The IAO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resource type, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource type, 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.) Ensure that all Sensitive Utility Controls resources and/or generic equivalent are properly protected according to the requirements specified in Sensitive Utility Controls table in the z/OS STIG Addendum. Use Sensitive Utility Controls table in the z/OS STIG Addendum. This table lists the resources, access requirements, and logging requirements for Sensitive Utilities, ensures the following guidelines are followed: The ACF2 resources are defined with a default access of PREVENT.
