- `aws:PrincipalType` - This value indicates whether the principal is an account (Root credential), user (MinIO user), or assumed role (STS)
- `aws:SecureTransport` - This is a Boolean value that represents whether the request was sent over TLS.
- `aws:SourceIp` - This is the requester's IP address, for use with IP address conditions. If running behind Nginx like proxies, MinIO preserve's the source IP.
