ADMINISTRATIVE AND LEGAL MECHANISM FOR COUNTERING COMPLEX THREATS IN THE FIELD OF NATIONAL SECURITY

The article provides a comprehensive analysis of the administrative and legal mechanism for countering complex threats in the field of national security of Ukraine. It reveals its theoretical and legal nature, institutional and functional structure, and procedural and legal tools for ensuring state security. It is proved that administrative law serves as a system-forming factor in the organization of public administration in the security sphere, as it ensures the normative determination of competencies, the regulation of control and coordination procedures, and the accountability of public authorities. The study defines the fundamental principles of administrative and legal regulation of national security, including the rule of law, proportionality, publicity, accountability, and the preventive orientation of management actions. Particular attention is paid to the institutional architecture of the security system, which includes the National Security and Defense Council of Ukraine, the Security Service of Ukraine, the Ministry of Internal Affairs, the State Service of Special Communications and Information Protection, and other central executive bodies. The mechanisms of interagency coordination, parliamentary and public oversight are revealed as key elements of the democratic legitimacy of security policy. The role of administrative and legal procedures in ensuring a continuous security management cycle – from risk identification and monitoring to response and recovery – is determined. In the context of current transformations, the importance of digitalization and European integration processes for modernizing the legal mechanism of security is emphasized. The need to introduce legal norms regulating electronic interaction between government bodies, cybersecurity, data processing, and cyber liability is substantiated. It is shown that digital technologies form a new model of national security management based on analytical adaptability, risk forecasting, and decision-making transparency. The study concludes that the administrative and legal mechanism for countering complex threats in the field of national security is an integrated system capable of ensuring the strategic resilience of the state, legal predictability of governance, and effective coordination of security actors within the European legal framework.
