Invoking an external security manager

CICS® provides an interface to an external security manager (ESM), which may be the Resource Access Control Facility (RACF®), a vendor product, or user-written. This section gives 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 that this section is intended primarily for non-RACF users. For definitive information about security processing using RACF, you should refer to the CICS RACF Security Guide.

The section is divided into the following sections:

  1. An overview of the CICS-ESM interface
  2. The MVS router
  3. Using ESM exit programs to access CICS-related information
  4. CICS security control points
  5. Using early verification processing.
