Security for EXCI

CICS® applies security checks in a number of ways against requests received from an MVS™ client program.

Using MRO logon and bind-time security
DFHIRP, the CICS interregion communication program, performs two security checks against users that want to either log on to IRP (specific connections only), or connect to a CICS region (also referred to as bind-time security).
Link security
The target CICS server region performs link security checking against requests from the client program.
User security
The target CICS server region performs user security checking against the user ID passed on a DPL_ Request call. User security checking is performed only when connections specify ATTACHCSEC(IDENTIFY).
Surrogate user checking
A surrogate user check is performed to verify that the batch region's user ID is authorized to issue DPL calls for another user (that is, is authorized as a surrogate of the user ID specified on the DPL_Request call).
