Chapter 2 Wireless Security Checklist


Chapter 2:Wireless Security ChecklistWireless networks are convenient and easy to install, sohomes with high-speed Internet access are adopting them

at a rapid pace. Because wireless networking operates bysending inormation over radio waves, it can be morevulnerable to intruders than a traditional wired network.Like signals rom your cellular or cordless phones, signalsrom your wireless network can also be intercepted. Sinceyou cannot physically prevent someone rom connectingto your wireless network, you need to take some additionalsteps to keep your network secure.

1. Change the default wirelessnetwork name or SSID

Wireless devices have a deault wireless network nameor Service Set Identiier (SSID) set by the actory. Thisis the name o your wireless network, and can be upto 32 characters in length. Linksys wireless productsuse linksys as the deault wireless network name. Youshould change the wireless network name to somethingunique to distinguish your wireless network rom otherwireless networks that may exist around you, but do notuse personal inormation (such as your Social Securitynumber) because this inormation may be available oranyone to see when browsing or wireless networks.

2. Change the default password

For wireless products such as access points and routers,you will be asked or a password when you want to changetheir settings. These devices have a deault password setby the actory. The Linksys deault password is admin.Hackers know these deaults and may try to use themto access your wireless device and change your networksettings. To thwart any unauthorized changes, customizethe devices password so it will be hard to guess.

3. Enable MAC address filteringLinksys routers give you the ability to enable Media AccessControl (MAC) address iltering. The MAC address is aunique series o numbers and letters assigned to everynetworking device. With MAC address iltering enabled,wireless network access is provided solely or wirelessdevices with speciic MAC addresses. For example, you canspeciy the MAC address o each computer in your homeso that only those computers can access your wirelessnetwork.

4. Enable encryption

Encryption protects data transmitted over a wirelessnetwork. Wi-Fi Protected Access (WPA/WPA2) and WiredEquivalent Privacy (WEP) oer dierent levels o security

or 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 inormationas it passes over the airwaves, you should enable thehighest level o 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 i the underlyingnetwork is not secure.

Password protect all computers on the network andindividually password protect sensitive iles.

Change passwords on a regular basis.

Install anti-virus sotware and personal irewallsotware.

Disable ile sharing (peer-to-peer). Some applicationsmay open ile sharing without your consent and/or

knowledge.

Additional Security Tips

Keep wireless routers, access points, or gateways awayrom exterior walls and windows.

Turn wireless routers, access points, or gatewayso 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 ound in the dictionary.
