Özet
This research develops a predictive framework for cyber-induced navigational risk escalation in narrow canals and straits. Restricted manoeuvring space, dense traffic, and dependence on digital navigation systems amplify the operational consequences of cyber disruption in these environments. An expert-defined Bayesian Network (BN) was constructed to represent the causal relationships between ten risk node (RN) cyber-risk indicators, three intermediate degradation states, and the top event defined as cyber-induced navigational risk escalation in narrow waters. This top event does not represent attack initiation or attack occurrence directly; rather, it denotes a navigation-level risk state arising from the interaction of cyber-relevant vulnerabilities, compromised navigation information, and incorrect situation assessment. The BN benchmark was fitted using a Noisy-OR-type formulation. It was then evaluated alongside three machine-learning (ML) baselines: logistic regression, random forest, and gradient boosting, trained on the same RN predictors. The findings demonstrate the complementary strengths of both approaches, supporting the development of more reliable and explainable cyber-risk assessment tools for safety-critical maritime operations in narrow waterways. Because the TE labels were generated through BN-consistent simulation, the results should be interpreted as a controlled methodological proof-of-concept rather than as empirical validation of real-world maritime cyber-attack prediction accuracy.
