Network switches provide easy and open access to resources, by simply attaching a client PC. Unfortunately
this automatic configuration also allows unauthorized personnel to easily intrude and possibly gain access to
sensitive data.
IEEE-802.1X provides a security standard for network access control, especially in Wi-Fi wireless networks.
802.1X holds a network port disconnected until authentication is completed. The switch uses Extensible
Authentication Protocol over LANs (EAPOL) to exchange authentication protocol client identity (such as a
user name) with the client, and forward it to another remote RADIUS authentication server to verify access
rights. The EAP packet from the RADIUS server also contains the authentication method to be used. The
client can reject the authentication method and request another, depending on the configuration of the client
software and the RADIUS server. Depending on the authenticated results, the port is either made available
to the user, or the user is denied access to the network.
The RADIUS servers make the network a lot easier to manage for the administrator by gathering and storing
the user lists.
