MODEL - AND SIMULATION DRIVEN SYSTEMS - ENGINEERING FOR CRITICAL INFRASTRUCTURE SECURITY ARCHITECTURES

The design of systems that support the protection of critical infrastructures or state borders against various threats is a complex challenge. This requests the use of both modelling and simulation in order to reach the operational goal. Threat scenarios like terrorist attacks, (organized-) crimes or natural disasters involve many different organisations, authorities, and technologies. These systems are often operated only by implicit known processes and diverse operational guidelines based on dissimilar legislations and overlapping responsibilities. In order to cope with these complex infrastructure systems and their interconnected processes, a scenario- and architecture based systems engineering approach must be implemented to design a solution architecture compliant with the requirements, internal and external demands. This paper gives an overview of the developed approach towards the system architecture and explains the different engineering steps in order to implement this architecture for real use-cases.
