Enforcing policies for security settings in your enterprise

About policies for security settings in your enterprise

You can enforce policies to control the security settings for organizations owned by your enterprise on GitHub AE. By default, organization owners can manage security settings.

Managing SSH certificate authorities for your enterprise

You can use a SSH certificate authorities (CA) to allow members of any organization owned by your enterprise to access that organization's repositories using SSH certificates you provide. You can require that members use SSH certificates to access organization resources, unless SSH is disabled in your repository. For more information, see "About SSH certificate authorities."

When you issue each client certificate, you must include an extension that specifies which GitHub AE user the certificate is for. For more information, see "About SSH certificate authorities."

Adding an SSH certificate authority

If you require SSH certificates for your enterprise, enterprise members should use a special URL for Git operations over SSH. For more information, see "About SSH certificate authorities."
