A Complex Attacks Recognition Method in Wireless Intrusion Detection System

During recent years, the challenge faced by wireless network security is getting severe with the rapid development of internet. However, due to the defects of wireless communication protocol and difference among wired networks, the existing intrusion prevention systems are seldom involved. This paper proposed a method of identifying complicated multistep attacks orienting to wireless intrusion detection system, which includes the submodules of alarm simplification, VTG generator, LAG generator, attack signature database, attack path resolver and complex attack evaluation. By means of introducing logic attack diagram and virtual topological graph, the attach path was excavated. The experimental result showed that this identification method is applicable to the real scene of wireless intrusion detection, which plays certain significance to predict attackers’ ultimate attack intention.
