Titel
Security and resilience for airport infrastructure
Abstract
The protection of critical socio-technical infrastructure is a popular research topic that gained particular interest in the last decade. In the age of digitalization, the importance of cyber-threats increases since they can lead to catastrophic consequences especially if combined with physical attacks. A prominent example of a critical sociotechnical infrastructure is an airport containing sensitive systems such as the airport operation center, the apron control and the baggage handling system. In general today, airports are well protected against individual cyberthreats and in some cases protected against certain physical attacks on individual systems. A remaining major issue is the vulnerability to combined cyber-physical threats. In the ongoing EU-H2020 project SATIE (Security of Air Transport Infrastructure of Europe), a security toolkit is being developed to face these threats in a coordinated and effective way supported by a shared situational awareness system. T he impact propagation simulation, being a part of the project's toolkit, simulates threats in an airport following a network approach to represent the system-ofsystems. In this work, we develop a model to represent not only technical components of airport systems but also the social aspect through agent-based modeling (ABM). Performance measures are defined for technical as well as social aspects of the infrastructure to quantitatively analyze the system's resilience under the influence of specific cyber-physical threats.
