Device Protection

Mobile devices are very easy to lose or steal, so we must have some way of finding those devices; we are going to look at the differences between geofencing, geolocation and using cable locks:

  • Geofencing: Geofencing uses the Global Positioning System (GPS) or RFID to define geographical boundaries; once the device is taken past the defined boundaries, the security team will be alerted.
  • Geolocation: Geolocation uses GPS to give the actual location of a mobile device. This is used when you lose your iPad and then use your iPhone to determine its location. This can be very useful if you lose or drop a device.
  • Cable locks: Cable locks on laptops and tablets prevent them being stolen.
Exam tip:
Geofencing prevents mobile devices from being taken off the company's premises.
