Fix Recommendation

The ISSO will work with the systems programmer to verify that the following are properly specified in the Access Control Program (ACP).

Note: To determine what resource class is used review the IOACLASS setting in SECPARM. The "Trigger" resources i.e., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class.


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

Use BMC IOA Resources and BMC INCONTROL Resources Descriptions tables in the zOS STIG Addendum. These tables list the resources, descriptions, and access and logging requirements. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed.

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

TSS ADD(ADMIN) IOA($$ADDCND)
TSS PERMIT(<autoaudt>) IOA($$ADDCND) ACC(ALL)
TSS PERMIT(<operaudt>) IOA($$ADDCND) ACC(ALL)
TSS PERMIT(<pcspaudt>) IOA($$ADDCND) ACC(ALL)
TSS PERMIT(<prodaudt>) IOA($$ADDCND) ACC(ALL)
TSS PERMIT(<syspaudt>) IOA($$ADDCND) ACC(ALL)

Check Contents

Refer to the following report produced by the Data Set and Resource Data Collection:

- SENSITVE.RPT(ZIOA0020).

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZIOA0020).

Verify that the accesses to resources and/or generic equivalent are properly restricted according to the requirements specified in BMC IOA Resources table in the z/OS STIG Addendum. If the following guidance is true, this is not a finding.

Note: To determine what resource class is used review the IOACLASS setting in SECPARM. The "Trigger" resources i.e., $$SECxxx (xxx is unique to the product) are defined in the FACILITY resource class.

The TSS resources are owned or DEFPROT is specified for the resource class.

The TSS resource access authorizations restrict access to the appropriate personnel.

The TSS resource logging requirements are specified.
