PRAETORIAN: A Framework for the Protection of Critical Infrastructures from advanced Combined Cyber and Physical Threats

Combined cyber and physical attacks on Critical Infrastructures have disastrous consequences on economies and in social well-being. Protection and resilience of CIs under combined attacks is challenging due to their complexity, reliance on ICT systems and the interdependences between different types of CIs. The PRAE-TORIAN framework was designed to address these challenges, by integrating components responsible for detecting both cyber and physical threats. Additionally, it forecasts how the combined attacks will evolve and their cascading effects on interdependent CIs. The PRAETORIAN framework was demonstrated based on a realistic scenario in the Zagreb airport, combining both physical and cyber attacks.
