DevSecOps Basics: Security in Every Pipeline
Learn what DevSecOps means for a DevOps engineer: shift left, the main security scans, who owns what, and a first secure pipeline you build yourself.
What You'll Learn
Understanding the DevSecOps Mindset
This module is a map. It shows what security checks exist, where they sit in a pipeline, and which module teaches each one in depth.
Mapping the Security Checks in a Pipeline
A secure pipeline is not one tool. It is a handful of small checks at the right stages, each catching a different kind of problem.
Keeping Secrets Out of Code
Leaked credentials are the most common and most avoidable security incident, so this is the first habit to build.
Finding Flaws in Code and Dependencies
Your application is two things: the code your team wrote, and the libraries you pulled in. They need different checks.
Checking Images and Infrastructure Before They Ship
Container images and Terraform files are both code, and both can ship a weakness into production if nobody scans them first.
Setting a Policy for Findings
Tools only help if the team agrees what to do with their output. A scan that reports but never blocks becomes background noise.

Practice on the Coding Sheet
Not a software engineer sheet. Every problem comes from real DevOps, SRE, Platform and Cloud interviews, from your first script to a system you build yourself.

It means running security checks earlier in the delivery process, such as on a developer's laptop or in a pull request, instead of after release. Problems found earlier are quicker and cheaper to fix.
SAST scans the code your team wrote for risky patterns. SCA scans the third-party libraries you use for known vulnerabilities. A clean codebase can still be exposed through one outdated dependency, so you need both.
No. A DevOps engineer builds the pipeline that runs the checks and decides what blocks a release. The security team defines the policy and handles the hard cases.
For Critical and High findings, yes. A scan that only produces a report gets ignored. Lower severities can go into a tracked backlog with an owner and a deadline.
