Fix Recommendation

The systems programmer will work with the ISSO to verify that the following are properly specified in the Access Control Program (ACP).

The RACF rules for the CBD resource specify a default access of NONE.
There are no RACF rules that allow access to the CBD resource.

Example:

rdef facility cbd.** uacc(none) owner(admin) audit(failure(read)) -
data('added per PDI ZHCD0020')

The RACF rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming and operations personnel as well as possibly any automated operations batch users with access of READ.
The RACF rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming with access of UPDATE and logged.
All RACF rules are defined with UACC(NONE).

Example:

rdef facility cbd.cpc.iocds.** uacc(none) owner(admin) -
audit(success(update) failures(read)) -
data('added per PDI ZHCD0020')
rdef facility cbd.cpc.iplparm.** uacc(none) owner(admin) -
audit(success(update) failures(read)) -
data('added per PDI ZHCD0020')
