Abstract
A system for controlling abnormal traffic based on a fuzzy logic includes: an intrusion detection module for analyzing packets incoming from a network interface by means of a membership function defined based on a specific period of time, and outputting a fuzzy value representing a degree of a port scan attack; a fuzzy control module for recognizing the degree of the port scan attack based on the fuzzy value and outputting a control signal for traffic control according to the recognized degree of the port scan attack; and an intrusion blocking module for receiving the control signal and controlling the traffic with the network interface.
