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

A modern DevSecOps pipeline usually looks like this:

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.

For example:
• 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.
