Security Overview & Policy Baseline¶

Security is a foundational pillar of jambazid/gha-actions. Because these composite actions and workflows are consumed across downstream production CI/CD pipelines, protecting the software supply chain against vulnerabilities and injection attacks is vital.

🛡️ Security Pillars¶

Our security model relies on four primary layers of defense:

1. Supply-Chain Integrity: Strict enforcement of 40-character commit SHA pinning for all external GitHub Actions.
2. Static Action Analysis (zizmor): Automated detection of GitHub Actions security anti-patterns (e.g. unpinned actions, template injection, credential leakage).
3. Vulnerability Scanning (Trivy): Continuous scanning of repository code, scripts, and dependency trees.
4. Least Privilege Permissions: Explicit scoping of GITHUB_TOKEN permissions across all composite actions and reusable workflows.
