INTEGRATIVE APPROACH TO THE ANALYSIS, MODELING, AND ENSURING CYBER SECURITY OF CRITICAL INFORMATION INFRASTRUCTURE UNDER MODERN THREATS

Abstract

The present study explores contemporary approaches to the analysis, modelling and assurance of cyber security of critical information infrastructure in the face of modern threats. This text focuses on the utilisation of intelligent methods and advanced technologies for the protection of critical information infrastructure (CII). The objective of the present study is to employ an integrative approach to analysing, modelling, and ensuring the cyber security of CII in the face of contemporary threats. The methodological foundation of the study is a comprehensive analysis of scientific literature dedicated to the application of intelligent methods and technologies for the protection of CII. This includes both fundamental theoretical developments and practical aspects of implementing modern cyber security approaches, as well as experimental modelling of fraud detection processes in the CII of the financial sector. This modelling was conducted by the authors using artificial intelligence (AI) methods. A comparative analysis of concepts proposed by modern researchers is given particular emphasis, with the objective of identifying the main trends, development prospects, and potential areas for improving existing CII protection systems. In relation to the outcomes of the extension of scientific sources, it was determined that intelligent methodologies founded on machine learning and AI represent pivotal technologies for the effective safeguarding of critical infrastructure within the financial sector against contemporary cyberattacks and security threats. The results of the modelling of fraud detection processes in the CII of the financial sector of the economy allow an assessment of the effectiveness of the methods used, determination of their advantages and limitations, and formulation of recommendations for further improvement of cyber protection systems for the CII of the financial sector of the economy. The employment of an integrative approach, encompassing threat analysis, simulation modelling, artificial intelligence, and contemporary cyber defence technologies, facilitates the enhancement of the security of critical infrastructure and the effective response to emergent threats. The proposed solutions have the potential to facilitate the development of highly effective cyber defence systems in various critical infrastructure industries, including the financial, energy, and government sectors.
