Setting up AT-TLS
This section is provided to assist you with some common problems that you might encounter when setting up Application Transparent Transport Layer Security (AT-TLS), or during checking or modifying an existing setup.
The Transport Layer Security (TLS) protocol defined in RFC 2246 provides communications privacy over the internet. Similar to 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).

Some tasks described in the following sections expect you to be active in z/OS UNIX. This can be done by issuing the TSO command OMVS. Use the oedit command to edit files in z/OS UNIX. Use the exit command to return to TSO.
