IEEE 802.1X is a port-based security standard (set by the IEEE 802.1 Working Group) for network access control. IEEE 802.1X for IEEE 802.11 takes advantage of standard protocols such as EAP and RADIUS to provide centralized user identification, authentication, dynamic key management,and accounting.
This protocol is compatible with wireless roaming technologies, working between supplicants and authenticators. Authentication and authorization are achieved with back-end communications to an authentication server, such as Cisco Secure Access Control Server (ACS).
