Fix Recommendation

The systems programmer will work with the IAO to verify that the following are properly specified in the ACP.

1) The ACF2 rules for the CBD resource specify a default access of NONE.
2) There are no ACF2 rules that allow access to the CBD resource.

Example:

SET R(FAC)
$KEY(CBD) TYPE(FAC)
- UID(*) PREVENT DATA(SRR FINDING FOR HCD)

3) The ACF2 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.
4) The ACF2 rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming with access of UPDATE and logged.

Example:

SET R(FAC)
$KEY(CBD) TYPE(FAC)
CPC.IOCDS.- UID(syspaudt) SERVICE(READ,UPDATE) LOG
CPC.IOCDS.- UID(operaudt) SERVICE(READ) ALLOW
CPC.IOCDS.- UID(autoaudt) SERVICE(READ) ALLOW
CPC.IPLPARM.- UID(syspaudt) SERVICE(READ,UPDATE) LOG
CPC.IPLPARM.- UID(operaudt) SERVICE(READ) ALLOW
CPC.IPLPARM.- UID(autoaudt) SERVICE(READ) ALLOW
