Introduction

In today's software development landscape, security can no longer be an afterthought. DevSecOps integrates security practices into every phase of the development lifecycle, ensuring vulnerabilities are caught early and often. In this comprehensive guide, I'll walk you through building a complete DevSecOps CI/CD pipeline from scratch, demonstrating both vulnerable and secure code implementations.

What You'll Learn: • Setting up automated security testing in CI/CD pipelines • Understanding SAST, SCA, and code quality checks • Identifying and fixing common security vulnerabilities • Implementing DevSecOps best practices
