Lithuanian Annual Strategic Review

This article examines Ukraine’s legal framework for ensuring state security. The study aims to assess the current stage of its development and to propose legal improvements that align with international security standards. The findings indicate that Ukraine’s legislation lacks a unified conceptual approach to defining state security, resulting in legal uncertainty and inefficiencies in protective measures. Three key dimensions of state security are identified: substantive (a set of military actions to counter threats), institutional (the distribution of powers among authorities), and organizational-legal (a system of regulatory provisions). The concept of state security is proposed to be understood as preventive and deterrent measures undertaken by the state to safeguard territorial integrity. The study concludes that a legal framework distinguishing state security from national and military security should be developed. It further advocates legislative reforms to strengthen Ukraine’s resilience against modern threats and to ensure the effective protection of national interests.
