Playing Russian Roulette at McDonald's!

There are two types of wireless networks: (1)Public networks, such as at Barnes and Noble, Panera, Starbucks, airports, or McDonald's, and (2)private networks, including the peer-to-peer, gamer and server networks found in many homes.

The dangers of public wireless networks are not well recognized. One patron surfing on his own notebook at a corner table may, in fact, be taking advantage of another patron's computer, in spite of secured passwords, through packet sniffing. Equally at risk are home wireless networks, whose signals may reach out to the curb or to an unknown neighbor on a street behind.
