A New Way to Generate Automatically the Attacks Scenarios and Combine them with Safety Risks

International audienceIndustrial systems have undergone a transformation with the introduction of connected systems and digitaltechnology into their control systems, making them open to new cybersecurity threats that affect the safety of thesystem with the accidental situations. Therefore, analysing these new threats becomes crucial during risk analysis.A significant number of risk analysis approaches have been proposed to treat independently the safety andcybersecurity issues. There is a strong interest in developing risk analysis approaches that combine safety andcybersecurity, particularly in the critical process industry, which poses a significant risk to local populations andthe environment. The goal of this article is to present a new developed risk analysis approach that aims to generatethe possible attacks scenarios that can occur in industrial systems systematically in new models, and generatethese scenarios automatically using a computerized code to simplify the risk analysis process; especially for userswho are not experts in the domain of cybersecurity
