Wireless Security Checklist

Chapter 2:

Wireless Security Checklist

Wireless networks are convenient and easy to install, so homes with high-speedInternet 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, routers, and gateways, 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.

3. Enable MAC address filtering

Linksys routers and gateways 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 encryption

Encryption protects data transmitted over a wireless network. Wi-FiProtected Access (WPA/WPA2) and Wired Equivalency 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.

•• Installanti-virussoftware 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).

•• Usestrongpassphrasesthatareatleasteightcharacters in length. Combine letters and numbers to avoid using standard words that can be found in the dictionary.

Configuration

Chapter 3:

Configuration

Configuration is done through the Wireless Network Monitor (the Monitor).You can use the Monitor to check the link information, search for available wireless networks, or create profiles that hold different configuration settings.

Accessing the Wireless Network Monitor

After installing the Adapter, the Wireless Network Monitor icon appears in the system tray of your computer. If the Wireless Network Monitor is enabled, the icon is green. If the Wireless Network Monitor is disabled or the Adapter is not connected, the icon is gray.

Using the Wireless Network Monitor

The opening screen of the Wireless Network Monitor is the Link Information screen. From this screen, you can find out how strong the current wireless signal is and how good the connection’s quality is. You can also clickMore Information to view additional status information about the current wireless connection. To search for available wireless networks, click theConnect tab. To perform configuration changes or create connection profiles, click theProfiles tab.

Link Information

The Link Information screen displays network mode, signal strength, and link quality information about the current connection. It also provides aMore Information button to click for additional status information.

Link Information
