Keeping your account and data secure
To protect your personal information, you should keep both your GitHub Enterprise Server account and any associated data secure.
About authentication to GitHub
You can securely access your account's resources by authenticating to GitHub Enterprise Server, using different credentials depending on where you authenticate.
Creating a strong password
Secure your GitHub Enterprise Server account with a strong and unique password using a password manager.
Updating your GitHub access credentials
GitHub Enterprise Server credentials include not only your password, but also the access tokens, SSH keys, and application API tokens you use to communicate with GitHub Enterprise Server. Should you have the need, you can reset all of these access credentials yourself.
Creating a personal access token
You should create a personal access token to use in place of a password with the command line or with the API.
Reviewing your SSH keys
To keep your credentials secure, you should regularly audit your SSH keys, deploy keys, and review authorized applications that access your GitHub Enterprise Server account.
Reviewing your deploy keys
You should review deploy keys to ensure that there aren't any unauthorized (or possibly compromised) keys. You can also approve existing deploy keys that are valid.
Authorizing OAuth Apps
You can connect your GitHub Enterprise Server identity to third-party applications using OAuth. When authorizing an OAuth App, you should ensure you trust the application, review who it's developed by, and review the kinds of information the application wants to access.
Authorizing GitHub Apps
You can authorize a GitHub App to allow an application to retrieve information about your GitHub account and, in some circumstances, to make changes on GitHub on your behalf.
Reviewing your authorized integrations
You can review your authorized integrations to audit the access that each integration has to your account and data.
Connecting with third-party applications
You can connect your GitHub Enterprise Server identity to third-party applications using OAuth. When authorizing one of these applications, you should ensure you trust the application, review who it's developed by, and review the kinds of information the application wants to access.
Reviewing your authorized applications (OAuth)
You should review your authorized applications to verify that no new applications with expansive permissions are authorized, such as those that have access to your private repositories.
Reviewing your security log
You can review the security log for your user account to better understand actions you've performed and actions others have performed that involve you.
Removing sensitive data from a repository
If you commit sensitive data, such as a password or SSH key into a Git repository, you can remove it from the history. To entirely remove unwanted files from a repository's history you can use either the
git filter-branchcommand or the BFG Repo-Cleaner open source tool.
GitHub Enterprise Server asks you for your password before you can modify your email address, authorize third-party applications, or add new public keys, or initiate other sudo-protected actions.
Preventing unauthorized access
You may be alerted to a security incident in the media, such as the discovery of the Heartbleed bug, or your computer could be stolen while you're signed in to your GitHub Enterprise Server instance. In such cases, changing your password prevents any unintended future access to your account and projects.
