This paper presents the current state of the art on attack and defense modeling approaches that are based on directed acyclic graphs (DAGs). DAGs allow for a hierarchical decomposition of complex scenarios into simple, easily understandable and quantifiable actions. Methods based on threat trees and Bayesian networks are two well-known approaches to(More)
Security Safety Risk analysis Ambiguities A B S T R A C T The meaning of the terms " security " and " safety " varies considerably from one context to another, leading to potential ambiguities. These ambiguities are very problematic in the critical infrastructure protection domain, which involves multiple actors and engineering disciplines. Avoiding(More)
— Safety and security issues are increasingly converging on the same critical systems, leading to new situations in which these closely interdependent notions should now be considered together. Indeed, the related requirements, technical and organizational measures can have various interactions and side-effects ranging from mutual reinforcements to complete(More)
The digitalization of industrial control systems (ICS) raises several security threats that can endanger the safety of the critical in-frastructures supervised by such systems. This paper presents an analysis method that enables the identification and ranking of risks leading to a safety issue, regardless of the origin of those risks: accidental or due to(More)
