Fix Text (F-442r1_fix)
The IAO will ensure that read, update, and alter access to program product user data sets is limited to System Programmers, Security Personnel, and Auditors and all update and alter 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 alter 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.VSS. The above prefix can specify specific data sets, these would include the VSAM and JCL data sets. The following commands are provided as a sample for implementing dataset controls: ad 'sys3.vss.' uacc(none) owner(sys3) - audit(success(update) failures(read)) - data('Site Customized DS Profile: Vanguard Security Solutions') pe 'sys3.vss.' id(syspaudt secaaudt audtaudt) acc(a)
