ROSCOE STC data sets are not properly protected.

Rule version ZROSR001 · STIG v7 · 2025-09-27

Discussion

ROSCOE STC data sets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.

Check

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

- SENSITVE.RPT(ROSSTC).

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

- PDI(ZROS0001).

Verify that access to the ROSCOE STC data sets is properly restricted. The data sets in this group are the data sets 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 RACF data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel.

The RACF data set rules for the data sets restrict WRITE and/or greater access to the product STC(s) and/or batch job(s).

Fix

The ISSO will ensure that WRITE and/or greater access to the ROSCOE started task or batch job data sets is limited to system 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 data sets are properly restricted and all required accesses are properly logged.

Data sets to be protected will be:

SYS3.ROSCOE.sys*.** SYS3.ROSCOE.ros*.**

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

ad 'sys3.roscoe.ros*.**' uacc(none) owner(sys3) - audit(success(update) failures(read)) - data('Site Customized Profile: ROSCOE') pe 'sys3.roscoe.ros*.**' id(syspaudt) acc(a) pe 'sys3.roscoe.ros*.**' id(roscoe) acc(a) ad 'sys3.roscoe.sys*.**' uacc(none) owner(sys3) - audit(success(update) failures(read)) - data('Site Customized profile: ROSCOE') pe 'sys3.roscoe.sys*.**' id(syspaudt) acc(a) pe 'sys3.roscoe.sys*.**' id(roscoe) acc(a) setr generic(dataset) refresh
