A large collection of configuration options and initial security de- sign problems have resulted in numerous clever techniques for strengthening WLAN security. These methods range from media access control (MAC) address authentication to the. academic area , Wireless LAN technologies , some risks attacks against wireless technologies , suggesting some recommendations to protect wireless LAN network from attack , Finally we propose some research issues should be focused on in the future. . Keywords: Wireless Networking, Security, 802.11 Standard,. While large corporate LANs are still somewhat viable, they are increasingly being augmented by multiple WLAN segments devised to support unique blends of multi-media and traditional data traffic. Whether these WLAN segments reside in close proximity of one another or in remote locations, each requires unique security. The chapter then examines some basic installation steps. The last major section looks at WLAN security, which is particularly important because the WLAN signals are much more susceptible to being intercepted by an attacker than Ethernet LANs.
