z/OS CA Common Services for ACF2 STIG Version Comparison

There are 2 differences between versions v6 r2 (Jan. 20, 2015) (the "left" version) and v7 r2 (Oct. 1, 2025) (the "right" version).

Check ZCCSA000 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 Common Services installation datasets data sets will be properly protected.

Check Content

Refer to the following report produced by the dataset Data Set and Resource Data Collection: - SENSITVE.RPT(CCSRPT) Automated SENSITVE.RPT(CCSRPT). Automated Analysis Refer to the following report produced by the dataset Data Set and Resource Data Collection: - PDI(ZCCS0000) Verify PDI(ZCCS0000). Verify that the accesses to the CA Common Services installation datasets data sets are properly restricted. If the following guidance is true, this is not a finding. ___ finding. The 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 WRITE and/or greater access to systems programming personnel. ___ personnel. The The ACF2 dataset data set rules for the datasets data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

Discussion

CA Common Services 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 which could result in compromising the operating system or sensitive data.

Fix

The ISSO will ensure that WRITE and/or greater access to CA Common Services installation datasets data sets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users. The installing systems programmer will identify and document the product datasets, data sets and categorize them according to who will have WRITE and/or greater access access, and if required required, ensure 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 datasets, data sets, and once documented will work with the ISSO to see ensure that they are properly restricted to the ACP (Access Control Program) active on the system.
