gthen Access Controls

Implementing proper access control is one of the best practices for enhancing security, not only on GitHub but in every other environment where code security is imperative.

GitHub offers several options that users can employ to reduce the risk of improper exposure. But to start with, it is important to employ the least privilege model where users are only granted necessary permissions.

Here are some basic access control guidelines that you should follow:

• Restrict the creation of repositories to prevent users from exposing organization information in public repositories.
• Enable branch protection and status checks to ensure users can merge commits or manipulate branches safely.
• Allow or disallow forking private repositories to ensure users do not expose or share organizational code with unauthorized parties.
• Revoke access for all inactive users who are no longer part of the contributors.
• Review access rights to your GitHub projects periodically.
• Ensure users do not share GitHub accounts or passwords.
• Ensure every contributor uses two-factor authentication on their account.
• Rotate personal access tokens and SSH keys

Never Store Credentials in Your GitHub Files

Leaking secrets to your GitHub repositories, either through code, configuration files, or commit messages, provides a gateway for attacks.
