SSL (Secure Sockets Layer) was developed by Netscape and was never formally 
standardized. TLS (Transport Layer Security) is the official IETF-standard 
replacement for SSL. TLS 1.0 is a slightly enhanced SSL 3.0.

AT-TLS (Application Transparent Transport Layer Security) is the z/OS 
Communications Server facility for adding SSL to a connection without the 
application having to know anything about SSL. You define a policy to the 
Policy Agent identifying which connections should be secured and it all works 
"magically". That's not to say that defining the policy might not be a 
challenge.
