The authentication protects against man-in-the-middle attacks and the privacy prevents attackers to eavesdrop and tamper on the communication. In that way, it servers two purposes: authentication (to know who the remote party is you connect to) and privacy (the encryption). It does create this secure channel by the use of a TLS certificate that is exchanged in the TLS handshake. Hypertext Transfer Protocol Secure (HTTPS) is a secure communication protocol which uses Transport Layer Security (TLS) to encrypt the communication. This change can lead to MRA login failures after an upgrade on your Expressway platform. With this change of behavior marked by Cisco bug ID CSCwc69661 or Cisco bug ID CSCwa25108, the traffic server on the Expressway platform performs certificate verification of the Cisco Unified Communication Manager (CUCM), Cisco Unified Instant Messaging & Presence (IM&P) and Unity server nodes for the Mobile and Remote Access (MRA) services. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
