DevSecOps and Shift Left — Security from the First Line of Code

Security tested only before production deployment is too late. Shift Left means moving security controls as early as possible — ideally into the developer workflow.

Security in CI/CD Pipeline¶

Every merge request automatically goes through:

• SAST (Static Application Security Testing) — SonarQube scans code for vulnerabilities
• Dependency scanning — OWASP Dependency-Check controls known CVEs in libraries
• Secret detection — GitLeaks searches for accidentally committed API keys and passwords
• Container scanning — Trivy scans Docker images

Security Champions¶

In every development team, one “security champion” — a developer with interest in security who has undergone extra training. They’re not a security expert, but can identify basic issues in code review and escalate.

Metrics¶

We track: mean time to repair critical vulnerability (MTTR), number of vulnerabilities found in CI vs. production, false positive rate. Goal: 90% of vulnerabilities found before production deployment.

Security is Team Responsibility¶

DevSecOps isn’t about tools — it’s about culture. When a developer thinks about security from the first line, the result is more secure software.
