Global financial transformations provoke shifts in financial systems that can threaten countries’ economic security. Further integration of the CEE states to the global economy will be accompanied by the increasing dependence of their financial markets and economic security on global financial challenges. The study aims to identify the relationship between global and regional financial trends that shape CEE countries’ economic security and reveal the shifts in the CEE region’s economic security under the influence of global financial transformation. The global financial transformations are the object of the study. Comparative analysis of the dynamics of financial transformations in the world and the CEE countries is made using structural analysis and methods of economic and mathematical modeling of trends. Given the heterogeneity of the CEE states’ financial development, global financial transformations have different manifestations in these countries. The relationship between global and regional indicators of financial transformation proved to be ambiguous. The regional dynamics of stock market capitalization, debt securities, and external debt fit corresponding world indicators’ dynamics. The indicators of global and regional official reserves and bank assets are moving in different directions. The region’s economic security challenges are great volatility of stock market capitalization, growth of external debt burden, and uneven distribution of official reserves. The obtained results should be considered when identifying financial threats affecting the CEE countries’ security and developing relevant policies for shaping the region’s efficient financial system.

The article presents and describes innovative technologies of training in the professional training of Masters. For high-quality training of students of technical specialties, it becomes necessary to rethink the purpose, results of studying and means of teaching professional disciplines in modern educational conditions. The experience of implementing the chatbot tool in teaching the discipline “Mathematical modeling of socio-economic systems” in the educational and professional program 124 System Analysis is described. The characteristics of the generalized structure of the chatbot information system for investment analysis are presented and given: input information, information processing system, output information, which creates a closed cycle (system) of direct and feedback interaction. The information processing system is represented by accounting and analytical data management blocks. The investment analysis chatbot will help masters of the specialty system analysis to manage the investment process efficiently based on making the right decisions, understanding investment analysis in the extensive structure of financial management and optimizing risks in these systems using a working mobile application. Also, the chatbot will allow you to systematically assess the disadvantages and advantages of investment projects or the direction of activity of a system analyst, while increasing interest in performing practical tasks. A set of software for developing a chatbot integrated into training is installed: Kotlin programming, a library for network interaction Retrofit, receiving and transmitting data, linking processes using the HTTP API. Based on the results of the study, it is noted that the impact of integrating a chatbot into the training of Masters ensures the development of their professional activities, which gives them the opportunity to be competent specialists and contributes to the organization of high-quality training.

The study substantiates the urgent need to train qualified specialists capable of responding to cyber incidents and countering cyber threats in a short time, conducting state audits and creating effective management systems for information security and cybersecurity. The aim of the work is to reveal the ways and features of the organization of the study of mathematical disciplines in order to effectively train higher education students majoring in 125 «Cybersecurity». The role of the mathematical component of cybersecurity and the organization of the educational process of mathematical disciplines for the purpose of effective professional training of future cybersecurity specialists is considered. It is concluded that most professionally-oriented disciplines that provide basic knowledge in all aspects of information security are based on fundamental mathematical training. The study argues that the applied problems solved by the students of the specialty 125 «Cybersecurity» must meet the methodological requirements for real practical content, which provides an illustration of the practical value and significance of the acquired mathematical knowledge in the cyber- and/or information security field. The solution to the problem of improving the quality of mathematical training of the students is considered through the use of intra-subject and interdisciplinary links, the introduction of applied orientation of mathematical disciplines and the principle of continuity. The paper presents examples of professionally oriented tasks that are offered to higher education students majoring in 125 «Cybersecurity» studying mathematical disciplines. It is proved that the introduction of applied orientation of mathematical disciplines creates the necessary conditions and attracts students to the professional sphere, which is an important step towards improving the quality of training of cybersecurity professionals.

The publication is aimed at developing theoretical bases for research of the causes and consequences of global financial crises, as well as systematizing the typology of global financial crises to determine effective and efficient measures to influence their course and reduce losses from their consequences. Scientists-economists of different scientific schools provide unequal explanations, definitions and substantiations of the essence and causes of the development of global financial crises. In all cases, global financial crises cover financial markets, money turnover and credit, international finance; they manifest themselves through the rapid growth of interests, debts, reduction of loans, large-scale downfall in the securities exchange rate, massive losses in the market of derivatives, uncontrolled decline in exchange rates, etc. The introduction of effective and efficient measures to prevent global financial crises in early stages of their development can significantly affect their course and reduce losses from their actions and consequences. A typology of global financial crises is proposed, which takes into account the connections of their causes and consequences on the following grounds: the coverage of the monetary and financial system, the level of international economic relations, and perturbing factors. The latter cause global financial crises by implementing the cause-and-effect economic mechanisms. This results in the occurrence of contradictions between economic needs and a monetary and financial system.
