Secure your network

You don't go to sleep at night with your doors unlocked, so don't venture into

cyberspace without security.

Depending on your wireless router security level, consider using one or more of the following security

measures:

Enable encryption on your router. If you have not already enabled security encryption, follow the

■

router manufacturer's instructions to set the highest level of security provided by the router. WEP

and WPA are security encryption protocols.

Change the default SSID (your network name) on the wireless router and on all computers in the

■

network. The SSID should be a unique name that will not be easily associated with you.

Important: The same SSID must be specified on the router and on the computer(s), or the devices

cannot communicate.

1 To change the SSID on your router, refer to the router instructions.

2 To change the SSID on each computer in your network:

a Select Start > Control Panel > Network and Internet Connection > Network Connections.

b Right-click Wireless Network Connection and select Properties. (The Properties window is

displayed.)

c Select the Wireless Networks tab.

d Change the SSID.

Enable MAC address filtering on the router. Refer to the router instructions.

■

Use a firewall. A firewall is an essential security solution that shields your data and computer from

■

destructive hackers, data thieves, malicious email attachments, and other emerging Internet threats.

Set security on your Web browser. Setting the highest level of security on your browser is the safest

■

way to browse, but it will limit your ability to access and receive some types of information.

Note: There are additional means of securing your wireless network. Refer to your router instructions

for more information.

What Is?

access point (AP)—A single-purpose wireless

communication device that provides a wireless link

between a wireless-enabled device and a wired

network.

broadband—An always-on, fast Internet connection.

Services such as ISDN, cable modem, DSL, and

satellite are considered broadband, as compared to

dial-up Internet access.

cable modem—A device that connects a computer

to the cable television network, which in turn

connects to the Internet.

DHCP (Dynamic Host Configuration Protocol)—A

specification for service provided by a wireless

router, gateway, or other network device that

automatically assigns TCP/IP network settings (IP

address, DNS, default wireless gateway) to any

device that requests one.

DNS (Domain Name Server)—The IP address of

your ISP's server, which translates the names of

Web sites into IP addresses.

DSL (Digital Subscriber Line) modem—A device

that connects a computer to a phone line, which

in turn connects to the Internet.

DID YOU KNOW...

• Windows XP and some

router manufacturers offer

a built-in firewall.

• Firewall software also can

be purchased separately

from a local retailer.

encryption—The process of scrambling data so

unauthorized recipients cannot read it. A unique

key is usually required to decrypt the data. WEP

and WPA are security encryption protocols.

Ethernet—The most common LAN technology

(using coaxial or twisted-pair cabling) for home

and business networks, which is capable of

handling large amounts of data at speeds up to

1000 Mbps.
