Security Enhancement in WLANs Utilizing 802.1x

By | January 10, 2005

Security enhancements for wireless LANs are available through the IEEE 802.1x standard and through dynamic key encryption (WPA) based on the widely accepted Temporal Key Integrity Protocol (TKIP). 802.1x requires users to authenticate with an authentication and authorization server (RADIUS, LDAP, or Active Directory).

However, while 802.1x can prevent unauthorized users from associating to a WLAN, limitations of the standard prevent 802.1x from being effective in all environments.

For example, because the 802.1x standard requires client hardware and configuration, WLAN deployments integrating 802.1x must be homogeneous in terms of user groups and participating wireless clients.
