What is Mobile Device Management?
Mobile device management (MDM) is a security software used to monitor, manage and secure mobile devices.
MDM providers use a standard set of Apple protocols to communicate with devices, which means that while the interfaces vary between providers, most of the time the functionality that they provide is very similar. These Apple protocols allow the MDM provider to access specific information about the device and enable functionality that is not available to iOS apps without the help of MDM.
MDM can be used to remotely install, update and manage apps, to update the iOS operating system, to lock the device into Single App Mode, to remotely restart the device in case of problems, to set certain types of restrictions on device use, to configure specific device-level settings (like WiFi network), and to wipe the device if it is lost or stolen. Some of this functionality requires that the device be supervised.
