Securing Your Wireless Network
Tonight we were asked over to my wife's friends house as her husband was out of town on business. Since I stay home during the day and my wife works, we decided that I would go with her They're both American Idol fans so I took my laptop with me and I'm sitting at their kitchen table while the ladies watch American Idol. Anyway, in order for me to work and be productive while I'm here, I need an internet connection and thankfully, our friends neighbors are providing one for me. This causes me to think about wireless security. Currently I am able to connect to a few wireless (wifi) networks that are in the neighborhood that are not password protected. I'm not exactly sure why many people leave their wireless connection unsecured. Maybe they're not aware that a malicious hacker can access your computer through an open wifi network and infect it with viruses or steal your information. Thankfully for the neighbors, I'm not about to do that nor do I have any interest in doing that. Actually, I only know how to log onto their router and change a few settings, but that's enough knowledge to mess up their internet connection if that was my desire. While I admire their generosity in allowing me access to their internet connection, I think that they might want to consider stepping up the security on their router to limit outside access. Here's a few things that you should check out if you also have a wireless network that is unsecured: 1. You can login to your router settings and at least change your username and password to limit access to the router settings. Many routers default to a generic username and password which is easy to find, usually the username is something like admin, and the password is either (enter) or (password). 2. Once in your router settings, look for something that says "attached devices" or something similar. You should be able to see if other computers are currently connected to your network. 3. I would enable encryption and set a passkey on your network, that way your data will be encrypted and no one can access your internet connection without a key or password. 4. You might even consider setting the MAC address filter to on. This will only allow access to specific computers. You first need to find the MAC address of any of your computers, which is a unique number to each computer. By setting this on, you limit access to all computers except the ones that you have specifically allowed. 5. Lastly I would consider turning off the "broadcast" feature of your wifi connection. This will essentially shut off signal from being found by other computers other than your own. If you need more info, just search out the security settings for your specific router maker or refer to your router owners manual. If you are completely lost, call your local computer store and have them setup your wireless internet connection for you. |
