7.6 802.1x Overview
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations
and encryption key management. Authentication can be done using the local user database internal to the
ZyWALL or an external RADIUS server for an unlimited number of users.
7.6.1 RADIUS

the client and the server is the RADIUS server. The RADIUS server handles the following tasks among
others:
• Authentication
Determines the identity of the users.
• Accounting
Keeps track of the client’s network activity.
