Fix Recommendation

The IAO will ensure that The IAO will ensure that WRITE and/or greater access to Transparent Data Migration Facility (TDMF) installation data sets is limited to System Programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors.

The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have WRITE and/or greater access and if required that all WRITE and/or greater access is logged. He will identify if any additional groups have WRITE and/or greater 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.TDMF.
SYS3.TDMF.

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

$KEY(SYS2)
TDMF.- UID(<syspaudt>) R(A) W(L) A(L) E(A)
TDMF.- UID(<tstcaudt>) R(A) W(L) A(L) E(A)
TDMF.- UID(<audtaudt>) R(A) E(A)

$KEY(SYS3)
TDMF.- UID(<syspaudt>) R(A) W(L) A(L) E(A)
TDMF.- UID(<tstcaudt>) R(A) W(L) A(L) E(A)
TDMF.- UID(<audtaudt>) R(A) E(A)

Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZTDM0000)

Verify that the accesses to the Transparent Data Migration Facility (TDMF) installation data sets are properly restricted. If the following guidance is true, this is not a finding.

___ The ACF2 data set rules for the data sets restricts READ access to auditors.

___ The ACF2 data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel.

___ The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.
