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

Use BMC MAINVIEW Resources table in the z/OS STIG Addendum. This table lists the resources, access requirements, and logging requirement for BMC MAINVIEW. Ensure the guidelines for the resource type, resources, and/or generic equivalent specified in the z/OS STIG Addendum are followed.

The ACF2 resources as designated in the above table are defined with a default access of PREVENT.

The ACF2 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:

$KEY(BBM) TYPE(BMV)
ssid.CN UID(autoaudt) ALLOW
ssid.CN UID(dasdaudt) ALLOW
ssid.CN UID(mqsaaudt) ALLOW
ssid.CN UID(Mainview STCs) ALLOW
ssid.CN UID(mvzread) ALLOW
ssid.CN UID(mvzupdt) ALLOW
ssid.CN UID(pcspaudt) ALLOW
ssid.CN UID(syspaudt) ALLOW
- UID(*) PREVENT
