On previous entries I talked about how easy it can be to infiltrate a network, and in this entry I will provide software to protect your network from invaders. Here are the previous posts:

How Secure is your Network
Wi-Fi defense systems find unique visitors on your network. You may have heard of “war diving.” It is people driving around with their laptops, iPods/iPhones, and antenna devices looking for unsecured networks. In one test of driving around in Las Vegas they found over 100 open networks in just a few minutes. Some carry GPS units and mark these unsecured networks and upload the longitude and latitude coordinates to websites.
Now, pair that up with software such as Network Stumbler, which scans for networks roughly every second and logs all the networks it runs into–including the router's SSIDs, the AP’s MAC address, the best signal-to-noise ratio encountered, and the time you crossed into the network’s space. Most war-drivers do it for 'kicks' but some have more harmful intentions.

SpyderSoft Wi-Fi Defense was designed with the mainstream, non-technical consumer in mind, yet is powerful enough to offer security benefits to even the most advanced user.
The technology detects all devices on the network, provides identifying information to assist the owner in designating each as Friend or Foe, and seamlessly locks-down the network to allow only approved devices. Adding a new device or allowing a visitor to join the network is also an easy task, and the application ensures that you maintain a locked-down network. At all times, SpyderSoft Wi-Fi Defense continues a background scan to detect new and/or unauthorized devices.
