Description
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.
