Cyber Security Risk Assessment of Intelligent Ships under Multi-source Attacks

Automated and semi-automated ships have developed rapidly in recent years, but various external communication links have introduced some external threats. To solve the unknown impact of multiple attacks on intelligent ships, a cellular automaton is proposed to model the risk propagation process. We identify risk assessment indicators from the perspective of attack-defense confrontation and analyze the risk propagation situation from six different angles. Based on the experimental results, we identify the system’s weak nodes and propose cyber security protection suggestions to reduce the loss caused by multisource attacks on the system.
