Abstract

Article describes the model developed for the module of port information system cyber security facilities funding decision making support system. The model is based on multistage game theory toolkit. The solution offered allows an opportunity for managers of information safety systems, particularly port information systems and technologies, to carry out preliminary assessment of financial strategies for development of effective cyber safety systems. The distinctive feature of the model is the assumption that the defending party does not have full information on the financing strategies of the attacking party and on the state of its financial resources used to break cyber security barriers of the port information system. The solution employs mathematical apparatus of bilinear turn-based multistage quality game with several terminal surfaces. A multiple-option simulation experiment was carried out to ensure validity of the model. The results of the experiment will also be described herein. Thus, in the article at the first time, decision of the game was shown for all cases of the correlation of game parameters for the protection side of the port information system (PIS) and hackers seeking to overcome the boundaries of cybersecurity. The solution found in the article will be useful for the created decision support system, in particular, for the situation when the attacker uses a mixed financial strategy of hacking the information system.
