Fix Recommendation

The IAO will ensure that WRITE and/or greater access to IBM System Display and Search Facility (SDSF) installation data sets is limited to System Programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users.

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 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.ISF.AISF
SYS1.ISF.SISF

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

$KEY(S1I)
$PREFIX(SYS1)
ISF.AISF-.- UID(syspaudt) R(A) W(L) A(L) E(A)
ISF.SISF-.- UID(syspaudt) R(A) W(L) A(L) E(A)
ISF.SISF-.- UID(authorized users/*) R(A) E(A)
