74 Chapter 6 Wireless Screens

The figure below shows the possible wireless security levels on your G-570S. EAP

(Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key

exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User

Service) server either on the WAN or your LAN to provide authentication service for wireless

stations.

If you do not enable any wireless security on your G-570S, your network is accessible to any

wireless networking device that is within range.

6.4.1 Encryption

• Use WPA(2) security if you have WP(2)A-aware wireless clients and a RADIUS server.

WPA(2) has user authentication and improved data encryption over WEP.

• Use WPA(2)-PSK if you have WPA(2)-aware wireless clients but no RADIUS server.

• If you don’t have WPA(2)-aware wireless clients, then use WEP key encrypting. A

higher bit key offers better security at a throughput trade-off. You can use the passphrase

feature to automatically generate WEP keys or manually enter WEP keys.

6.4.2 Authentication

Use a RADIUS server with WPA or IEEE 802.1x key management protocol.

See the appendix for information on protocols used when a client authenticates with a

RADIUS server via the G-570S.

6.4.3 Restricted Access

The MAC Filter screen allows you to configure the AP to give exclusive access to devices

(Allow Association) or exclude them from accessing the AP (Deny Association).
