A method of operating a terminal using Mobile Device Management (MDM) solution includes: installing an application, requesting for registration by a license key received from an Enterprise License Management (ELM) server, receiving a Right Object (R/O) that corresponds to the license key and comprises a permission list, setting at least one permission based on the permission list comprised in the received R/O, and performing the set permission. A terminal using MDM comprises an MDM application configured to control an installed application to acquire a required permission, a ELM agent configured to request for registration by a license key from an ELM server, and receive a R/O that corresponds to the license key and comprises a permission list, and an ELM permission enforcer configured to set at least one permission based on the permission list comprised in the received R/O.
