MECHANISMS FOR ENSURING DIGITAL SECURITY IN THE PUBLIC ADMINISTRATION SYSTEM OF UKRAINE DURING MILITARY AND CRISIS CHALLENGES

Abstract

Introduction. The article analyzes the evolution of the digital security architecture of the public administration system of Ukraine in the conditions of a full-scale war. It is proven that the strategic transformation of approaches to information protection - from the physical placement of servers to the use of cloud technologies and the concept of "zero trust" - has become a key factor in ensuring the continuity of public administration and the provision of public services during unprecedented cyber threats.

The purpose of the article is a comprehensive analysis of institutional, technological and managerial mechanisms for ensuring the digital resilience of state authorities and local governments, as well as outlining the prospects for the transition from a reactive to a proactive model of cyber defense.

Materials and methods. The study is based on the analysis of the regulatory framework, digitalization strategies and the experience of the functioning of the critical information infrastructure of Ukraine during the war period. The methods of system and structural analysis, modeling of management processes, as well as the synthesis of best practices of international cooperation in the field of cyber defense were used.

Results. The institutional architecture of the cybersecurity system and the role of key actors (DSSZZI, Ministry of Digital, SBU, NCCC) were studied. Technological vectors of protection were identified, in particular, the successful implementation of the “Diya” ecosystem and the “Trembita” system. Critical vulnerabilities of the system were identified, including staff shortages, technological obsolescence of local infrastructure, and energy instability. The need to implement the “Zero Trust” model, create a national cyber reserve, and integrate artificial intelligence algorithms into threat monitoring systems was substantiated.

Prospects. Further research should focus on the implementation of European directives, in particular NIS2, the development of domestic technological solutions to reduce dependence on external suppliers, and the formation of a culture of “cyber resilience as an everyday norm” through the development of professional competencies of civil servants.
