Description
SRRAUDIT User data sets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.

Fix Text (F-27295r472621_fix)
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 allocate 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.
