Dangers of Public Wi-Fi

Nowadays, IT services like IT connectivity are available at all times and in many places even for free. But there is a catch: there are many dangers to your IT security when using public Wi-Fi networks in coffee shops, airports, hotels, to surf the Internet. Hackers present a bigger threat than ever to public Wi-Fi users because of the fact that they can make a user's browser show fake websites or steal data from its PC.

This is all according to IT engineer Mike Kershaw that developed the Kismet wireless network detector and intrusion-detection system. He said that "Once you've left Starbucks, you're owned. I own your cache-control header. You're still loading the cache JavaScript when you go back to work. Open networks have no client protection. Nothing stops us from spoofing the [wireless access point] and talking directly to the client." Many IT companies are trying to solve this problem.
