2.12 Port Security

2.12.1 Static Port Security

Fig. 2.48

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.
