Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless
clients, access points and the wired network.
Wireless security methods available on the ZyXEL Device are data encryption, wireless client
authentication, restricting access by device MAC address and hiding the ZyXEL Device
identity.
The following figure shows the relative effectiveness of these wireless security methods
available on your ZyXEL Device.
Note: You must enable the same wireless security settings on the ZyXEL Device and
on all wireless clients that you want to associate with it.
RADIUS
RADIUS is based on a client-server model that supports authentication, authorization and
accounting. The access point is the client and the server is the RADIUS server. The RADIUS
server handles the following tasks:
• Authentication
Determines the identity of the users.
• Authorization
Determines the network services available to authenticated users once they are connected
to the network.
• Accounting
Keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your AP acts as a message relay between the
wireless client and the network RADIUS server.
