Security support

CICS® Transaction Server for z/OS® supports: a single network signon, and authentication of the client system through bind-time security.

Single network signon is supported through the ATTACHSEC option of the DEFINE CONNECTION command.

RACF® or an equivalent security manager provides mechanisms similar to the DCE access control lists and login facility.

There is no CICS concept similar to the DCE Directory Service. In all the previous scenarios the client environment must know which server CICS system to communicate with. This is normally done by specifying the name of the required remote CICS system in the definition of the relevant remote CICS resource, or in the client application program.
