Abstract
Malicious behavior of a device on a local network may be detected. A data stream from a device may be collected. A functional group may be created using behavioral data of devices of a known type. A behavior profile for the functional group may be generated and stored in a database. The data stream of the device is compared to the behavior profile of the functional group. A malicious behavior is indicated for the device in response to determining that the device's current behavior is not within a predetermined or configurable threshold of the behavior profile.
