Security and Your Wireless Network

This week, we learned about protection mechanisms. These include firewalls and wireless networking protection. After reviewing this, it made me wonder about the status of wireless networks and how many users are actually educated enough to protect themselves. What I found is that I am guilty of not protecting myself more!

I found an article by Eric Geier on PCWorld and it really opened my eyes. I am one of those who will connect to public WiFi hotspots like Starbucks, McDonald's, or even the airport. I've never really paid much attention to whether or not my connection was secure. In the article, he states you should check to make sure any web pages you log into start with https. Otherwise, he shows clear examples of how anyone could snoop out your login information. Scary, huh?

Even scarier is that the same thing can happen on your own home network. Yes, that's right! This all boils down to setting up wireless network security by using either WEP or WPA. I happen to use WPA2, because I have heard it is better than WEP. I am not a professional on that, but I have found that WPA2 appears to work better with my wireless hardware. It seems more universal to me than WEP. Regardless of the protection method used, if you leave your home wireless network unsecured, there is nothing stopping a criminal or hacker from connecting to your network and monitoring your use. With the proper software, they could get your email login information and even your online banking information. Even scarier, right?

I have never used open WiFi networks in an illegal way, nor would I ever urge anyone to. However, I have connected to other open networks and utilized Internet connections. My grandma does not have Internet access and, at the time, I did not have a cell phone that could share the connection to a computer. I fired up my laptop and noticed that there were a few networks available, one of which was unsecured. Sure enough, I was able to surf the web and look up some information on things to do in the area, all without the owner knowing I was doing it. Depending on your Internet connection, that could be precious bandwidth being stolen from you. This is just another example of what people could use your open connection for, and a tame one at that!

The bottom line is that, with more and more people moving to wireless networks, there is a growing need for education and how to protect yourself from attacks. If you are using a public hotspot, know that any information you send over the network could potentially be snooped out by an "onlooker." Also, make sure your home wireless network is secured with a strong pass phrase utilizing either WEP or WPA protection. Educating and protecting yourself could save a lot of grief in the future!
