Fix Recommendation

The ISSO must ensure that WRITE and/or greater access to BMC CONTROL-D User datasets is limited to systems programmers and BMC STCs and/or batch users. Additionally, UPDATE access can be given to centralized and decentralized security personnel and BMC users. The ISSO can approve ALLOC access in circumstances where it is determined to be necessary and appropriate for systems operations to execute in a normal secure manner. READ access can be given to auditors.

The installing systems programmer will identify and document the product datasets, categorize them according to who will have WRITE and/or greater access, and if required, ensure that all WRITE and/or greater access is logged. The installing systems programmer must identify if any additional groups have WRITE and/or greater access for specific datasets, and once documented will work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program) active on the system.

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

Datasets to be protected will be:
SYS3.IOA.*.CTDR
CTRUSR
CTDSRV
CTDJB1

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