- Regular library updates
- CVE and vulnerability monitoring
- Package reputation verification
- Build environment isolation
