Description
Compuware Abend-AID STC 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 which could result in compromising the operating system or sensitive data.

Verify that the accesses to the Compuware Abend-AID 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 restricts READ access to auditors.

___ The TSS data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel.

___ The TSS data set rules for the data sets restricts WRITE and/or greater access to the Compuware Abend-AID's STC(s) and/or batch user(s).

Fix Text (F-26332r868604_fix)
The ISSO will ensure that WRITE and/or greater access to Compuware Abend-AID STC data sets is limited to systems programmers and/or Compuware Abend-AID's STC(s) and/or batch user(s) only. READ access can be given to auditors. 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.ABENDAID. The following commands are provided as a sample for implementing data set controls: TSS ADD(SYS3) DSN(SYS3) TSS PERMIT(syspaudt) DSN(SYS3.ABENDAID.) ACCESS(ALL) TSS PERMIT(ABEND-AID STCs) DSN(SYS3.ABENDAID.) ACCESS(ALL) TSS PERMIT(audtaudt) DSN(SYS3.ABENDAID) ACCESS(READ)
