Abstract

The increasing reliance upon wireless networks has put tremendous emphasis on wireless network security. Intrusion detection in wireless network has become an indispensable component of any useful wireless network security system, and has recently gained attention in both research and industry communities due to widespread use of wireless local area network (WLAN). Although some intrusion prevention systems have recently appeared in the market, their intrusion detection capabilities are limited. This paper focus on detecting intrusion or anomalous behavior of nodes in WLAN’s using modular technique. We explore the security vulnerabilities of 802.11, numerous intrusion detection techniques, and different network traffic metrics also called as features. Based on the study of metrics we propose a modular based intrusion detection approach.
