Securing Wi-Fi Networks with Today's Technologies

Over the past few years, the popularity of Wi-Fi networking has grown spectacularly. "Going wireless" is becoming mainstream and the costs of implementing Wi-Fi have dropped dramatically. But just as the popularity of Wi-Fi is growing, so are the well-documented security concerns of
wireless networks. Wi-Fi's native security mechanism, WEP, while still useful for home networking and other light security needs, was proven insufficient for enterprise class networking. Some corporate networks have overcome the problems posed by WEP by deploying complementary technologies to strengthen Wi-Fi's native security to a level suitable for enterprise class protection.

This paper will provide a background and history of Wi-Fi and its security evolution. It will explore the means of securing Wi-Fi with complementary technologies such as Virtual Private Networking (VPN), 802.1X, the Extensible Authentication Protocol (EAP) and RADIUS. In addition, the
paper will offer a glimpse into the future of native Wi-Fi security, Wi-Fi Protected Access (WPA) and 802.11i.
