IEEE 802.1x offers an effective framework for authenticating and controlling user traffic to a protected network, as well as providing a vehicle for dynamically varying data encryption keys via EAP from a RADIUS server, for example. This framework enables using a central authentication server, which employs mutual authentication so that a rogue wireless user does not join the network.
It is important to note that 802.1x does not provide the actual authentication mechanisms. When using 802.1x, the EAP type, such as Transport Layer Security
Note: For environments with a Remote Authentication
Together, these technologies provide a framework for strong user authentication.
Windows XP implements 802.1x natively, and several NETGEAR switch and wireless access point products support 802.1x.
