What is DevSecOps?
⚡
Quick Answer
DevSecOps integrates security into every stage of the DevOps lifecycle — shifting it left so that security is automated and continuous rather than a gate at the end.
Detailed Answer
It embeds automated checks (SAST, DAST, dependency and image scanning, IaC and secrets scanning) into CI/CD, plus policy-as-code at deploy time and runtime monitoring. The cultural shift is shared security ownership across dev, ops, and security, so vulnerabilities are caught early when they are cheap to fix.

Interview Tip
Emphasize shift-left + automation in the pipeline and shared ownership — DevSecOps is a culture change, not a tool.
