    Abstract: A system and a method for controlling an abnormal traffic based on a fuzzy logic are provided to detect a slow port scan attack and perform a countermeasure using traffic control according to detection information by applying a hierarchical fuzzy logic technique. An intrusion detecting module(200) analyzes a packet received from a network interface through a membership function based on a predetermined time cycle and outputs a fuzzy value representing a port scan attack level. A fuzzy control module(300) recognizes the port scan attack level based on the fuzzy value and outputs a control signal for controlling a traffic according to the port scan attack level. An intrusion blocking module(400) controls the traffic with the network interface by receiving the control signal.
