Une approche de l’analyse des risques des systèmes de contrôle industriels combinant sûreté et sécurité : le cyber Noeud-Papillon

Abstract : The increasing importance of digital technology in chemical process industry creates new vulnerabilities that can be exploited to provoke dangerous phenomenon fore people or environment. However, nowadays, safety and security are assessed separately and possible physical consequences of cyberattacks are not evaluated It is therefore necessary to integrate the consideration of cybersecurity in the global analysis of risks to human health and the environment. In this paper, a new method is proposed by considering safety and security for a probability evaluation during industrial risk analysis. This approach combines Bow-Tie Analysis (BT), commonly used for safety analysis and the Attack Tree Analysis (AT), recently introduced for security analysis of computer control systems. The combined use of BT and AT provides an exhaustive qualitative investigation of security and safety scenarios, and a qualitative evaluation of the likelihood of these scenarios. The definition of ATBT combined model is presented
