Abstract
A device identification method where a device application usage profile is generated and maintained for each one or more known computing devices of a local network based on network traffic data. In response to detecting an unknown computing device in the local network, network traffic data related to the unknown computing device is collected, and a device application usage profile for the unknown computing device is generated based on the network traffic data related to the unknown computing device. The device application usage profile of the unknown computing device is compared with the device application usage profile of the one or more known computing devices of the local network. In response to detecting a difference between the device application usage profile of the unknown computing device and the device application usage profile of the one or more known computing devices of the local network satisfying a predetermined threshold, the unknown device is identified as one of the known computing devices of the local network.
