STIGQter: STIG Summary: z/OS ROSCOE for ACF2 Security Technical Implementation Guide Version: 7 Release: 2 Benchmark Date: 01 Oct 2025:

ROSCOE STC datasets are not properly protected.

DISA Rule

SV-224337r1141626_rule

Vulnerability Number

V-224337

Group Title

SRG-OS-000259

Rule Version

ZROSA001

Severity

CAT II

CCI(s)

• CCI-001499 - Limit privileges to change software resident within software libraries.

Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to the ROSCOE started task or batch job datasets is limited to systems programmers and the started task only, and all WRITE and/or greater access is logged.

The ISSO will ensure that all other accesses to the ROSCOE started task or batch job datasets are properly restricted and all required accesses are properly logged.

Datasets to be protected will be:
SYS3.ROSCOE.SYS**
SYS3.ROSCOE.ROSLIB**

Example:

SET RULE
$KEY(SYS3)
ROSCOE.SYS- UID(syspudt) R(A) W(L) A(L) E(A)
ROSCOE.SYS- UID(stc roscoe) R(A) W(L) A(L) E(A)
ROSCOE.ROSLIB- UID(syspudt) R(A) W(L) A(L) E(A)
ROSCOE.ROSLIB- UID(stc roscoe) R(A) W(L) A(L) E(A)

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

- SENSITVE.RPT(ROSSTC).

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

- PDI(ZROS0001).

Verify that access to the ROSCOE STC datasets is properly restricted. The datasets in this group are the datasets identified in the ROSACTxx (if used), ROSLIBxx, and SYSAWSx DD statements of the STC or batch JCL. If the following guidance is true, this is not a finding.

The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to systems programming personnel.

The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to the product STC(s) and/or batch job(s).
