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.
