Harden CICD Pipeline

Category: Engineering  ·  Sub-category: devops  ·  Last updated:
tool:gitlabtype:audit
Defensive methodology for CI/CD pipeline compromise: expression and workflow injection that turns attacker-controlled PR titles, branch names, and issue bodies into runner command execution, over-broad OIDC federation that hands the wrong repo or branch cloud credentials, and self-hosted runner abuse (MITRE ATT&CK T1195.002, T1059, T1199, T1078.004, T1552.004, T1098.001). Signals live in the GitHub/GitLab/Azure DevOps audit log, runner process and EDR telemetry, and cloud federation logs (AWS CloudTrail AssumeRoleWithWebIdentity, Entra ID service-principal sign-ins, GCP STS). Gives the defender view, what to log and alert on, a hunt, and OIDC, runner-isolation, and workflow-injection hardening. Use when hardening GitHub Actions, GitLab CI, or Azure Pipelines, reviewing an OIDC trust policy, hunting for poisoned pipeline execution, triaging an unexpected AssumeRoleWithWebIdentity, or isolating self-hosted runners.
