DevSecOps
An approach that integrates security practices into every phase of the DevOps pipeline, making security a shared responsibility across development, security, and operations teams.
Definition
DevSecOps extends DevOps by embedding security at every stage: secure coding training for developers, SAST/DAST scanning in CI/CD, infrastructure security scanning, runtime protection, and continuous monitoring. The goal is "shift left" — finding security issues earlier when they're cheaper to fix. Tools like diffray, Snyk, and Checkmarx integrate security into the development workflow.
Pourquoi c'est important
Traditional security reviews at the end of development are too late and too slow. DevSecOps catches 50% of vulnerabilities before code reaches production, reducing the cost of fixes by 10-100x. Companies with mature DevSecOps programs have 50% fewer security incidents.
Exemple
A DevSecOps pipeline includes: pre-commit hooks running secrets detection, PR checks with diffray security scanning, container image scanning before deployment, and runtime application protection in production.
