Fix Recommendation

The IAO will ensure that update and ALL access to IBM Hardware Configuration Definition (HCD) install data sets is limited to System Programmers only, and all update and ALL access is logged. Auditors, automated operations, and operators 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 ALL access and if required that all update and ALL access is logged. He will identify if any additional groups have update and/or ALL 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:
SYS1.SCBD*

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

TSS PERMIT(audtaudt) DSN(SYS1.SCBD) ACCESS(R)
TSS PERMIT(autoaudt) DSN(SYS1.SCBD) ACCESS(R)
TSS PERMIT(operaudt) DSN(SYS1.SCBD) ACCESS(R)
TSS PERMIT(syspaudt) DSN(SYS1.SCBD) ACCESS(R)
TSS PERMIT(tstcaudt) DSN(SYS1.SCBD) ACCESS(R)
TSS PERMIT(syspaudt) DSN(SYS1.SCBD) ACCESS(ALL) ACTION(AUDIT)
TSS PERMIT(tstcpaudt) DSN(SYS1.SCBD) ACCESS(ALL) ACTION(AUDIT)
