  • Secure Sockets Layer (SSL) is enhanced by transport securityLayer 1 (TLS) whenever a protocol is used to provide data transfer between computer systems. They are so closely related that the “SSL” and “TLS” (no versions) rules are perhaps often used interchangeably. Because of the similarity of advice, references to “SSL” in the Exchange, Exchange Center, Administration, and therefore Exchange Management Shell sections are regularly used to cover both the entire SSL protocol and the TLS protocol. Generally, “SSL” only refers to the actual SSL protocol if its version is specified (for example, SSL 3.0). To learn why you should remove SSL and switch to TLS, read Defending Against the SSL 3.0 Vulnerability.
