Description
CA 1 Tape Management 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 ACF2 Data Collection and dataset and Resource Data Collection: - SENSITVE.RPT(CA1STC). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZCA10001). Verify that the accesses to CA1 Tape Management Started Tasks (STCs) 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. 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 CA1 Tape Management STCs and/or batch users.

✔️ Fix
Ensure that WRITE and/or greater access to CA1 Tape management STC datasets is limited to systems programmers and/or CA1 Tape management STC(s) and/or batch user(s) only. (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: CA1.TMS* (Datasets that are altered by the product's STCs can be more specific.) The following commands are provided as a sample for implementing dataset controls: $KEY(SYS3) CA1.TMS.- UID(<syspaudt>) R(A) W(A) A(A) E(A) CA1.TMS.*- UID(<Tape Management STCs and/or batch users >) R(A) W(A) A(A) E(A) CA1.TMS.**- UID(<audtaudt>) R(A) E(A)
