Invoking an external security manager

CICS® provides an interface to an external security manager (ESM), which can be the Resource Access Control Facility (RACF®), a vendor product, or user-written. This information provides an overview of the CICS-ESM interface, and describes how you can use the MVS™ router exit to pass control to a user-written ESM. It describes how ESM exit programs can access CICS-related information. Finally, it lists the control points at which CICS invokes the ESM.

Note: This information is intended primarily for non-RACF users. For definitive information about security processing using RACF, refer to RACF facilities.
