Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to CA Auditor User data sets are limited to systems programmers, security personnel, and 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 Access Control Program (ACP) active on the system.

Data sets to be protected will be:

SYS3.EXAMINE

The following commands are provided as a sample for implementing data set controls:

TSS PERMIT(<syspaudt>) DSN(SYS3.EXAMINE) ACCESS(ALL)
TSS PERMIT(<audtaudt>) DSN(SYS3.EXAMINE) ACCESS(ALL)
TSS PERMIT(<secaaudt>) DSN(SYS3.EXAMINE) ACCESS(ALL)
