Wireless LANs have become increasingly popular in recent years due to their advantages of simplicity, ready scalability, and flexibility. When considering the connection of wireless devices into a mission- critical network system like Military and Private Networks, such connections and/or devices are totally prohibited for a number of serious risks, threats, and vulnerabilities associated with wireless communications. The purpose of this book is to build up a general model of Wireless LANs for corporations and find proper ways to implement it with the necessary security and configuration policies in the critical organizations. It is mainly intended for the technical users who are interested in bringing wireless networking capability wherever it''s needed in the organization. The proposed user model in Chapter 7 creates a secure environment in addition to the existing security mechanisms in the access points. But, due to the privacy and security concerns of the organization, the application codes have not been explicitly published.
