A secure DevOps toolchain is a sequence of integrated tools used to automate the entire lifecycle of application delivery — from design, build and test, to deploy and monitor — while embedding security at each stage. Key tools include code repositories, build servers, configuration management, test automation, and monitoring services. Security is integrated through static and dynamic code analysis tools, container security, secrets management, and automated compliance checks, nurturing a culture of shift-left security., CI/CD security is the distribution of security practices and measures throughout the continuous integration and continuous delivery (CI/CD) pipeline. As a core component of DevSecOps, CI/CD security dismisses the idea that security is a distinct phase and instead ensures it is an inherent part of the software delivery lifecycle. The goal of CI/CD security is to detect and mitigate , CI/CD Security Cheat Sheet Introduction CI/CD pipelines and processes facilitate efficient, repeatable software builds and deployments; as such, they occupy an important role in the modern SDLC. However, given their importance and popularity, CI/CD pipelines are also an appealing target for malicious hackers, and their security cannot be ignored. This goal of this cheat sheet is to provide .
