Fix Recommendation

Configure ACP resource definitions in accordance with Vanguard Security Solutions Resources and Vanguard Security Solutions Resources Descriptions tables in the z/OS 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.

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

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

rdef facility vra$.acstask.** uacc(none) owner(admin) -
audit(all(read)) -
data('protected per zvssr020')

pe vra$.acstask.** cl(facility) id(<audtaudt>) acc(read)
pe vra$.acstask.** cl(facility) id(<secaaudt>) acc(read)
Sample scope definition:
rdef facility vsr$.** uacc(none) owner(admin) audi(a(r)) -
data('deny-by-default for Vanguard Advisor Reporter')
rdef facility vsr$.scope uacc(none) owner(admin) -
audit(a(u)) data('Vanguard Advisor Reporter Auth Scope')
