• INTERNAL: Developers (push/merge)
• RESTRICTED: Admins (force push, delete)

Certificate Pinning

1. Server certificates must have SHA-256 fingerprints registered in:

   # In RBACEngine initialization
   self.trusted_cert_fingerprints = {
       'fingerprint1': 'admin.example.com',
       'fingerprint2': 'git.internal.example.com'
   }
   

Audit Log Requirements

• All git operations must include:
  • HMAC-SHA256 signature
  • Timestamp verification
  • Chained hashes for tamper detection
