Petri Net-Based Approach for “Cyber” Risks Modelling and Analysis for Industrial Systems

Today, industrial systems are large, complex, and increasingly vulnerable. Specifically, due to the current digital transformation, the industry 4.0 creates crucial cyber-risks and cyber-security challenges. In this context, risk modelling and impact analysis has become a crucial research topic. Based on the formal modelling and performance analysis power of Petri Nets (PN), this paper represents a summary of our methodological approach for “risk” modelling and “impact” analysis of cyber vulnerabilities and / or other critical events. The applicability of the developed approach is demonstrated on a real-life industrial system.
