Chapter2Wireless Security Checklist 3 W reless-G Broadband Router Chapter : W reless Securty Checklst Wireless networks are convenient and easy to install, so homes with high-speed Internet access are adopting them at a rapid pace . Because wireless networking operates by sending information over radio waves, it can be more vulnerable to intruders than a traditional wired network . Like signals from your cellular or cordless phones, signals from your wireless network can also be intercepted . Since you cannot physically prevent someone from connecting to your wireless network, you need to take some additional steps to keep your network secure . . Change the default wreless network name or SSID Wireless devices have a default wireless network name or Service Set Identifier (SSID) set by the factory . This is the name of your wireless network, and can be up to 32 characters in length . Linksys wireless products use lnksys as the default wireless network name . You should change the wireless network name to something unique to distinguish your wireless network from other wireless networks that may exist around you, but do not use personal information (such as your Social Security number) because this information may be available for anyone to see when browsing for wireless networks . . Change the default password For wireless products such as access points and routers, you will be asked for a password when you want to change their settings . These devices have a default password set by the factory . The Linksys default password is admn . Hackers know these defaults and may try to use them to access your wireless device and change your network settings . To thwart any unauthorized changes, customize the device’s password so it will be hard to guess . 3. Enable MAC address flterng Linksys routers give you the ability to enable Media Access Control (MAC) address filtering . The MAC address is a unique series of numbers and letters assigned to every networking device . With MAC address filtering enabled, wireless network access is provided solely for wireless devices with specific MAC addresses . For example, you can specify the MAC address of each computer in your home so that only those computers can access your wireless network . 4. Enable encrypton Encryption protects data transmitted over a wireless network . Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalency Privacy (WEP) offer different levels of security for wireless communication . Currently, devices that are Wi-Fi certified are required to support WPA2, but are not required to support WEP . A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP, because WPA/WPA2 uses dynamic key encryption . To protect the information as it passes over the airwaves, you should enable the highest level of encryption supported by your network equipment . WEP is an older encryption standard and may be the only option available on some older devices that do not support WPA . General Network Security Guidelines Wireless network security is useless if the underlying network is not secure . Password protect all computers on the network and individually password protect sensitive files . Change passwords on a regular basis . Install anti-virus software and personal firewall software . Disable file sharing (peer-to-peer) . Some applications may open file sharing without your consent and/or knowledge . Additional Security Tips Keep wireless routers, access points, or gateways away from exterior walls and windows . Turn wireless routers, access points, or gateways off when they are not being used (at night, during vacations) . Use strong passphrases that are at least eight characters in length . Combine letters and numbers to avoid using standard words that can be found in the dictionary . WEB: For more information on wireless security, visit www.lnksys.com/securty • • • • • • •

Chapter3Advanced Configuration W reless-G Broadband Router Network Setup The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports . Wireless Setup is performed through the Wireless tab . Router IP This presents both the Router’s IP Address and Subnet Mask as seen by your network . Router IP Address Network Address Server Settings (DHCP) The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function . The Router can be used as a DHCP server for your network . A DHCP server automatically assigns an IP address to each computer on your network . If you choose to enable the Router’s DHCP server option, make sure there is no other DHCP server on your network . Network Address Server Settings (DHCP) DHCP Server DHCP is enabled by factory default . If you already have a DHCP server on your network, or you don’t want a DHCP server, then select Dsable (no other DHCP features will be available) . Startng IP Address Enter a value for the DHCP server to start with when issuing IP addresses . Because the Router’s default IP address is 192 .168 .1 .1, the Starting IP Address must be 192 .168 .1 .2 or greater, but smaller than 192 .168 .1 .253 . The default Starting IP Address is 9.68..00 .
