Wireless Local Area Networks have gained a tremendous and incredible popularity
across the computer network market over the years. However, the threats and security
fears associated with them have caused some network managers and administrator to
avoid installing wireless LAN, regardless of the numerous benefits that they provide.
Several manufacturers understand the fears, uncertainties and doubts caused by the
security problems of the Wireless Local Area Network. They realize that coming up
with a security measure to make the WLAN more secure would be a great asset and
source of profit for them. Thus, they invest in research with the goal of coming up
with a solution that satisfies the needs of the buyers when it comes to the security of
the IEEE 802.11 WLAN. As results of these researches, several measures of security
have been proposed by these manufacturers and some of them have been used by the
IEEE 802.11
