Description
NetView STC 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 which could result in compromising the operating system or sensitive data.

ℹ️ Check
Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(NETVSTC). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZNET0001). Verify that access to the NetView STC data sets are properly restricted. If the following guidance is true, this is not a finding. The RACF data set rules for the data sets restricts READ access to auditors. The RACF data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. The RACF data set rules for the data sets restricts WRITE and/or greater access to the product STC(s) and/or batch job(s).

✔️ Fix
The ISSO will ensure that WRITE and/or greater access to NetView STC data sets are limited to System Programmers and NetView STC only, unless a letter justifying access is filed with the ISSO. Auditors should have READ access. 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. He will identify if any additional groups have WRITE and/or greater access for specific data sets, and once documented he will work with the ISSO to see that they are properly restricted to the ACP (Access Control Program) active on the system. Data sets to be protected will be: SYS3.NETVIEW.<systemid>.
