Scientific and Methodological bases of Complex Assessment of Threats and Damage to Information Systems of the Digital Economy

The article examines the scientific and methodological basis of a comprehensive assessment of threats and damage to information systems of the digital economy. The information infrastructure and tasks of the digital economy have been defined. Sources of information security in the digital economy sectors and their information security requirements have been studied. The results of the analysis of the situation in the countries of the world on the Global Cyber security Index are shown schematically. The graph of the dynamics of cybersecurity expenditures in the ICT segments is shown. It is argued that cybersecurity, which is formed and developed through the use of digital systems, is a priority. Many goals and methods of cyber-attacks are given on the platform of the 4.0 Industrial revolution. Cases of information security violations in the digital economy and the processes of assessing the damage caused by them have been studied. Generalized criteria for assessing information damage in the digital economy have been proposed. Threats to information and communication systems and classification of damage are given. A structural scheme of the conceptual model of threats and damage to information systems and resources in the field of digital economy of Azerbaijan has been proposed. An expert description of the ways in which information threats are disseminated has been developed using a fuzzy approach. The main types of damage caused by threats to the security of information systems are given. The security aspects of the abundance and surplus of information in the digital economy are shown. The directions of increasing the level of security and confidence in the digital economy and the structures to ensure its security are given. The main directions of information security in the digital economy have been identified, the directions of ensuring its security and increasing its confidence have been identified. Commonly used universal base technologies have been proposed in the digital economy sectors. Some methodological approaches to integrated risk and damage assessment in the digital economy have been explored. A scientific-methodological approach based on fuzzy methods has been proposed for the implementation of complex risk and damage assessment in the digital economy. Purpose of the research. The main purpose of the research in the article was to develop a scientific and methodological bases for identifying and comprehensively assessing the scope of possible threats, dangers and damage to information systems that make up the infrastructure of the digital economy in its formation conditions. Attention was paid to the development of recommendations on promising areas for improving multi-criteria expert assessment methods in increasing the effectiveness of management of threats and damage to information systems of the digital economy and the assessment of their performance. By applying the results of multi-criteria expert assessments in decision-making processes it has been possible to get results. Attempts have been made to classify threats and damages in information systems and resources in the sphere of digital economy and to develop a conceptual model of their impact. The spread of information threats using a fuzzy approach has been described by expert methods. Defining the main directions of information security in the digital economy, defining the directions of ensuring security and increasing confidence, using universal basic technologies to ensure security in the digital economy sectors are also included in the research goals. One of the goals was to propose the main stages of an approach based on fuzzy methods for the implementation of integrated risk and damage assessment issues in the digital economy. Research methods used. Research methods such as system analysis, correlation and regression analysis, mathematical and econometric modeling methods, expert assessment method, measurement theory, algorithmization, ICT tools and technologies have been used in the development of scientific and methodological bases of complex assessment of threats and damage to information systems of digital economy.
