Design for integrated WiFi defence strategy in mordern enterprise context

WiFi has been adopted into enterprise production environment in larger scale, yet the flexibility of WiFi network also exposes more vulnerability to current security defense systems and introduces greater challenges to network security for modern enterprises. In wireless world, there are many dead corners that traditional firewall and intrusion detection system cannot cover. Modern enterprises are calling for more efficient defense approaches to guarantee the safety of the information on their wireless network. Upon probing to the weaknesses of current enterprise WiFi security, this paper proposes a defense strategy with the capacities of intelligent planning and integrated reactions to remedy the weaknesses of conventional enterprise security mechanism of WiFi network. A security defense system is designed to monitor WiFi security on Physical Layer, Data-link Layer and Internet Layer of the enterprise WiFi network, and provide attack defense mechanism to minimize the damage to enterprises when their WiFi network is under attack.
