802.1X: is an IEEE standard for port-based Network-Access Control, and it provides an
authentication mechanism to devices wishing to attach to a LAN or WLAN. This protocol
restricts unauthorized clients from connecting to a LAN through ports that are open to the
Internet. The authentication basically involves three parties (Fig. 2.49): a supplicant, an
authenticator, and an authentication server.
- Supplicant: The client device that request access to the LAN.
- Authentication Server: The server that performs the actual authentication. We use
RADIUS (Remote Authentication Dial-In User Service) as the authentication server.
