Wireless Security

Did You Know...

Nearly half of all wireless networks have no protection.*

Another 40% use an outdated security protocol (WEP)* that can be cracked in less than 10 minutes by anyone who can read instructions. (not just hackers)**

Why do you need security?

Many people reason that they don't keep state secrets on their computer, so they don't need wireless security. That isn't true. On an unsecured wireless network, the data that you send back and forth to websites (i.e. your credit card number or online banking info) is also vulnerable, in addition to the files on your computer.

Here's another scenario: An identity thief is driving around, detects your unsecured wireless network, and stops. Using your wireless network, he makes fraudulent charges or transfers funds. The next day, the police show up at your door, thinking that you did it. Unfortunately, YOU CAN BE HELD LIABLE for crimes which are committed via your unsecured wireless network.

What should you do?

All home networks should be upgraded to the WPA security protocol. The older security protocol (WEP) is now considered obsolete, so even if your network says "Secured", you may not be safe!! Upgrading to WPA is usually done by changing some settings in your router and computers. In a few cases, downloading an update from the manufacturer or buying new equipment is necessary. Refer to the user manuals of your wireless equipment for details about how to access and change the settings.

Wireless networks at businesses, or other networks which handle a lot of sensitive data should consider additional measures such as MAC filtering lists or hidden SSIDs.
