Integrated "mixed" networks security monitoring - A proposed framework

Our primary concept is to develop a systemic security view of integrated, independent systems. We present-a design for the monitoring of the security of an integrated public safety "mixed" network. The Capital Wireless Integrated Network (CapWIN) is such a system, consisting of a diverse and disparate mixture of public and private networks that share information in order to provide public safety services for metropolitan Washington, DC [1]. It is imperative that the members of CapWIN be aware of the status of the other participants in order to anticipate security events. As of now, there are few means for which the members can obtain real-time information pertaining to the security status of all other parties. Our system is designed to use data fusion to provide system monitoring and feedback to all members. The system is state-based and is designed to be 1) easy to implement, 2) require minimal bandwidth, and 3) be customizable according to the preferences of each member of the network. We present an overview of the system, an analytical model for a, state-based description, and system mock-ups.
