Fix Recommendation

The IAO will ensure that update and allocate access to NetView STC data sets are limited to System Programmers and NetView STC only, unless a letter justifying access is filed with the IAO. 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 update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update and/or alter access for specific data sets, and once documented he will work with the IAO 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>.* (VSAM data sets)

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

TSS PERMIT(CNMPROC) DSN(SYS3.netview.<systemid>.) ACCESS(R)
TSS PERMIT(audtaudt) DSN(SYS3.netview.<systemid>.) ACCESS(R)
TSS PERMIT(syspaudt) DSN(SYS3.netview.<systemid>.) ACCESS(R)
TSS PERMIT(tstcpaudt) DSN(SYS3.netview.<systemid>.) ACCESS(R)
TSS PERMIT(CNMPROC) DSN(SYS3.netview.<systemid>.) ACCESS(ALL)
TSS PERMIT(syspaudt) DSN(SYS3.netview.<systemid>.) ACCESS(ALL)
TSS PERMIT(tstcaudt) DSN(SYS3.netview.<systemid>.) ACCESS(ALL)

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
