3.12.5 Network Access Server (802.1X)
The IEEE 802.1X standard defines a port-based access control procedure that prevents
unauthorized access to a network by requiring users to first submit credentials for authentication.
One or more central servers (the backend servers
)
determine whether the user is allowed access to
the network.
