Security in an insecure WLAN network

Wireless LANs (WLANs) based on IEEE 802.11 standards are becoming increasingly popular for both business and residential use. However, the very nature of wireless networks exposes the risks and vulnerabilities that a malicious user can exploit and severely compromise the network. In this paper, we provide a design of a secure wireless system (SWS) that can not only detect various attacks and misbehaviors of a 802.11 based wireless networks, but also help recover from them. A prototype implementation is also described.
