Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to NetView install data sets is limited to systems programmers only, and all WRITE and/or greater access is logged. All other users can 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. The installing systems programmer will identify if any additional groups have UPDATE access for specific data sets, and once documented will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system.

Data sets to be protected will be:
SYS2.NETVIEW
SYS2A.NETVIEW
SYS3.NETVIEW

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

TSS PERMIT(syspaudt) DSN(SYS2.netview.) ACCESS(r)
TSS PERMIT(syspaudt) DSN(SYS2.netview.) ACCESS(all) ACTION(AUDIT)

TSS PERMIT(syspaudt) DSN(SYS2a.netview.) ACCESS(r)
TSS PERMIT(syspaudt) DSN(SYS2a.netview.) ACCESS(all) ACTION(AUDIT)

TSS PERMIT(syspaudt) DSN(SYS3.netview.) ACCESS(r)
TSS PERMIT(syspaudt) DSN(SYS3.netview.) ACCESS(all) ACTION(AUDIT)

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZNET0000).

Verify that access to the NetView install data sets are properly restricted. If the following guidance is true, this is not a finding.

The TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel.

The TSS data set rules for the data sets do not specify that all (i.e., failures and successes) WRITE and/or greater access will be logged.
