Chapter 1 Getting to Know Your G-570U 25

IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE

802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa)

at 11 Mbps or lower depending on range.

Wi-Fi Protected Access

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key differences

between WPA and WEP are user authentication and improved data encryption.

WPA2

WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption,

authentication and key management than WPA.

SSL Passthrough

The G-570U allows SSL connections to go through the G-570U. SSL (Secure Sockets Layer)

uses a public key to encrypt data that's transmitted over an SSL connection. Both Netscape

Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain

confidential user information, such as credit card numbers. By convention, URLs that require

an SSL connection start with "https" instead of "http".

Wireless LAN MAC Address Filtering

Your G-570U checks the MAC address of the wireless station against a list of allowed or

denied MAC addresses.

WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless

network to help keep network communications private.

IEEE 802.1x Network Security

The G-570U supports the IEEE 802.1x standard to enhance user authentication. Use an EAP-

compatible RADIUS (RFC2138, 2139 - Remote Authentication Dial In User Service) server

to authenticate a limitless number of users using EAP (Extensible Authentication Protocol).

EAP is an authentication protocol that supports multiple types of authentication.

Full Network Management

The embedded web configurator is an all-platform web-based utility that allows you to easily

access the G-570U's management settings.

Logging and Tracing

Built-in message logging and packet tracing.
