A WEB PROTECTION SYSTEM USING AN URI CONTENT IDENTIFICATION AND THE METHOD THEREOF

摘要

PURPOSE: A web load attack blocking device using URI contents discrimination and an attack blocking method are provided to discriminate a malicious user with the use of the same URI contents in a short time. CONSTITUTION: A packet parser module(10) extracts the information of a client from a inflow payload packet. A hash generation module(20) applies a hash function to the extracted information of the packet parser module. A DDoS(Distributed Denial of Service) detection and protection module(30) receive the hash values of the hash generation module and the extracted information. The DDoS detection and protection module detects the load attack of a web server. In case of the message of a malicious user, the DDoS detection and protection module secludes a packet.
