The wireless LAN standard IEEE 802.11b provides a mechanism for authentication and encryption. This paper describes the security of Wireless Local Area Networks based on the IEEE 802.11 standard. Such networks are also known as Wi-Fi Networks or WLANs. We have analyzed different tools that used, to attack a wireless network. We have successfully detect different types of attack and found some flaws in WLAN. We conclude this research with several recommendations that will help improve security at a wireless deployment site.30 pagesBRAC University thesis are protected by copyright.
