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 resource prefixes are determined when the product is installed on a system through the product's installation guide and can be site-specific.)

Ensure that all IBM SDSF resources are properly protected according to the requirements specified in the Site Security Plan (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 z/OS STIG Addendum/SSP. These tables list the resources and access requirements for IBM SDSF; ensure the following guidelines are followed:

The ACF2 resources and/or generic equivalent as designated in the above table are defined with a default access of NONE.

The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The ACF2 resource logging is specified as designated in the above table.

The ACF2 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:

$KEY(ISFATTR) TYPE(SDS)
JOBCL.- UID(operaudt) SERVICE(READ,UPDATE) ALLOW
JOBCL.- UID(syspaudt) SERVICE(READ,UPDATE) ALLOW
- UID(*) PREVENT

Verify all IBM SDSF resources are properly protected according to the requirements specified in the Site Security Plan (SSP). The plan should be based on the SDSF SAF Resources table in the z/OS STIG Addendum and validated by the site ISSO. If the following guidance is true, this is not a finding.

The ACF2 resources and/or generic equivalent as designated in the above table are defined with a default access of NONE.

The ACF2 resource access authorizations restrict access to the appropriate personnel as designated in the above table.

The ACF2 resource logging is specified as designated in the above table.

The ACF2 resource access authorizations for SDSF GROUP.group-name will require additional analysis to justify access.
