SYSTEM AND METHOD FOR DETECTING/RESPONDING TO HARMFUL TRAFFIC THROUGH LINKAGE AMONG MULTIPLE HETEROGENEOUS HARMFUL TRAFFIC DETECTING/RESPONDING DEVICES

摘要

PURPOSE: A system and a method for detecting/responding to a harmful traffic through linkage among multiple heterogeneous harmful traffic detecting/responding devices are provided to protect network by distributing a security policy to the harmful traffic detecting/responding devices with use of a programmable packet and detecting/responding to the harmful traffic through the linkage of the devices. CONSTITUTION: A programmable policy manager generates the security policy applied to the harmful traffic detecting/responding devices(14,22,24,32) by initial input of a user, stores the security policy to a policy repository, and reads/converts a profile of the harmful traffic detecting/responding device into the programmable security policy executable on each harmful traffic detecting/responding device. A programmable policy processor fills a payload part of an IP(Internet Protocol) packet with the programmable security policy. A programmable policy certifier attaches a certification header to the IP packet and encrypts the IP packet. A programmable packet manager converts the completed IP packet into the programmable packet and transfers the programmable packet to the harmful traffic detecting/responding device.
