New workload

For new applications, security can be built-in. One method of building security into the application on z/OS® is to use z/OS System SSL and Kerberos. Another method is to use the Communication Server's policy-driven Application Transparent Transport Layer Security (AT-TLS), which requires no change to the application unless the application must control certain portions of the AT-TLS support.

Tip: Using AT-TLS is highly recommended over the direct use of System SSL.

Newer versions of network services, such as SNMPv3 that are supported by the Communications Server, have security built into the application protocol using standards-based specifications for secure interoperability.
