Zero Trust in CI/CD Pipelines: A Practical DevSecOps Implementation Guide

Securing modern CI/CD pipelines has become significantly more challenging as teams adopt cloud-native architectures and accelerate their release cycles. Attackers now target build systems, deployment workflows, and the open-source components organizations rely on every day. This tutorial provides a practical look at how Zero Trust principles can strengthen the entire software delivery process. It walks through real steps you can apply immediately using identity-based authentication, automated scanning, policy checks, and hardened Kubernetes deployments. The goal is simple: make sure that only trusted code, moving through a trusted pipeline, reaches production. As organizations continue transitioning to cloud-native applications and distributed systems, the CI/CD pipeline has become a critical part of the software supply chain. Unfortunately, this also makes it an increasingly attractive target for attackers. Compromising a build system or deployment workflow can lead to unauthorized code changes, credential theft, or even the silent insertion of malicious workloads into production.
