Securing a Wireless Network

One of the things that annoy me the most is the lack of concern many folks have about security. They buy a computer with AV installed and never, never ever update it or renew the subscription.

The same applies to wireless routers. Most people will install it leaving the defaults in place. You might as well post a message outside your house saying “Free Internet HERE!’….

There are a lot of things that one should do. Here’s a list of some simple steps you can take. You won’t have a really secure network, but at least you will have closed the door… W.r.t. Tip 1, I would point out that WEP is completely unsecure these days. It’s almost useless. It was, for example, the protocol used by T.J. Maxx to secure their network when they were hacked. Lately, there are published techniques for breaking WPA. If your router and wireless cards support it, best to implement WPA2 which remains about as secure as you can get at home.
