Most homes and businesses with a high-speed Internet connection and more than one computer connect to the Internet using a wireless connection. Wireless networks offer great convenience allowing you to work anywhere in your home or business without the mess of cords and cables.
Wireless networks are relatively easy to set up. Basically, you simply connect a wireless router to your cable or DSL modem. The wireless router then broadcasts a signal through the air to nearby computers indicating network and Internet access is available.
However, most people don’t realize that, unless you secure your wireless network, anyone within several hundred feet can connect to it and use your Internet connection – without your knowledge or permission. This leaves you at serious risk and liability.
It’s like leaving your back door wide open.
The Dangers of an Unsecured Wireless Network
An unsecured wireless network allows your neighbors, potential hackers, and even criminals to access your computers and use your Internet service. Such people may use your network to download illegal content and send spam and viruses.
It also allows them the ability to look at all of the files on your computer, including pictures, documents and other personal information. With the right software, they can watch everything you do online – including making purchases, booking vacations, and online banking.
If someone commits a crime using your Internet connection, the activity can be traced back to your account and you could potentially be held responsible.
How to Protect Your Wireless Network
- The first step is to use encryption. Most routers today have the ability to encrypt your wireless communications, but the feature is turned off by default. It requires you to manually turn it on. The best and strongest form of encryption is WPA, or Wi-Fi Protected Access. If you have this option, select it. It provides the greatest security against hackers. The other form of encryption is WEP, or Wired Equivalent Privacy. It provides basic protection for your wireless network, although it can be broken into by sophisticated hackers. Still it is better than no encryption at all.
- Second, change your router’s pre-set password for administration. All routers have a default password that allows you to setup and configure the router. These passwords can be easily found on the Internet. Changing the password to something only you know will make it more difficult for hackers to guess and prevent others from accessing your router.
- Third, turn off identifier broadcasting. Wireless routers send out a signal to nearby computers announcing that a wireless connection is available. If this signal is turned off, unwanted people will no longer know that your wireless connection can be joined.
- Finally, protect all of your computers with good antivirus software and a firewall. Keep them up-to-date.
