Wireless Security ChecklistChapter 2Chapter 2:Wireless Security ChecklistWireless networks are convenient and easy to install, sohomes with high-speed Internet access are adopting themat a rapid pace. Because wireless networking operates bysending information over radio waves, it can be morevulnerable to intruders than a traditional wired network.Like signals from your cellular or cordless phones, signalsfrom your wireless network can also be intercepted. Sinceyou cannot physically prevent someone from connectingto your wireless network, you need to take some additionalsteps to keep your network secure.1. Change the default wirelessnetwork name or SSIDWireless devices have a default wireless network nameor Service Set Identifier (SSID) set by the factory. Thisis the name of your wireless network, and can be upto 32 characters in length. Linksys wireless productsuse linksys as the default wireless network name. Youshould change the wireless network name to somethingunique to distinguish your wireless network from otherwireless networks that may exist around you, but do notuse personal information (such as your Social Securitynumber) because this information may be available foranyone to see when browsing for wireless networks.2. Change the default passwordFor wireless products such as access points, routers, andgateways, you will be asked for a password when youwant to change their settings. These devices have a defaultpassword set by the factory. The Linksys default passwordis admin. Hackers know these defaults and may try touse them to access your wireless device and change yournetwork settings. To thwart any unauthorized changes,customize the device’s password so it will be hard toguess.3. Enable MAC address filtering4. Enable encryptionEncryption protects data transmitted over a wirelessnetwork. Wi-Fi Protected Access (WPA/WPA2) and WiredEquivalency Privacy (WEP) offer different levels of securityfor wireless communication.A network encrypted with WPA/WPA2 is more securethan a network encrypted with WEP, because WPA/WPA2uses dynamic key encryption. To protect the informationas it passes over the airwaves, you should enable thehighest level of encryption supported by your networkequipment.WEP is an older encryption standard and may be theonly option available on some older devices that do notsupport WPA.General Network Security GuidelinesWireless network security is useless if the underlyingnetwork is not secure. Password protect all computers on the network andindividually password protect sensitive files. Change passwords on a regular basis. Install anti-virus software and personal firewallsoftware. Disable file sharing (peer-to-peer). Some applicationsmay open file sharing without your consent and/orknowledge.Additional Security Tips Keep wireless routers, access points, or gateways awayfrom exterior walls and windows. Turn wireless routers, access points, or gatewaysoff when they are not being used (at night, duringvacations). Use strong passphrases that are at least eight charactersin length. Combine letters and numbers to avoid usingstandard words that can be found in the dictionary.WEB: For more information on wirelesssecurity, visit www.linksys.com/securityLinksys routers and gateways give you the ability toenable Media Access Control (MAC) address filtering. TheMAC address is a unique series of numbers and lettersassigned to every networking device. With MAC addressfiltering enabled, wireless network access is providedsolely for wireless devices with specific MAC addresses.For example, you can specify the MAC address of eachcomputer in your home so that only those computers canaccess your wireless network.Wireless-G Router for 3G/UMTS Broadband
