DevSecOps builds security into the software delivery pipeline rather than bolting it on at the end — 'shift left', so issues are caught early and cheaply.

DevSecOps Pipeline

Building security into software delivery.

1. Plan (threat model)

Security by design.

Consider security requirements and threats before coding. Shifting left starts here — cheaper to design in than to bolt on later.

Security in the pipeline

Shift left — test for security as early as possible, when fixes are cheapest.
SAST / DAST / SCA — static analysis (code), dynamic analysis (running app) and software composition analysis (third-party dependencies) run automatically in CI/CD.
Secrets management — never hard-code credentials; use a vault.
IaC scanning — scan Infrastructure as Code for misconfiguration before deployment.

The culture shift: security is everyone's responsibility, automated into the workflow developers already use. It combines programming and security, and is a fast-growing, well-paid specialism.

Interview Intelligence

How this topic actually shows up in interviews — and how to demonstrate you understand it.

Why employers ask about this

DevSecOps blends coding and security into a highly paid, in-demand modern discipline.

Technical questions

How would you integrate security into a CI/CD pipeline?+

Add SAST, SCA and IaC scanning to the pipeline, manage secrets in a vault, and gate on critical findings.

Behavioural questions

Describe improving a process by building quality in early.+

Show catching issues earlier rather than at the end, and the benefit.

Real-world scenarios

“A team ships fast but keeps introducing vulnerabilities.”+

Expected answer: Shift security left — add automated SAST/SCA to CI/CD and secrets scanning, so issues are caught before release.

Frequently asked questions

What does 'shift left' mean?

Moving security testing earlier in the development lifecycle, where issues are cheaper and easier to fix.

What is the difference between SAST and DAST?

SAST analyses source code statically; DAST tests the running application dynamically for vulnerabilities.

Why manage secrets in DevSecOps?

Hard-coded credentials leak easily; a secrets vault keeps them out of code and rotatable.
