What is DevSecOps?
DevOps accelerated the delivery of software, but often at the expense of security. In the rush to deploy new features, configurations were missed and insecure code was pushed to production. DevSecOps aims to fix this by integrating security practices into every stage of the DevOps lifecycle—from planning to monitoring.
The DevSecOps Loop
Security is no longer a separate phase; it is embedded in the continuous delivery cycle:
- Plan: Threat modeling and security requirements definition.
- Build: Static analysis (SAST) and software composition analysis (SCA) running in developer workspaces.
- Test: Dynamic application security testing (DAST) on built containers.
- Deploy: Automated configuration checks and compliance validation.
