STIGQter STIGQter: STIG Summary: z/OS BMC MAINVIEW for z/OS for TSS 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 Access Control Program (ACP) 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:

TSS PERMIT(<syspaudt>) DSN(SYS3.BMCVIEW) ACCESS(ALL)
TSS PERMIT(<tstcaudt>) DSN(SYS3.BMCVIEW) ACCESS(ALL)
TSS PERMIT(MAINVIEW STCs) DSN(SYS3.BMCVIEW) ACCESS(ALL)
TSS PERMIT(<audtaudt>) DSN(SYS3.BMCVIEW) ACCESS(R)
TSS PERMIT(authorize user) DSN(SYS3.BMCVIEW) ACCESS(R)

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZMVZ0001).

Verify that the accesses to the BMC MAINVIEW for z/OS STC data sets are properly restricted. If the following guidance is true, this is not a finding.

The TSS data set rules for the data sets restrict READ access to auditors and authorized users.

The TSS data set rules for the data sets restrict UPDATE and/or ALL access to systems programming personnel.

The TSS data set rules for the data sets restrict UPDATE and/or ALL access to the BMC MAINVIEW for z/OS's STC(s) and/or batch user(s).
