STIGQter STIGQter: STIG Summary: z/OS BMC MAINVIEW for z/OS for RACF Security Technical Implementation Guide Version: 7 Release: 2 Benchmark Date: 01 Oct 2025:

BMC MAINVIEW for z/OS STC data sets are not properly protected.

Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to BMC MAINVIEW for z/OS STC data sets is limited to systems programmers and/or BMC MAINVIEW for z/OS's STC(s) and/or batch user(s) only. READ access can be given to auditors and authorized users.

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

Data sets to be protected will be:
SYS3.BMCVIEW (data sets that are altered by the product's STCs, this can be more specific)

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

ad 'SYS3.BMCVIEW.**' uacc(none) owner(sys3) -
audit(failures(read)) -
data('Vendor DS Profile: BMC MAINVIEW for z/OS')
pe 'SYS3.BMCVIEW.**' id(<syspaudt> <tstcaudt> MAINVIEW STCs) acc(a)
pe 'SYS3.BMCVIEW.**' id(<audtaudt> authorized users) acc(r)
