Introduction Understanding how CI/CD pipelines are attacked is only half the picture. Threat modeling and attack taxonomy give us a map of the battlefield, but without concrete defensive patterns and engineering mitigations, that knowledge remains theoretical. This guide bridges the gap between awareness and action. The goal is not to build an impenetrable fortress — … Read more
Introduction Software supply chain attacks have surged in both frequency and sophistication over the past several years. Rather than attacking applications directly, adversaries increasingly target the dependency resolution and artifact distribution layers that underpin modern software development. Two of the most effective techniques in this category are dependency confusion and artifact poisoning. These attacks exploit … Read more
Introduction: Why Manual Security Reviews Don’t Scale Every engineering team eventually hits the same wall: security reviews that depend on human eyeballs cannot keep pace with the velocity of modern CI/CD pipelines. When teams deploy dozens or hundreds of times per day, asking a security engineer to manually review every Terraform plan, Kubernetes manifest, or … Read more
Introduction: Why Secrets Are the #1 Cause of CI/CD Compromise If you examine the root cause of almost every major CI/CD breach in recent years — from the Codecov supply chain attack to the CircleCI security incident — you will find the same culprit: compromised secrets. API keys, cloud credentials, database passwords, signing certificates — … Read more
Overview Third-party GitHub Actions are one of the most convenient features of the GitHub ecosystem. With a single uses: directive, you can pull in complex build logic, deploy to cloud providers, or run security scanners. But that convenience comes with a critical trade-off: every third-party action executes code in your CI environment with access to … Read more
Introduction: Why Artifact Signing Matters in CI/CD Modern software delivery pipelines are remarkably good at building and shipping code fast. But speed without trust is a liability. Between the moment source code is committed and the moment a container image runs in production, there is a gap — a gap where tampering, substitution, or silent … Read more
Introduction If you can’t reproduce a build, you can’t verify it. This simple truth sits at the heart of software supply chain security. Build integrity ensures that what you deploy is exactly what you intended to build — nothing added, nothing modified, nothing tampered with between source code and production artifact. In recent years, supply … Read more
Your CI/CD pipeline can have airtight security controls—signed commits, pinned dependencies, SAST scans, container image signing—but none of it matters if the deployment process itself is weak. Deployment is the critical junction where pipeline security meets production security. A compromised deployment workflow can bypass every upstream control you have built, pushing malicious code straight into … Read more
Introduction CI/CD pipelines are among the most privileged components in any modern software organization. They clone source code, access secrets, build artifacts, and deploy to production — often with minimal human oversight. Yet despite this extraordinary level of access, the trust models underpinning these pipelines are rarely made explicit. When a pipeline runs, it implicitly … Read more
“Shift left” has become one of the most widely adopted principles in DevSecOps. The idea is simple and appealing: move security earlier in the software development lifecycle to detect issues sooner, reduce costs, and improve overall security outcomes. Over time, “shift left” has evolved from a useful concept into a near-unquestioned dogma. Security scanning, testing, … Read more
