Transport Layer Security (TLS) is the successor to the Secure Sockets Layer (SSL) protocol. Both communication protocols provide network security to client-server applications.
For general information on how to implement TLS or SSL, refer to https://technet.microsoft.com/en-us/library/cc784450(v=ws.10).aspx.
The Metasys software can use Secure Channel and built-in implementation of TLS or SSL included with the Microsoft Windows operating system. For more information about Secure Channel, refer to https://msdn.microsoft.com/en-us/library/windows/desktop/aa380123(v=vs.85).aspx.
