Abstract |
This research is devoted to solving the issue of increasing the level of cybersecurity in large companies through the introduction of modern blockchain technology. The urgency of this problem has been determined for enterprises that have faced with cases of cyber fraud, initiated not only by hackers but also by company employees. The authors have proposed a systemdynamic model of the company’s cybersecurity system built using blockchain technology. The choice of this modeling tool gives an ability to create a computer model of a complex cybersecurity system for further effective design of the proposed modification. The authors have made the main emphasis on reducing the threat associated with the human factor since, according to statistics, 34% of cases are accounted for by the system vulnerability due to user activities. The researchers have developed a diagram of causal relationships, which imitates the process of personnel behavior in the environment of an enterprise automated information system, provided that a person intentionally or unintentionally carries out fraud. The model takes into account the primary condition when any transaction initiated by a person registered in the system has fixed in its blockchain. Thus it reflects the system reaction in case of illegal actions, which further creates the basis for the development of a set of preventive measures. The authors have proposed a system-dynamic diagram based on an analysis of the causal relationship diagram. The article describes the components of the model in the form of differential equations and conducted experimental modeling for various values of some parameters at the initial level of others to identify the sensitivity of the system. The results have made it possible to conclude about the increasing system response in cases of employee fraud in the environment of the company’s automated information system if it bases on blockchain technology. |
