Transport Layer Security
Transport Layer Security (TLS) describes how to use TLS on your system.
Secure Sockets Layer (SSL) and TLS are generic terms for a set of industry standards that are used for enabling applications for secure communication sessions over an unprotected network, such as the Internet. SSL evolved into and was replaced by TLS. TLS is the more accurate term; therefore, TLS is used throughout this topic.
The version of the TLS protocol specification identifies the relative level of security provided. No version of the SSL protocol specification should be used today. Not all versions of the TLS protocol are allowed for security compliance in some industries.
