Securing the Software Supply Chain

Interview Question

What measures would you take to secure the software supply chain from dependency attacks or compromised packages?

Key Points to Cover
  • Pin versions and use checksum verification
  • Adopt SBOMs and signed artifacts (e.g., Sigstore, Cosign)
  • Scan dependencies regularly for vulnerabilities
  • Apply zero-trust principles and least privilege in CI/CD
Evaluation Rubric
Mentions version pinning and checksums30% weight
Uses signed artifacts and SBOMs30% weight
Automates dependency scanning20% weight
Applies zero-trust practices20% weight
Hints
  • 💡Think SolarWinds, Log4Shell lessons learned.
Common Pitfalls to Avoid
  • ⚠️Not pinning dependency versions, leading to unpredictable behavior and potential introduction of vulnerable versions.
  • ⚠️Neglecting to verify package integrity beyond just downloading from a repository.
  • ⚠️Treating SBOM generation as a one-off task rather than an ongoing process.
  • ⚠️Relying solely on automated vulnerability scans without human oversight or vetting of new dependencies.
  • ⚠️Failing to integrate security checks into the CI/CD pipeline, making them an afterthought.
Potential Follow-up Questions
  • How do you manage private package registries?
  • What about transitive dependency risks?
