WIRED/WIRELESS PACKET CLASSIFICATION METHOD AND SYSTEM THROUGH A PACKET MARKING AND WIRELESS NETWORK USER INFORMATION EXTRACTION AND TRACE BACK METHOD AND SYSTEM

摘要

A wired/wireless packet classification method and system, and a method and system for extracting and back-tracing wireless network user information by using the same are provided to classify the attack, which causes a security problem, in wired/wireless methods by using IP header marking. A wired/wireless packet classification system through packet marking includes a wired/wireless listener module(240); a packet marking module(250) which does marking at a specific field of a wireless packet transmitted through the wired/wireless listener module; a wired/wireless access point(200) which is configured by including a transmission module(260) re-transmitting a wireless packet through an external connection interface; and a management sever which classifies and stores the wired/wireless packet transferred from the wired/wireless access point.
