Description
NetView STC datasets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their datasets 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 dataset and Resource Data Collection: - SENSITVE.RPT(NETVSTC). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZNET0001). Verify that access to the NetView STC datasets is properly restricted. If the following guidance is true, this is not a finding. The ACF2 dataset rules for the datasets restrict READ access to auditors. The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to systems programming personnel. The ACF2 dataset rules for the datasets restrict 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 datasets is limited to systems 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 datasets, categorize them according to who will have WRITE and/or greater access, and if required, ensure that all WRITE and/or greater access is logged. The systems programmer will identify if any additional groups have WRITE and/or greater access for specific datasets, and once documented he will work with the ISSO to ensure that they are properly restricted to the ACP (Access Control Program) active on the system. Datasets to be protected will be: SYS3.NETVIEW.<SYSTEMID>.- (VSAM datasets) The following commands are provided as a sample for implementing dataset controls: SET RULE $KEY(SYS3) NETVIEW.<systemid>.- UID(audtaudt) R(A) E(A) NETVIEW.<systemid>.- UID(cnmproc) R(A) W(A) A(A) E(A) NETVIEW.<systemid>.- UID(syspudt) R(A) W(A) A(A) E(A) NETVIEW.<systemid>.- UID(tstcaudt) R(A) W(A) A(A) E(A) The VSAM dataset required for greater than READ access are: SYS3.NETVIEW.<systemid>.AAUVSPL SYS3.NETVIEW.<systemid>.AAUVSSL SYS3.NETVIEW.<systemid>.BNJLGPR SYS3.NETVIEW.<systemid>.BNJLGSE SYS3.NETVIEW.<systemid>.BNJ36PR SYS3.NETVIEW.<systemid>.BNJ36SE SYS3.NETVIEW.<systemid>.DSIKPNL SYS3.NETVIEW.<systemid>.DSILIST SYS3.NETVIEW.<systemid>.DSILOGP SYS3.NETVIEW.<systemid>.DSILOGS SYS3.NETVIEW.<systemid>.DSISVRT SYS3.NETVIEW.<systemid>.DSITRCP SYS3.NETVIEW.<systemid>.DSITRCS SYS3.NETVIEW.<systemid>.SDSIOPEN
