DevSecOps and Securing CI/CD Pipelines

DevSecOps represents a cultural and technical shift that integrates security practices directly into the DevOps lifecycle, making security a shared responsibility for development, security, and operations teams. This philosophy is practically implemented by securing the Continuous Integration/Continuous Deployment (CI/CD) pipeline, which automates the process of building, testing, and deploying software. By embedding automated security tools and processes—such as static code analysis (SAST), software composition analysis (SCA) for dependencies, and container scanning—at every stage of the pipeline, organizations can identify and remediate vulnerabilities early and continuously, rather than treating security as a final, separate gate. This "shift-left" approach ensures that security is built into the application from the outset, enabling faster, more secure software delivery.
