Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to IBM 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. The installing systems programmer will identify if any additional groups have WRITE and/or greater 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:
SYS1.ISF.AISF
SYS1.ISF.SISF

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

AD 'sys1.isf.aisf*.**' UACC(NONE) OWNER(SYS1) AUDIT(SUCCESS(UPDATE) FAILURES(READ))
AD 'sys1.isf.sisf*.**' UACC(NONE) OWNER(SYS1) AUDIT(SUCCESS(UPDATE) FAILURES(READ))

PE 'sys1.isf.aisf*.**' ID(syspaudt) ACC(A)
PE 'sys1.isf.sisf*.**' ID(syspaudt) ACC(A)
PE 'sys1.isf.sisf*.**' ID(authorized users/*) ACC(R)

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

- PDI(ZISF0000).

Verify that the accesses to the IBM SDSF installation data sets are properly restricted. If the following guidance is true, this is not a finding.

The RACF data set rules for the data sets restricts READ access to all authorized users.

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

The RACF data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

The RACF data set rules for the data sets specify UACC(NONE) and NOWARNING.
