Resilience quantification for critical infrastructure: Exemplified for airport operations

In the EU-H2020 project SATIE (Security of Air Transport Infrastructure of Europe), a security toolkit is developed to protect airport infrastructure from various cyber-physical threats. One of these tools is the Impact Propagation Simulation (IPS) which is designed to estimate impacts of incidents in an airport and thus to quantify the system’s resilience under varying conditions. IPS consists of two main engines, i.e. a network model and an Agent-Based-Model (ABM). Exemplified for Malpensa airport in Milan, a specific cyber-physical threat scenario is analyzed and the resilience of the impacted systems is discussed.
