Fix Recommendation

The IAO will ensure that read, update, and allocate access to program product user data sets is limited to System Programmers, Security Personnel, and Auditors and all update and allocate access is logged.

The installing System Programmer will identify and document the product user data sets and categorize them according to who will have update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update access for specific data sets, and once documented he will work with the IAO to see that they are properly restricted to the ACP (Access Control Program ) active on the system.

Data set prefix to be protected will be:

SYS3.SRRAUDIT.

If doing a full SRR review using the z/OS STIG Instruction, the following data set prefix to be protected will be:

SYS3.FSO.

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