A Wi-Fi enabled device such as a personal computer, video game console, smartphone, and digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. This article describes sniffing techniques that attackers have used in Wi-Fi, and suggests various security defensive strategies. We describe how SSIDs can be determined, how a sufficiently large number of frames can be collected so that WEP can be cracked. We conclude the article with several ways that will help improve security at a wireless deployment site.
