Wireless Security Implications of 802.11n
I am sure that all of us have bumped into IEEE 802.11n at some point in time – it is the latest sensation in the 802.11 family of standards. It enhances the operative range of Wi-Fi devices and enables wire-speeds. It is no surprise that most (probably all) of the wireless LAN (WLAN) equipment vendors have announced support for 802.11n. Each vendor seems to be claiming that they have the “most conducive” architecture to avail the performance benefits of 802.11n. In this article, as usual, I would like to get your attention to another important aspect of an 802.11n deployment – security. While it doesn’t explicitly introduce new security features, 802.11n does introduce certain unique challenges to your enterprise wireless LAN (WLAN) security. Here’s how:
