Fix Recommendation

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

1) The TSS owner is defined for the CBD resources and/or IBMFAC RDT entry has DEFPROT specified.

For Example:

TSS ADD(dept-acid)IBMFAC(CBD.)

TSS REP(RDT)RESCLASS(IBMFAC)ATTR(DEFPROT)

2) There are no TSS rules that allow access to the CBD resource.

3) 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.
4) 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.

Example:

TSS PERMIT(syspaudt)IBMFAC(CBD.CPC.IOCDS)ACCESS(READ)
TSS PERMIT(operaudt)IBMFAC(CBD.CPC.IOCDS)ACCESS(READ)
TSS PERMIT(autoaudt)IBMFAC(CBD.CPC.IOCDS)ACCESS(READ)
TSS PERMIT(syspaudt)IBMFAC(CBD.CPC.IOCDS) –
ACCESS(UPDATE)ACTION(AUDIT)
TSS PERMIT(syspaudt)IBMFAC(CBD.CPC.IPLPARM)ACCESS(READ)
TSS PERMIT(operaudt)IBMFAC(CBD.CPC.IPLPARM)ACCESS(READ)
TSS PERMIT(autoaudt)IBMFAC(CBD.CPC.IPLPARM)ACCESS(READ)
TSS PERMIT(syspaudt)IBMFAC(CBD.CPC.IPLPARM) –
ACCESS(UPDATE)ACTION(AUDIT)

b) Review the following items for the IBM Hardware Configuration Definition (HCD) resources in the IBMFAC resource class:

1) The TSS owner is defined for the CBD resource and/or IBMFAC RDT entry has DEFPROT specified.
2) There are no TSS rules that allow access to the CBD resource.
3) The TSS 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 TSS rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming with access of UPDATE and logged.

c) If any item in (b) is untrue, this is a FINDING.

d) If all items in (b) are true, this is NOT A FINDING.
