Fix Recommendation

Grant WRITE and/or greater access to Tivoli Asset Discovery for z/OS (TADz) STC and/or batch data sets are limited to systems programmers and TADz STC and/or batch jobs only.

Grant READ access to any scheduling products that are in use.

Grant READ access to auditors at the ISSO's discretion.

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. Identify if any additional groups have UPDATE access for specific data sets, and assure that they are properly restricted to the Access Control Program (ACP) active on the system.

Data sets to be protected will be:
SYS3.TADZ

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

TSS PERMIT(syspaudt) DSN(sys3.tadz.*.iq*.) ACCESS(R)
TSS PERMIT(tadzmon) DSN(sys3.tadz.*.iq*.) ACCESS(R)
TSS PERMIT(tadzinq) DSN(sys3.tadz.*.iq*.) ACCESS(R)
TSS PERMIT(syspaudt) DSN(sys3.tadz.*.iq*.) ACCESS(ALL)
TSS PERMIT(tadzmon) DSN(sys3.tadz.*.iq*.) ACCESS(ALL)
TSS PERMIT(tadzinq) DSN(sys3.tadz.*.iq*.) ACCESS(ALL)

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZTAD0001).

Verify that access to the TADz STC and/or batch 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 restrict WRITE and/or greater access is restricted to systems programming personnel and the product STC(s) and/or batch job(s).

The TSS data set rules for the data sets restrict READ access is restricted to any job scheduling products that are in use and auditors.
