Automatic Discovery of Cyberattacks
2024 IEEE International Conference on Cyber Security and Resilience (CSR)We present a method for the automatic discovery of cyberattacks within distributed information systems under abstract cost constraints. It is based on a formal model of cyberattack propagation generated from the specification of software and hardware architecture enriched with access control information.
