SYSTEM OF DECISION SUPPORT IN WEAKLY-FORMALIZED PROBLEMS OF TRANSPORT CYBERSECURITY ENSURING

This paper resolves the actual task of the development of mathematical software decision support systems (DSS) cyber security mission-critical information systems of transport (CRIST) in poorly structured and difficult tasks of formalizing the information security and information risk assessment. The paper presents developed system for decision support in weakly formalized problems of CRIST and the cyber security of objects of Informatization of the industry. The system is based on models of information security tasks description, risk assessment and cyber defense of transport in conceptual and functional aspects. Also the article presents the description of the process of forming the DSS knowledge base for circumstances related to the identification of hard-to-explain signs of anomalies and attacks.
