Building a Private Infrastructure
In the majority of cases, when companies build their wireless infrastructure they often fail to account for privacy concerns. Security is often an afterthought, and by then it is a simple and easy matter for someone with a laptop and wireless NIC to use freely available software to roam directly onto your wireless network and have almost unlimited access to your entire intranet.

The most common tools include “sniffers” that can listen to the network to get user passwords and steal confidential documents transmitted directly from your e-mail server. These actions are no less than corporate espionage. The most common attack is from people who understand the building blocks of your network and sit just outside your building, roam onto your wireless network from their cars, and record all your network activity.
