Item A Multi-layer Approach through Threat Modelling and Attack Simulation for Enhanced Cyber Security Assessment(Association for Computing Machinery, 2024-07-30) Iturbe, Eider; Arcas, Javier; Rios, Erkuden; Toledo, Nerea; CIBERSEC&DLT; Medical TechnologiesThere is a growing concern about the dynamic landscape of cyber security threats escalating, and the need for improvement in defence capabilities against emerging sophisticated incidents. In response, this paper presents a solution called the Cyber Incident Simulation System, which enables system security engineers to simulate cyber-physical attacks and incidents without the requirement to affect or disrupt the ongoing business operation of the system. Leveraging graph-based threat modelling and AI-generated incident data, the system empowers professionals to predict the effect of the incident within the system under study. The synthetic data is used by anomaly-based Intrusion Detection Systems (IDSs) and other additional security controls to improve their detection algorithms to enhance their accuracy and effectiveness. The Cyber Incident Simulation System is designed to enhance the cyber security measures through the simulation of various incident scenarios.
