DEVELOPMENT OF A DECISION SUPPORT SYSTEM BASED ON EXPERT EVALUATION FOR THE SITUATION CENTER OF TRANSPORT CYBERSECURITY

摘要

The work is devoted to the development of the mathematical support of decision support systems (DSS) for information and cybersecurity of information and communication transport systems (ICTS). There was improved the algorithm on the basis of the Delphi method for carrying out a survey to assess the ICTS security using the DSS. The algorithm is adapted for on-line mode for solving the problems of situations development forecasting related to information security and to prevention of the destructive influence of cyber attacks on ICTS. There was proposed a model for structuring of heterogeneous information obtained by interviewing the experts and for forming a knowledge base of DSS. One of the motivating reason for this research was the need to develop a fairly simple for algorithmic implementation, but effective tool for the experts work online, assessing the information security of a particular information object. On the basis of the proposed model, there were developed and tested automated tools for depth ICTS security analysis in the on-line mode using the generation of questionnaires for the research conducting by Delphi method. There were presented the results of approbation of the developed tools for the practical tasks of ICTS cyber security ensuring. It is shown that the proposed solutions allow to reduce financial and time costs in the process of on-line expert evaluation organizing and contribute to its quality and effectiveness.
