ROSCOE STC data sets are not properly protected.

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.

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 are 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 TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel.

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

The ISSO will ensure that WRITE and/or greater/create access to the ROSCOE started task or batch job data sets is limited to systems programmers and the started task only and all WRITE and/or greater/create 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.ROSLIB**

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