Model-based airport security analysis in case of blackouts or cyber-attacks

Kurzfassung

With the increasing exposure of critical infrastructures to external factors, critical infrastructure protection gained attention within security research. To develop protection methods the effect of external factors on critical infrastructures has to be known. In this paper we present an event-based, dynamic modeling approach using power flow analysis and network flow analysis to simulate this effect on the critical airport infrastructure airport with object-based programming. Network component objectification is used to treat the highly interconnected cyberphysical system as a two-layered system with separated cyber and physical properties. Network stability and cyber infection status is checked with two control feedback loops checking grid stability and infection status. Therefore with given object load powers and network interconnections the working capability of infrastructure parts can be predicted for various scenarios and used as input for passenger flow simulations or economical prognosis.
