Your application is only as secure as its weakest dependency. Log4Shell showed that one vulnerable library can compromise millions of systems.

Dependency Scanning¶

npm audit && npm audit fix pip-audit govulncheck ./… trivy fs –scanners vuln . trivy image myapp:latest

CI/CD Integration¶

GitHub Actions¶

• uses: aquasecurity/trivy-action@master with: scan-type: ‘fs’ severity: ‘HIGH,CRITICAL’ exit-code: ‘1’

Best Practices¶

1. Update regularly (Dependabot, Renovate)
2. Always commit lockfiles
3. Scan in CI/CD — block CRITICAL/HIGH
4. Minimize dependencies
5. Verify integrity (npm integrity, pip –require-hashes)

Key Takeaway¶

Automate dependency scanning in CI/CD. Update regularly. Every outdated library is a potential entry point.
