碩士 === 大同大學 === 通訊工程研究所碩士在職專班 === 91 === The topic of this thesis is the Wireless LAN 802.11b network security. We discuss the WLAN security mechanisms including the comparisons of SSIDs, MAC address filtering and the WEP key encryption. Based on these authentication methods, we list some hacker’s tricks that include SSID enumeration, MAC address spoofing and WEP key cracking by FMS Attack [2]. This thesis also verified these mechanisms by experiments. Some of these results just fit what the theory describes. Some of these attacks are not as easy as the press said. With the rapid developments of WLAN and the large demands of wireless equipments, the vendors propose many solutions. This thesis also introduces how these companies do their security enhancement research. And they make WLAN managements concerned with humanities to save more MIS agents’ working time. It makes more convenient of wireless equipment maintenance. Finally, we proposed what could be probed for further on.
