Abstract
A system and method for intercepting intra-network traffic for smart appliance behavior analysis. A network traffic hub is configured to intercept network traffic between a switch and a router. A smart appliance sends a message to the router, such as a DHCP request when the smart appliance joins the network. The router sends a response to the smart appliance. The network traffic hub intercepts and modifies the response to instruct the smart appliance to send all future intra-network traffic through the network traffic hub and the router. In some embodiments, the network traffic hub alters a network mask in the response message to instruct the smart appliance to send traffic through the network traffic hub. The network traffic hub then extracts data from the network traffic and uses that data for behavior analysis of smart appliances.
