Method and system for detecting and responding to harmful traffic

Abstract

There is provided a method and system for detecting and responding to harmful traffic. The system includes a router determining whether or not received data is harmful traffic, by using a dynamic flow identification (DFI) function and a deep packet inspection (DPI) function, sending Cflowd information of the received data, and then encapsulating the received data when the received data is determined to be harmful traffic, a policy & resource control entity receiving the Cflowd information from the router, determining whether or not the received data is harmful traffic by using the received Cflowd information, and then sending a result of the determination to the router, and a security management server receiving the encapsulated data from the router, reconfirming whether or not the encapsulated data is harmful traffic, and then processing the encapsulated data.
