DFMSM resource class(es) is(are) not defined to the GSO SAFDEF record in accordance with security requirements (Cat II impact)

Discussion

DFSMS provides data, storage, program, and device management functions for the operating system. Some DFSMS storage administration functions allow a user to obtain a privileged status and effectively bypass all ACP data set and volume controls. Failure to properly protect DFSMS resources may result in unauthorized access. This exposure could compromise the availability and integrity of the operating system environment, system services, and customer data.
