Modeling and Assessment of Security Risks of Intelligent Water Transport Systems

A digital test bench for the analysis of IWTS object security is presented in this paper. Digital models of the automated vessel operation system, subsystems of the global navigation satellite system and the electronic chart display and information system, as well as the system of hybrid control security (HCS), telecommunications equipment, and an IWTS object information security violator have been developed. It allows promptly identifying new threats and vulnerabilities, their direction and relevance to the object developing response measures and making justified decisions on the need to implement these measures. The specific features of the joint application of vulnerability quantitative assessments of computerized system components obtained from basic general-purpose metrics, fuzzy expert assessments and linguistic risk variables obtained for a particular object functioning are presented. The proposed models and algorithms for hybrid control security provide solutions to problems of automated search and development of effective measures to ensure the ISWT security at various stages of their life cycle.
