An overview of the CICS-ESM interface

CICS® security uses, via the RACROUTE macro, the MVS™ system authorization facility (SAF) interface to route authorization requests to the ESM. Normally, if RACF® is present, the MVS router passes control to it. However, you can modify the action of the MVS router by invoking the router exit. The router exit can be used, for example, to pass control to a user-written or vendor-supplied ESM. (If you want to use your own security manager, you must supply an MVS router exit routine.)

The control points at which CICS issues a RACROUTE macro to route authorization requests are described in CICS security control points.
