The thesis provides the solution to the scientific problem of theoretical and methodological justification and development of practical recommendations for the use of a set of mechanisms and procedures for developing and implementing strategies that affect the level of national security and create a certain state to counter modern threats. At the same time, in order to regulate the issues of updating and ensuring the development of Ukraine’s national security structure on the one hand and timely detection, prevention and neutralization of real and potential threats to Ukraine’s national interests on the other, it is proposed to apply strategy criteria and methods in public administration practice.
The studied conceptual and categorical apparatus of strategizing in the field of public management of the security environment of Ukraine allowed to determine the factors, to outline the time horizon and the frequency of forecasting the future security environment.
The essence of the transformation of views on the security environment in the context of globalization has singled out the phenomenon of war as an effective basic tool of international relations, which increases the role of non-traditional weapons, a hybrid combination of which has a multiple increase in destructive influence.
The analyzed threats to the future security environment of Ukraine - key dangers in the military sphere and the realization of national interests (the main of which remains the armed conflict in eastern Ukraine) determined the feasibility of using a scenario analysis by generating possible scenarios for crisis.
The revealed features of long-term forecasting of the security environment of Ukraine on the basis of global tendencies of development of the international situation allow to carry out the forecast of development of scenarios of a strategic situation and possible character of the future wars and military conflicts (taking into account the specificity of the listed phenomena in terms of the accuracy of recurrence, place and time, composition of participants, used weapons and military equipment, political configuration).
The analysis of the capabilities of the security and defense sector to ensure the national security of Ukraine showed a significant limited resources for a guaranteed response to current threats to national security of Ukraine given the number of unresolved issues (mostly material, financial, coordination, management in crisis situations). Using this approach, changing the level of military threats becomes an appropriate target function of the security and defense sector of Ukraine, which will depend on the implementation of the capabilities of each of the components involved in the fight in the selected version of their integration. This, in turn, makes it possible to make more rational use of available forces and means, to avoid duplication of tasks and uneconomical use of extremely limited resources allocated in Ukraine to ensure its military security.
The sources, preconditions and regularities of occurrence and manifestation of threats that affect the system of public administration in the field of state security are considered. The main stages of the process of their systematization are determined. The main classification features are identified and a multi-criteria classification of threats to the public administration system based on hierarchical analysis is developed. The key threats to this system, which have an impact on all spheres of national security of Ukraine, which have a complex nature of threats to the system of public administration in the field of national security (information, cyber, corruption) are identified.
For the first time, the thesis substantiates the scientific and methodical apparatus of complex application of mechanisms and procedures of development and realization of strategy of maintenance of a sufficient level of national security of the state in the conditions of a modern geopolitical and military-political situation, existing and forecasted threats is compiled. strategizing the security environment of Ukraine in the field of public administration; a comprehensive methodology for determining the tasks of the subjects of the national security system; scientific and methodological apparatus for the distribution of tasks and determining the capabilities of the security and defense sector. The application of this scientific and methodological apparatus allowed to develop recommendations for strategizing public administration in the field of national security of Ukraine.
It should be noted that the dissertation proposes ways to assess and predict trends in the impact of threats to the realization of national interests (generating possible scenarios for the emergence and development of crisis situations that may threaten the realization of national interests).
