Securing Git in DevOps: Secrets, Signing, and Hooks
Learn to keep secrets out of Git, verify authorship with signed commits, and enforce policy automatically with hooks in DevOps and automation pipelines.
Git Is a Security Surface
In DevOps, Git drives deployments. That makes the repository a security surface: a leaked secret or a forged commit can compromise production. Securing Git is part of securing the pipeline.
Keep Secrets Out of History
Never commit API keys, tokens, or passwords. Once in history, a secret is effectively public forever, even after deletion, because the old commit still contains it.
Use a .gitignore and environment variables instead.
