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 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.

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 thwart any unauthorized changes, customize the device’s password so it will be hard to guess.

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.

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.

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.

NAT

Enabled/Disabled If this Router is hosting your network’s

connection to the Internet, keep the default, Enabled. If another router exists on your network, select Disabled. When the NAT setting is disabled, dynamic routing will be enabled.

Dynamic Routing (RIP)

Enabled/Disabled This feature enables the Router to

automatically adjust to physical changes in the network’s layout and exchange routing tables with the other router(s). The Router determines the network packets’ route based on the fewest number of hops between the source and the destination. When the NAT setting is enabled, the Dynamic Routing feature is automatically disabled. When the NAT setting is disabled, this feature is available. Select Enabled to use the Dynamic Routing feature.

Static Routing

A static route is a pre-determined pathway that network information must travel to reach a specific host or network. Enter the information described below to set up a new static route.

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

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 characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your wireless network. For added security, you should change the default SSID (linksys) to a unique name.

Channel Width For best performance in a Wireless-N

network, select 40MHz only. For Wireless-G and Wireless-B networking only, keep the default, 20MHz only. If you are not sure which option to use, select Auto (20MHz or

40MHz).

NOTE: If you select 40MHz only for the Channel

Width setting, then Wireless-N can use two channels: a primary one (Wide Channel) and a secondary one (Standard Channel). This will enhance Wireless-N performance.

Wide Channel If 40MHz only is the Channel Width

setting, then this setting will be available for your primary

Chapter 3

Wireless-N channel. Select any channel from the dropdown menu. If you are not sure which channel to select, keep the default, Auto.

Standard Channel If 20MHz only is the Channel Width

setting, then select the appropriate channel for your wireless network. If you are not sure which channel to select, then keep the default, Auto.

If 40MHz only is the Channel Width setting, then the Standard Channel will be a secondary channel for Wireless-N (2.4 GHz). If you selected a specific channel for the Wide Channel setting, then the Standard Channel options will be available. Select the appropriate channel for your wireless network.

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.
