Killing Lost or Stolen Portable Computers by Using the Global Positioning System

A major source of security lapses occurs when corporate laptops and smartphones such as a BlackBerry are lost or stolen. Confidential corporate information and private e-mail messages are often stored on these devices. Currently, mobile carriers have the ability to remotely disable mobile handsets, laptops with cellular cards, and tablets
when corporations report them lost.
Global Positioning System (GPS) chips within these devices enable organizations to locate them so that data can be deleted or the device can be locked. For the carrier to locate a device, it must be turned on and within the carrier’s coverage area. Many mobility management platforms have this capability, as well.
Killing and locating lost devices is enabled in 3G networks. These networks depend on GPS to synchronize the timing in their networks so that signals arrive at their destination only once, and for other functions that require precise timing. GPS equipped mobile networks can be used to provide location information, as well. Location-
based applications that use GPS include applications that give parents the ability to track their children’s locations and to find friends who are in the area. 4G networks also have GPS capabilities.
