Network Authentication

Since there is no precise bound in

wireless LANs, the WLAN users need

to implement certain mechanism

to provide security solution. The

Authentication policies in this tab

provide protection of different levels

such as Open, WEP, WPA, and WPA2.

Open

- Select this option to make the

network operate on Open System

mode, which use no authentication

algorithm. Open stations and APs can authenticate with each other without

checking any WEP Key, even if there is.

Shared

- Select this option to make the network operate on Shared key mode.

In a Share Key Authentication system, four-step exchange of frames is required

to validate that the station is using the same WEP Key as the access point.

WPA-PSK/ WPA2-PSK

- Select this option to enable WPA Pre-Shared Key

under Infrastructure mode. It enables communication between your client and

APs using WPA-PSK/WPA2-PSK encryption mode.

WPA/ WPA2

- The network is operating in IEEE 802.1x authentication mode.

This mode is for environments with RADIUS (Remote Access Dial-in User

Service). In a RADIUS environment, various Extensible Authentication Protocol

(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, and LEAP.

Cong - Encryption

This page enables you to congure the Wireless LAN Card encryption settings.

For data confidentiality in a wireless environment, IEEE 802.11 specifies a

Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy. The

WEP uses keys to encrypt and decrypt data packets. The encryption process

can scramble frame bits to avoid disclosure to others. The WPA/WPA2 is

improved security system for 802.11 which are developed to overcome the

weakness of the WEP protocol.
