Harness enhances CI/CD pipeline security by integrating automated security testing, secret management, and compliance checks with frameworks like OWASP and SLSA, achieving SLSA L3 v1.0 compliance for secure software delivery. CI/CD practices are crucial in modern software development, allowing for automation and streamlining of the release process, where CI focuses on integrating code changes into a shared repository for early issue detection, and CD automates deployment to production environments. Common security challenges in CI/CD include manual processes, delayed feedback, siloed visibility, inconsistent governance, and complex security management, which Harness addresses through tools like Wiz, Snyk, and Semgrep, as well as AI-driven recommendations. By incorporating security throughout the development lifecycle, CI/CD supports DevSecOps by automating security tests, shifting security left, providing continuous monitoring, and ensuring compliance, thus fostering a collaborative environment where security is a shared responsibility. Harness further supports secure cloud-hosted builds through features like Secure Connect, role-based access control, audit trails, and policy-as-code mechanisms, positioning itself as the only vendor supporting the SLSA L3 v1.0 standard at the time of the writing.
