Github Enterprise

The following should serve as a basic checklist list for reviewing Github Enterprise deployments. It'll largely apply to Github Organizations on github.com too.

Authentication

• What authentication mechanism is being used?
• Are built-in users allowed too?
  • Allowing built-in authentication for users outside your identity provider - GitHub Help
• Is two factor authentication (2FA) enforced?
  • About two-factor authentication - GitHub Help
  • Requiring two-factor authentication for an organization - GitHub Help
  • Not supported for SAML or CAS; Github Enterprise trusts the IdP's assertions as to authentication, and thus 2FA needs to be enforced at the IdP
• check the user audit log
  • Auditing users across your instance - GitHub Help

Authorisation

• Is an Administrators group defined if using federation? If so, who are the members?
• What's the permissions model like for repositories?
  • Repository permission levels for an organization - GitHub Help
• What's the default repository visibility?
  • Configuring the default visibility of new repositories on your appliance - GitHub Help

Logging

• Is log forwarding enabled?
  • Log forwarding - GitHub Help
• is collectd enabled?
  • Configuring collectd - GitHub Help
• How's audit logging working? Audit logging - GitHub Help

Services

• Are pages enabled? This can potentially be problematic if public pages are enabled because the websites become available to unauthenticated users too
• Is LFS enabled?
  • Configuring Git Large File Storage - GitHub Help

Webhooks

• Check webhook configurations in use
  • Continuous integration using Jenkins - GitHub Help
• Are any global webhooks enabled?
  • Managing global webhooks - GitHub Help
