Fix Recommendation

The IAO will work with the systems programmer to verify that the following are properly specified in the ACP.

(Note: The resources and/or resource prefixes identified below are examples of a possible installation. The actual resources and/or prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.)

Use CA MIM Resource Sharing Resources table in the zOS STIG Addendum. This table list the resources, access requirements, and logging requirement for CA MIM Resource Sharing. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed.

Note: SAFPREFIX identifies the prefix for all resources. The default value for this keyword parameter is MIMGR. It is coded in the MIMINIT member of the data set specified in the MIMPARMS DD statement of the started task procedures.

The TSS resources as designated in the above table are owned and/or DEFPROT is specified for the resource class.

The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The following commands are provided as a sample for implementing resource controls:

TSS ADD(dept-acid) OPERCMDS(prefix)
TSS PERMIT(syspaudt) OPERCMDS(prefix.ACTIVATE) ACCESS(UPDATE)
