Episode 40 — Secure the Build Pipeline and Protect Artifacts

Build and release pipelines have become prime targets for attackers, and the CSSLP exam increasingly reflects the need to treat them as critical security assets. This episode outlines the components of a typical pipeline, from source repositories and build runners to artifact registries and deployment mechanisms, and explains how each stage can be hardened. You will hear why locking down runners, restricting network reach, controlling credentials, and preventing unreviewed scripts from executing are essential to maintaining trust. Concepts such as reproducible builds, dependency pinning, code signing, commit verification, and protected branches are presented as concrete defenses that help ensure what ends up in production is exactly what was intended.


Protecting pipeline outputs means treating artifacts, metadata, and provenance information as part of the overall security posture. Examples walk through generating and validating software bills of materials, signing artifacts, and verifying signatures and policies at deployment time so that untrusted or tampered components are rejected automatically. Scenarios emphasize how to structure approvals for sensitive steps, enforce separation of duties around releasing code, and isolate build, test, and production environments so a compromise in one does not easily spread to others. You will also hear how pipeline telemetry can reveal anomalies such as unexpected build triggers, unsigned artifacts, or deviation from normal workflows, enabling early detection of compromise attempts. Exam questions in this space often distinguish between pipelines that rely on trust and manual checks and those that embed security and verification into the automated path, and your ability to recognize the latter is key to demonstrating mastery.
