How Security Fits into a CI/CD Pipeline (Beginner-Friendly Breakdown)

Source: Dev.to

Typical DevSecOps Pipeline

• Code Commit
• Build & Test
• Static Code Analysis (SAST)
• Dependency Scanning (SCA)
• Container Image Scanning
• Deployment

Security runs automatically at multiple stages — not just before production.

Security Tools at Each Stage

• Semgrep scans source code
• Snyk checks vulnerable dependencies
• Trivy scans Docker images before pushing

This automation ensures fast feedback and safer releases.

For DevSecOps interns, understanding why security runs at each stage is just as important as knowing how to configure it.
