SYSTEM AND METHOD FOR PREVENTING BYPASS OF FIREWALL CENSORSHIP ON NETWORK

摘要

PURPOSE: A system and a method for preventing a bypass of the firewall censorship on the network are provided to safely secure an internal network from the censorship bypass hacking by equipping with an intrusion blocking system to check an internal network user using a peekabooty program and block the user from the connection to a web site. CONSTITUTION: A hacking information providing system(30) provides a list file of a network IP(Internet Protocol) address registered to a firewall censorship bypass program that intrudes into the system on the network by bypassing the firewall censorship for a set network security policy. A plurality of client systems(10) connects to the web site servers providing a web service on the network. An intrusion blocking system(40) updates the network security policy with a filtered IP by filtering the IP address of the client system connected to the internal network with a network IP address list file provided from the hacking information providing server. The intrusion blocking system blocks or approves the connection of the client systems and the web site server by using the updated policy.
