How do Software Supply Chain vulnerabilities occur and how do tools like npm audit help?
❓ Interview Prompt: Explain Software Supply Chain security, transitive dependencies, known CVE vulnerabilities, lockfiles, and `npm audit` / Snyk.
Modern web applications rely on hundreds of open-source third-party libraries ('node_modules'). Software Supply Chain attacks exploit vulnerabilities hidden in these dependencies:
Defensive Workflow:
1
Lockfile Enforcement: Commit 'package-lock.json' to guarantee reproducible builds.
2
Automated Vulnerability Scanning: Run 'npm audit' or Snyk in CI/CD pipelines to scan dependencies against known CVE databases.
3
Dependabot Updates: Automatically apply security patch updates for vulnerable dependencies.
Code Implementation Example
bash
# Execute automated dependency security audit in CI/CD:
npm audit --audit-level=high💡Running automated dependency vulnerability scans with npm audit.
🎯 Interview Key Takeaway
Audit third-party dependencies regularly in CI/CD pipelines using npm audit or Snyk to fix known CVE vulnerabilities.
