DevSecOps Handbook
Welcome to the DevSecOps Handbook β the definitive guide for integrating security seamlessly into your Software Development Life Cycle (SDLC) and CI/CD pipelines. This guide is built to help engineering and security teams automate compliance, enforce policy as code, and measure security maturity.
π Overviewβ
Historically, security was an afterthoughtβa bottleneck introduced at the end of the software delivery process. DevSecOps shifts this paradigm by building security directly into agile development and operations, ensuring that the software is secure by design.
π― Learning Objectivesβ
By the end of this module, you will be able to:
- Understand the Shift-Left Philosophy and build a scalable Security Champions program.
- Automate security testing within CI/CD pipelines using SAST, DAST, SCA, and Secret Scanning.
- Implement Policy as Code (PaC) to automatically govern infrastructure and Kubernetes configurations using OPA and Kyverno.
- Triage vulnerabilities using risk-based prioritization (CVSS v4.0) and enforce SLA tracking.
- Measure your organization's DevSecOps maturity using frameworks like OWASP SAMM.
π οΈ Prerequisitesβ
- Basic understanding of CI/CD concepts (GitHub Actions, GitLab CI, or Jenkins).
- Familiarity with containerization (Docker) and orchestration (Kubernetes).
- Basic scripting and YAML syntax.
