Wireless LAN Intrusion Detection Systems: Something's in the "Air"

Published: 10 November 2005

Analyst(s): Diana Kelley


Enterprise wireless local area networks (WLANs) are a reality. Much has been written about the security threats associated with deployment of WLANs. Many organizations mitigate some of these risks using access authentication and encryption technologies such as virtual private networks (VPNs), Wi-Fi Protected Access (WPA), and WPA2 with 802.1x. In addition to these measures, a class of tools is available to help companies manage and monitor security traffic on the WLAN to increase their overall network security stance.
