WS Authentication and Authorization Message-Level Security implements the WS-Security standard and the WS-SecureConversation specification to provide message protection for SOAP messages. Features include authentication of the sender, encryption of the message, integrity protection of the message and replay protection.

WS Authentication and Authorization Transport-Level Security provides a secure channel by using HTTP over SSL/TLS (HTTPS) for transporting the messages. This security mechanism supports all of the security features provided by SSL/TLS with the addition of support for X.509 Proxy Certificates.
