Integration with CI/CD

Integrate GHAS security checks into CI/CD so vulnerable code cannot be merged or deployed unnoticed.

Simple Explanation (ELI5)

CI/CD integration means every code change must pass security checks automatically before it can move forward.

Technical Explanation

Security in CI/CD requires workflow orchestration: scans on PR, policy checks on main, scheduled deep scans, and deployment gates based on severity thresholds. Branch protection enforces compliance.

Debugging Scenarios

• Gate not blocking merges: Required status checks not mapped correctly.
• Fork PR cannot access secrets: Use safe patterns; avoid exposing secrets to untrusted contexts.
• Pipeline unstable: Split scan jobs and isolate flaky dependencies.
• Security checks bypassed via admin merge: Restrict bypass permissions and audit events.

Real-world Use Case

A CI security gate blocked a high-severity vulnerable dependency in a release PR, preventing deployment of exploitable code to production.

Summary

CI/CD integration is where GHAS becomes enforceable: security findings become merge decisions, not optional reports.
