z/OS BMC MAINVIEW for z/OS for ACF2 STIG Version Comparison

There are 4 differences between versions v6 r9 (April 27, 2022) (the "left" version) and v7 r1 (April 2, 2025) (the "right" version).

Check ZMVZA000 was changed between these two versions. Green, underlined text was added, red, struck-out text was removed.

The regular view of the left check and right check may be easier to read.

Title

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

The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) UPDATE and/or ALTER access are logged.

Discussion

BMC MAINVIEW for z/OS installation data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product product, which could result in compromising the operating system or sensitive data.

Fix

The IAO ISSO will ensure that update and allocate access to BMC MAINVIEW for z/OS installation data sets is limited to System system Programmers programmers only, and all update and allocate access is logged. Read access can be given to all authorized users. The installing Systems systems Programmer programmer will identify and document the product data sets and categorize them according to who will have update and alter access access, and if required required, that all update and allocate access is logged. He The programmer will identify if any additional groups have update and/or alter access for specific data sets, and once documented documented, he will work with the IAO ISSO to ensure see that they are properly restricted to the ACP (Access Access Control Program) Program (ACP) active on the system. Data sets to be protected will be: SYS2.BMCVIEW. SYS3.BMCVIEW. (data sets that are not altered by product STCs, can be more specific) The following commands are provided as a sample for implementing data set controls: $KEY(SYS2) BMCVIEW.- UID(<syspaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(authorized users) R(A) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(MAINVIEW STCs) R(A) E(A) $KEY(SYS3) BMCVIEW.- UID(<syspaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) BMCVIEW.- UID(<audtaudt>) R(A) E(A) BMCVIEW.- UID(authorized users) R(A) E(A) BMCVIEW.- UID(MAINVIEW STCs) R(A) E(A)
