DFSMSdss has no special support for the name-hiding function. Your installation is responsible for protecting DFSMSdss functions and resources from unauthorized users. You can use the existing procedures to limit the use of DFSMSdss function by authorized users. For example, you can prevent disclosing names by placing DFSMSdss in a protected library that only authorized users can use.

For more information about how to protect a library, refer to Protecting DFSMSdss/ISMF modules.
