Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to BMC CONTROL-D installation datasets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors, BMC users, security personnel (domain level and decentralized), and BMC STCs and/or batch users. All failures and successful WRITE and/or greater accesses are logged.

The installing systems programmer will identify and document the product datasets, categorize them according to who will have WRITE and/or greater access, and if required, ensure that all WRITE and/or greater access is logged. The installing systems programmer will identify if any additional groups have WRITE and/or greater access for specific datasets, and once documented will work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program) active on the system.

(Note: The datasets and/or dataset prefixes identified below are examples of a possible installation. The actual datasets and/or prefixes are determined when the product is installed on a system through the product's installation guide and can be site specific.)

Datasets to be protected will be:
SYS2.IOA.*.CTDI

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

$KEY(SYS2)
IOA.-.CTDI.- UID(<syspaudt>) R(A) W(L) A(L) E(A)
IOA.-.CTDI.- UID(<audtaudt>) R(A) E(A)
IOA.-.CTDI.- UID(<bmcuser>) R(A) E(A)
IOA.-.CTDI.- UID(<secaaudt>) R(A) E(A)
IOA.-.CTDI.- UID(<secdaudt>) R(A) E(A)
IOA.-.CTDI.- UID(CONTROLD) R(A) E(A)

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

- SENSITVE.RPT(CTDRPT).

Automated Analysis
Refer to the following report produced by the dataset and Resource Data Collection:

- PDI(ZCTD0000).

Verify that the accesses to the BMC CONTROL-D installation datasets are properly restricted. If the following guidance is true, this is not a finding.

The ACF2 dataset access authorizations restrict READ access to auditors, BMC users, security personnel (domain level and decentralized), and BMC STCs and/or batch users.

The ACF2 dataset access authorizations restrict WRITE and/or greater access to systems programming personnel.

The ACF2 dataset access authorizations specify that all (i.e., failures and successes) WRITE and/or greater access is logged.
