Perimeter security is a priority issue being addressed worldwide by aviation, marine port, military, and government agencies to counter threats of terrorism. These agencies are pursuing initiatives to find the appropriate combination of techniques that will yield productive and cost-effective solutions. At this conference last year, we presented a solution called SPAN: the Secure Perimeter Awareness Network. This year, we will detail the SPAN solution at San Francisco International Airport. In particular, this paper describes the installation, integration, and testing of multiple systems-where each system has unique capabilities-into a single perimeter security solution. Then, we detail how testing of these systems was accomplished in order to derive benefits from each so that the entire system works cooperatively and effectively.
