IEEE 802.1x

IEEE 802.1x overview

The IEEE 802.1x standard outlines enhanced security methods for both the
authentication of users and encryption key management. Authentication can be
done using the local user database internal to the Business Secure Router
(authenticate up to 32 users) or an external RADIUS server for an unlimited
number of users.

RADIUS

RADIUS is based on a client-sever model that supports authentication and
accounting, where users are the clients and the server is the RADIUS server. The
RADIUS server handles the following tasks, among others:
•
•
RADIUS is a simple package exchange in which your Business Secure Router
acts as a message relay between the user and the network RADIUS server.

Types of RADIUS messages

The following types of RADIUS messages are exchanged between the Business
Secure Router and the RADIUS server for user authentication:
Authentication
Determines the identity of the users.
Accounting
Keeps track of the client's network activity.
