How to secure your end-to-end supply chain on GitHub

End-to-end supply chain security is increasingly critical as threats expand to user accounts, dependencies, and build systems. GitHub has introduced comprehensive guides to assist in mitigating these risks, covering account security, code security, and build system protection. These resources emphasize the strategic implementation of security measures such as two-factor authentication, SSH keys, centralized authentication, vulnerability management for dependencies, and securing communication tokens. The guides also highlight the importance of signing builds and enhancing security for GitHub Actions. Designed for users across different plans, these guides encourage gradual improvements to reduce the risk of attacks over time, offering pathways for both beginners and advanced users to enhance their security posture.
