Advanced GitHub Security Best Practices [Cheat Sheet]
After reading this cheat sheet, you’ll be able to:
Secure GitHub authentication with MFA, SSO, and hardened key/token management.
Protect GitHub organizations and repositories with RBAC, branch protection, and fine-grained rulesets.
Lock down GitHub Actions workflows against supply chain attacks and privilege escalation.
Monitor and audit GitHub activity with logs, webhooks, and SIEM integrations.
Apply modern DevSecOps practices to safeguard GitHub pipelines and reduce software supply chain risk.
Key Takeaways
- GitHub is a top target for attackersWith its central role in modern software development, securing GitHub is critical to protecting both open-source and proprietary code.
- Strong authentication is non-negotiableMFA, SSO, and hardened key/token management form the first line of defense against compromised accounts.
- Misconfigurations create the biggest risksWeak defaults, ungoverned third-party apps, and lax branch protections can quickly expose your organization to supply chain threats.
- Security must extend to CI/CD workflowsHardening GitHub Actions, pinning dependencies, and isolating untrusted code are essential for preventing pipeline exploitation.
