Supply Chain Security Principles
Guidelines for securing the software supply chain.
When to Invoke
- Auditing project dependencies
- Setting up CVE scanning in CI/CD
- License compliance review
- Responding to supply chain vulnerability disclosures
Dependency Security
CVE Scanning
| Language | Tool | Command |
|---|
| Go | govulncheck | govulncheck ./... |
| Rust | cargo audit | cargo audit |
| Python | pip-audit | pip-audit |
| Node.js | npm audit | npm audit |
| Java | OWASP Dependency-Check | mvn dependency-check:check |
| .NET | Built-in | dotnet list package --vulnerable |
| Ruby | bundle audit | bundle audit check --update |
| PHP | composer audit | composer audit |
Scanning Frequency
- Every CI run — fail build on critical/high CVEs
- Weekly scheduled scan — catch newly disclosed vulnerabilities
- On dependency update — verify new version is clean
SBOM (Software Bill of Materials)
Generation
cyclonedx-gomod mod -json -output sbom.json
npx @cyclonedx/cyclonedx-npm --output-file sbom.json
cyclonedx-py poetry --format json -o sbom.json
Usage
- Attach SBOM to releases
- Track all transitive dependencies
- Enable downstream vulnerability analysis
License Compliance
Risk Levels
| License | Risk | Action |
|---|
| MIT, BSD, Apache 2.0 | Low | Permissive — generally safe |
| LGPL | Medium | Review linking requirements |
| GPL | High | Copyleft — may require source disclosure |
| AGPL | Critical | Network copyleft — consult legal |
| No license | Critical | Cannot use — no rights granted |
Automation
- Use
license-checker (Node.js), pip-licenses (Python), cargo-license (Rust)
- Maintain allowlist/denylist of approved licenses
- Fail CI on disallowed licenses
Supply Chain Attack Prevention
- Lock files committed —
package-lock.json, go.sum, Cargo.lock, poetry.lock
- Pin exact versions in production — no floating ranges
- Verify checksums — lock files contain integrity hashes
- Review new dependencies — check maintainer, downloads, last commit, open issues
- Minimal dependencies — each dep = increased attack surface
- Signed commits and releases — verify artifact provenance
