Fix Recommendation

The IAO will ensure that update and alter access to program product install data sets is limited to System Programmers, and read access is limited to Security personnel and Auditors, and all update and allocate access is logged.

The installing System 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 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 set prefix to be protected will be:

SYS2.VSS.
SYS2A.VSS.
SYS3.VSS.VANOPTS

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

ad 'sys2.vss.**' uacc(none) owner(sys2) -
audit(success(update) failures(read)) -
data('Vendor DS Profile: Vanguard Security Solutions')
pe 'sys2.vss.**' id(syspaudt) acc(a)
pe 'sys2.vss.**' id(secaaudt secdaudt audtaudt) acc(r)

ad 'sys2a.vss.**' uacc(none) owner(sys2a) -
audit(success(update) failures(read)) -
data('Vendor Loadlib: Vanguard Security Solutions')
pe 'sys2a.vss.**' id(syspaudt) acc(a)
pe 'sys2a.vss.**' id(secaaudt secdaudt audtaudt) acc(r)

ad 'sys3.vss.vanopts.**' uacc(none) owner(sys3) -
audit(success(update) failures(read)) -
data('Site Customized DS Profile: Vanguard Security Solutions')
pe 'sys3.vss.vanopts.**' id(syspaudt) acc(a)
pe 'sys3.vss.vanopts.**' id(secaaudt secdaudt audtaudt) acc(r)
