Fix Recommendation

Grant WRITE and/or greater access to Tivoli Asset Discovery for z/OS (TADz) STC and/or batch datasets 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 datasets 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 datasets, and assure that they are properly restricted to the ACP (Access Control Program) active on the system.

Datasets to be protected will be:
SYS3.TADZ

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

$KEY(SYS3)
TADZ.- UID(syspaudt) R(A) W(A) A(A) E(A)
TADZ.- UID(audtaudt) R(A) E(A)
TADZ.-.UM.- UID(batchid TADZINQ) R(A) W(A) A(A) E(A)
TADZ.-.IQ.- UID(batchid TADZINQ) R(A) W(A) A(A) E(A)
TADZ.-.UIQ.- UID(batchid TADZINQ) R(A) W(A) A(A) E(A)
TADZ.- UID(stc id TADZMON) R(A) W(A) A(A) E(A)
