Fix Recommendation

The ISSO will ensure WRITE and/or greater access to CA MICS Resource Management installation datasets is limited to systems programmers and MICS administrators. READ access can be given to all authorized users (e.g., auditors, security administrators, and MICS end 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 Access Control Program (ACP) 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.MICS

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

$KEY(SYS2)
MICS.- UID(syspaudt) R(A) W(L) A(L) E(A)
MICS.- UID(tstcaudt) R(A) W(L) A(L) E(A)
MICS.- UID(micsadm) R(A) W(L) A(L) E(A)
MICS.- UID(audtaudt) R(A) E(A)
MICS.- UID(micsuser) R(A) E(A)
MICS.- UID(secaaudt) R(A) E(A)

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

- SENSITVE.RPT(MICSRPT).

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

- PDI(ZMIC0000).

Verify that the accesses to the CA MICS Resource Management 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 all authorized users (e.g., auditors, security administrators, and MICS end users).

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

The ACF2 dataset access authorizations restrict WRITE and/or greater access to MICS administrators.

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