Setting up AT-TLS
The information in this section shows how to set up the TCP/IP Policy Agent that manages Application Transparent Transport Layer Security (AT-TLS) and define a policy for usage by z/OS® Explorer.
The Transport Layer Security (TLS) protocol defined in RFC 2246 provides communications privacy
over the internet. Like its predecessor Secure Socket Layer (SSL), the protocol enables client and
server applications to communicate in a way that is designed to prevent eavesdropping, tampering,
and message forgery. Application Transparent Transport Layer Security (AT-TLS) consolidates TLS
implementation for z/OS-based applications in one location,
allowing all applications to support TLS-based encryption without knowledge of the TLS protocol. For
more information on AT-TLS, see Communications Server IP Configuration Guide
(SC31-8775).
Note: RSE supports only the AT-TLS aware application mode.
