Wireless Security Checklist

Chapter 2: Wireless Security Checklist

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 help keep your network secure.

1. Change the default wireless 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 linksys 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.

4. Enable encryption

Encryption protects data transmitted over a wireless network. Wi-Fi Protected Access (WPA/WPA2) and Wired Equivalent 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.

2. 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 admin. Hackers know these defaults and may try to use them to access your wireless device and change your network settings. To help thwart any unauthorized changes, customize the device’s password so it will be hard to guess.

3. Enable MAC address filtering

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.

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.

Wireless > Basic Wireless Settings

The basic settings for wireless networking are set on this screen.

There are two ways to configure the Router’s wireless network(s), manual and Wi-Fi Protected Setup.

Wi-Fi Protected Setup is a feature that makes it easy to set up your wireless network. If you have client devices, such as wireless adapters, that support Wi-Fi Protected Setup, then you can use Wi-Fi Protected Setup.

Wireless SSID Broadcast When wireless clients survey

the local area for wireless networks to associate with, they will detect the SSID broadcast by the Router. To broadcast the Router’s SSID, keep the default, Enabled. If you do not want to broadcast the Router’s SSID, then select Disabled.

Click Save Settings to apply your changes, or click Cancel Changes to clear your changes.

Wi-Fi Protected Setup

There are three methods available. Use the method that applies to the client device you are configuring.

Wireless > Basic Wireless Settings (Manual Setup)

Wireless Configuration To manually configure your

wireless network, select Manual. Proceed to the “Wireless Network (Manual)” section. To use Wi-Fi Protected Setup, select Wi-Fi Protected Setup. Proceed to Wi-Fi Protected Setup, page 10.

Wireless Network (Manual)

Wireless Network Mode From this drop-down menu,

you can select the wireless standards running on your network. If you have Wireless-N, Wireless-G, and Wireless-B devices in your network, keep the default setting, Mixed. If you have only Wireless-G and Wireless-B devices in your network, select BG-Mixed. If you have only Wireless-N devices, select Wireless-N Only. If you have only Wireless-G devices, select Wireless-G Only. If you have only Wireless-B devices, select Wireless-B Only. If your network has no wireless devices, or if you want to disable wireless networking, select Disabled.

Wireless Network Name (SSID) The SSID is the network

name shared among all points in a wireless network. The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 keyboard characters. For added security, you should change the default SSID (linksys) to a unique name.

Wireless Channel Select the channel from the list

provided to correspond with your network settings. All devices in your wireless network must be broadcast on the same channel in order to function correctly.

Method #1

Use this method if your client device has a Wi-Fi Protected Setup button.

Click or press the1. Wi-Fi Protected Setup button on the client device.

Click the 2. Wi-Fi Protected Setup button on this screen.

After the client device has been configured, click 3. OK. Then refer back to your client device or its documentation for further instructions.

Method #2

Use this method if your client device has a Wi-Fi Protected Setup PIN number.

Enter the PIN number in the1. field on this screen. Click 2. Register. After the client device has been configured, click 3.

OK. Then refer back to your client device or its documentation for further instructions.

Method #3

Wireless Security

Wireless security is strongly recommended, and WPA2 is the strongest method available. Use WPA2 if it is supported by all of your wireless devices.

Security Mode

Select the security method for your wireless network. If you do not want to use wireless security, keep the default, Disabled.

WPA2 Personal

NOTE: If you are using WPA2 or WPA, each

device in your wireless network MUST use the same WPA method and shared key, or else the network will not function properly.

Use this method if your client device asks for the Router’s PIN number.

Enter the PIN number listed on this screen. (It is also 1. listed on the label on the bottom of the Router.)

After the client device has been configured, click 2. OK. Then refer back to your client device or its documentation for further instructions.

The Wi-Fi Protected Setup Status, Network Name (SSID), Security, Encryption, and Passphrase are displayed at the bottom of the screen.

NOTE: If you have client devices that do not

support Wi-Fi Protected Setup, note the wireless settings, and then manually configure those client devices.

Wireless > Wireless Security

The Wireless Security settings configure the security of your wireless network. There are six wireless security mode options supported by the Router: WPA2 Personal, WPA Personal, WPA2 Enterprise, WPA Enterprise, RADIUS, and WEP. WPA (Wi-Fi Protected Access) is a stronger security standard than WEP (Wireless Equivalent Privacy), and WPA2 is even more secure than WPA. RADIUS is Remote Authentication Dial-In User Service. These six are briefly discussed here. For more information about wireless security, refer to Chapter 2: Wireless Security Checklist, page 3.

Security Mode > WPA2 Personal
