A Security Overview
More and more people are concerned about protecting your local network from the Internet. The
802.11a/g Router provides several ways to keep your network secure:
Devices on your wired or wireless network are assigned private IP addresses; therefore remote
users from the Internet cannot see nor access them. This provide a firewall between your local
LAN and the Internet.
The 802.11a/g Router implements IP packet filtering with SPI (Stateful Packet Inspection)
capabilities, which you can use to selectively filter (discard) packets to/from the Internet.
You can selectively restrict management to remote devices.
To address the growing security concern in a wireless LAN environment, different levels of security
can also be enabled in the 802.11a/g Router, including:
To disable SSID broadcast so to restrict association to only client stations that are already pre-
configured with the correct SSID.
To enable WEP (Wireless Encryption Protocol) encryption to implement privacy of your data
Support of Access Control List to allow you to grant/deny access to/from specified wireless
stations (using MAC addresses)
Provisioning of centralized authentication through 802.1x and RADIUS Server(s).
To enable WPA (WiFi Protected Access) to assure authorized access as well as to implement
privacy of your data. WPA comes with two modes: 802.1x for enterprise users and PSK (Pre-
Shared Key) for SOHO users.
