Fix Recommendation

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

The ACF2 rules for the CBD resource specify a default access of NONE.

No ACF2 rules allow access to the CBD resource.

Example:

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

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.

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
