Terrorism as the most dangerous social phenomenon covers a significant range of spheres of public life and is a priority issue on the agenda of the international political space, and therefore an important component of public administration. The effectiveness of countering terrorism determines the place of the state in the international arena, the trust in it on the part of international partners, international investors and internal stakeholders themselves. A distinctive feature of terrorism as a process and type of illegal activity is the need for significant financial resources for the existence of terrorist organizations and the implementation of terrorist acts. Countering the financing of terrorism as a source of its resource support ‑ is the basis for protecting the national interests and security of not only an individual state, but also society globally. Taking into account the threat to national security, the issue of the theory, organization and methodology of criminal law counteraction to the financing of terrorism is significantly updated in war conditions. Due to the lack of comprehensive studies of this issue, there is a need to substantiate the theoretical, methodological and organizational provisions of public administration in the study area.
