Dependency & Supply Chain Security

Control third‑party risk across ecosystems, from selection and pinning to provenance, scanning, and rapid response.

Policy and Governance

• Maintain allow‑listed registries and scopes; disallow direct installs from untrusted sources.
• Require lockfiles and version pinning; prefer digest pinning for images and vendored assets.
• Generate SBOMs for apps/images; store with artifacts; attest provenance (SLSA, Sigstore).

Package Hygiene (npm focus applicable to others)

• Regularly audit (npm audit, ecosystem SCA) and patch; enforce SLAs by severity.
• Use deterministic builds: npm ci (not npm install) in CI/CD; maintain lockfile consistency.
• Avoid install scripts that execute on install when possible; review for risk.
• Use .npmrc to scope private registries; avoid wildcard registries; enable integrity verification.
• Enable account 2FA for publishing

Development Practices

• Minimize dependency footprint; remove unused packages; prefer stdlib/first‑party for trivial tasks.
• Protect against typosquatting and protestware: pin maintainers, monitor releases, and use provenance checks.
• Hermetic builds: no network in compile/packaging stages unless required; cache with authenticity checks.

CI/CD Integration

• SCA, SAST, IaC scans in gates; fail on criticals; require approvals for overrides with compensating controls.
• Sign artifacts; verify signatures at deploy; enforce policy in admission.

Vulnerability Management

• For patched vulnerabilities: test and deploy updates; document any API breaking changes.
• For unpatched vulnerabilities: implement compensating controls (input validation, wrappers) based on CVE type; prefer direct dependency fixes over transitive workarounds.
• Document risk decisions; escalate acceptance to appropriate authority with business justification.

Incident Response

• Maintain rapid rollback; isolate compromised packages; throttle rollouts; notify stakeholders.
• Monitor threat intel feeds (e.g., npm advisories); auto‑open tickets for critical CVEs.

Implementation Checklist

• Lockfiles present; integrity checks on; private registries configured.
• SBOM + provenance stored; signatures verified pre‑deploy.
• Automated dependency updates with tests and review gates.
• High‑sev vulns remediated within SLA or mitigated and documented.
