Configure ESM data set rules to ensure that all WRITE and/or greater access to all PROCLIBs referenced in the Master JCL and JES2 or JES3 procedure for started tasks (STCs) and TSO logons are restricted to systems programming personnel only. Suggestion on how to update system to be compliant with this vulnerability: NOTE: All examples are only examples and may not reflect your operating environment. Obtain only the PROCLIB data sets that contain STC and TSO procedures. The data sets to be reviewed are obtained using the following steps: - All data sets contained in the MSTJCLxx member in the DD statement concatenation for IEFPDSI and IEFJOBS. - The data set in the PROCxx DD statement concatenation that are within the JES2 procedure or identified in the JES2 dynamic PROCLIB definitions....
