Description
BMC CONTROL-D STC datasets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these datasets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.

ℹ️ Check
Refer to the following report produced by the dataset and Resource Data Collection: - SENSITVE.RPT(CTDSTC). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZCTD0001). Verify that the accesses to the BMC CONTROL-D STC 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 and CONTROL-D 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 BMC STCs and/or batch users. The ACF2 dataset access authorizations restrict UPDATE access to centralized and decentralized security personnel.

✔️ Fix
The ISSO will ensure that WRITE and/or greater access to BMC CONTROL-D STC datasets is limited to systems programmers and BMC STCs and/or batch users. UPDATE access can be given to centralized and decentralized security personnel. READ access can be given to auditors and BMC users. 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: SYS3.IOA.*.CTDO The following commands are provided as a sample for implementing dataset controls: $KEY(SYS3) IOA.-.CTDO.- UID(syspaudt) R(A) W(A) A(A) E(A) IOA.-.CTDO.- UID(tstcaudt) R(A) W(A) A(A) E(A) IOA.-.CTDO.- UID(BMC STCs) R(A) W(A) A(A) E(A) IOA.-.CTDO.- UID(secaaudt) R(A) W(A) E(A) IOA.-.CTDO.- UID(secdaudt) R(A) W(A) E(A) IOA.-.CTDO.- UID(audtaudt) R(A) E(A) IOA.-.CTDO.- UID(bmcuser) R(A) E(A)
