SYSTEM AND METHOD FOR RESPONDING DDoS OFFENSIVE

摘要

PURPOSE: A system and method of DDoS(Distributed Denial-of-Service) attack are provided to monitor the amount of traffic of a web server in a detector and to block the DDoS attack through a blocking device. CONSTITUTION: A detector(20) transmits a packet in a web server. The detector detects DDoS attack about the web server. If the DDoS attack is detected, a router(30) constitutes a provisional transmission path about the packet demanded for the transmission of the web server. A blocker receives the packet which is requested to the web sever along a transmission path. The blocker determines whether the received packet is transmitted to the web server.
