This paper describes the coordinated security perimeter, a model for extending protection for enterprise networks far beyond the safe confines of headquarters. This is achieved through central management, secure wireless connectivity and scalable secure switching.

Branch offices, retail stores, remote sites and mobile workers in distributed enterprises need to be connected to headquarters. At the same time, headquarters needs a simple way to maintain security policies across the distributed enterprise. But as the network continually stretches to encompass them, it becomes more difficult for IT to manage, secure and maintain compliance companywide. The coordinated security perimeter is a model that gives the distributed enterprise the central management and secure wireless connectivity it needs to defend itself against unceasing attacks on the network.
