z/OS CA VTAPE for ACF2 STIG Version Comparison

There are 3 differences between versions v6 r5 (Nov. 23, 2022) (the "left" version) and v7 r2 (Oct. 1, 2025) (the "right" version).

Check ZVTAA000 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

CA VTAPE installation datasets data sets are not properly protected.

Check Content

Refer to the following report produced by the dataset Data Set and Resource Data Collection: - Collection: - SENSITVE.RPT(VTARPT) Automated SENSITVE.RPT(VTARPT). Automated Analysis Refer to the following report produced by the dataset Data Set and Resource Data Collection: - PDI(ZVTA0000) Verify Collection: - PDI(ZVTA0000). Verify that the accesses to the CA VTAPE installation datasets data sets are properly restricted. ___ The restricted. If the following guidance is true, this is not a finding. The ACF2 dataset data set rules for the datasets data sets restricts restrict READ access to all authorized users. ___ The users. The ACF2 dataset data set rules for the datasets data sets restricts restrict UPDATE WRITE and/or ALTER greater access to systems programming personnel. ___ The personnel. The ACF2 dataset data set rules for the datasets data sets specify that all (i.e., failures and successes) UPDATE WRITE and/or ALTER greater access are is logged.

Discussion

CA VTAPE installation datasets data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these datasets 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 WRITE and/or greater access to CA VTAPE installation datasets data sets is limited to System systems Programmers programmers only, and all update and allocate WRITE and/or greater access is logged. READ Read access can be given to all authorized users. The installing Systems systems Programmer programmer will identify and document the product datasets, data sets and categorize them according to who will have update and alter WRITE and/or greater access access, and if required required, ensure that all update and allocate WRITE and/or greater access is logged. He The installing systems programmer will identify if any additional groups have update WRITE and/or alter greater access for specific datasets, 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 system. Datasets sets to be protected will be: SYS2.VTAPE.
