Fix Recommendation

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

(Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The resource class, 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.)

Ensure all IBM SDSF resources are properly protected according to the requirements specified in the SSP. The plan should be based on the SDSF SAF Resources table in the z/OS STIG Addendum and validated by the site ISSO.

Use SDSF SAF Resources and SDSF SAF Resource Descriptions tables in the zOS STIG Addendum/SSP. These tables list the resources and access requirements for IBM SDSF; ensure the following guidelines are followed:

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

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

The TSS resource logging is specified as designated in the table above.

The TSS resource access authorizations for SDSF GROUP.group-name will require additional analysis to justify access.

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

TSS ADD(dept-acid) SDSF(ISFATTR)
TSS PERMIT(operaudt) SDSF(ISFATTR.JOBCL) ACCESS(UPDATE)
TSS PERMIT(syspaudt) SDSF(ISFATTR.JOBCL) ACCESS(UPDATE)
