Discussion

Tivoli Asset Discovery for z/OS (TADz) Install data sets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their data sets could result in violating the integrity of the base product product, which could result in compromising the operating system or sensitive data.

Fix

The IAO ISSO will ensure that update and allocate/create access to program product data sets is limited to System system Programmers programmers only, and all update and allocate/create access is logged. Auditors should have read access. The installing Systems systems Programmer programmer will identify and document the product data sets and categorize them according to who will have update and allocate/create access and if required that all update and allocate/create access is logged. He The installing systems programmer will identify if any additional groups have update access for specific data sets, and once documented documented, he will work with the IAO ISSO to ensure see that they are properly restricted to the ACP (Access Access Control Program ) (ACP) active on the system. Data sets to be protected will be: SYS2.TADZ SYS2.TADZ .V-.SHSIMOD1 (optional fully-qualified APF).
