CISSP Fix

The IEEE 802.1X standard defines a method of authenticating and authorizing users to connect to an IEEE 802 LAN. It blocks users from accessing the network on the failure of authentication. IEEE 802.1X supports the Extensible Authentication Protocol-Transport Level Security (EAP-TLS) and Protected EAP-Microsoft Challenge Handshake Authentication Protocol version 2 (PEAP-MS-CHAP v2) protocols. In the IEEE802.1X authentication system, an access point receives a connection request from a wireless client and forwards the request to the RADIUS server. The RADIUS server then uses the Active Directory database to determine whether the client should be granted access to the network.
