Fix Recommendation

The IAO will ensure that update and alter access to BMC MAINVIEW for z/OS installation data sets is limited to System Programmers only, and all update and alter 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 update and alter access and if required that all update and alter access is logged. He will identify if any additional groups have update and/or alter 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:
SYS2.BMCVIEW.**
SYS3.BMCVIEW.** (data sets that are not altered by product STCs, can be more specific)

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

ad 'SYS2.BMCVIEW.**' uacc(none) owner(sys2) -
audit(success(update) failures(read)) -
data('BMC MAINVIEW for z/OS Install DS')
pe 'SYS2.BMCVIEW.**' id(<syspaudt> <tstcaudt>) acc(a)
pe 'SYS2.BMCVIEW.**' id(<audtaudt> authorized users) acc(r)
pe 'SYS2.BMCVIEW.**' id(MAINVIEW STCs)

ad 'SYS3.BMCVIEW.**' uacc(none) owner(sys3) -
audit(success(update) failures(read)) -
data('BMC MAINVIEW for z/OS Install DS')
pe 'SYS3.BMCVIEW.**' id(<syspaudt> <tstcaudt>) acc(a)
pe 'SYS3.BMCVIEW.**' id(<audtaudt> authorized users) acc(r)
pe 'SYS3.BMCVIEW.**' id(MAINVIEW STCs)
