GAME INDICES IN INFORMATION TECHNOLOGIES FOR INTERNATIONAL COMMUNICATIONS: CYBER RESILIENCE, CYBER POWER AND CYBERSECURITY

DOI: 10.31673/2409-7292.2025.016955

Abstract

An approach to assessing the effectiveness of international cybersecurity strategies is proposed, based on the synthesis
of game theory and quantitative analysis of indicators of cooperation between states in cyberspace. The authors analyze the
strategic decisions of countries as rational players choosing between defensive and offensive strategies in cyberspace, taking
into account the possibilities of cooperation and conflict. An analysis of the main existing cybersecurity indices, such as the
Global Cybersecurity Index (GCI), the National Cyber Security Index (NCSI) and others, which assess the cyber capabilities of
states at different levels, is conducted. The development of three conditional game indices is presented: cybersecurity, cyber
resilience and cyber power, which allow assessing the level of security, resilience and offensive potential of states, respectively.
The importance of developing more flexible and accurate methods for assessing cyber capabilities that would take into account
international interactions and the political context is also emphasized. The assessment is based on a matrix of the level of
cooperation in cyberspace, which reflects the level of mutual trust and willingness to exchange data and technologies. The
methodology is demonstrated on the example of simulated data from five countries, for which the aforementioned indices were
calculated based on model interaction matrices. The results show that more intensive and evenly distributed cooperation
increases both the overall level of security and the state's resistance to attacks, and high cyberpower correlates with leadership
in global cyberspace. The proposed approach can be used for operational monitoring, analysis of weak links in international
cooperation, and scenario modeling in conditions of dynamically changing threats. The article seeks to contribute to improving
methodological approaches to cyber diplomacy, assessing the cyber potential of states, using game theory tools to understand
complex interstate interactions in the field of cybersecurity and developing more effective strategies for international
cooperation. The results of the study are of interest to cyber diplomats, cybersecurity professionals, government agencies, think
tanks, and international organizations.
Keywords: cybersecurity, game theory, cyber threats, cyber resilience, cyber power, modeling, cyber-attacks,
international communications, game indices, cyber diplomacy.
