In historical retrospect, our country built its own national security system of Ukraine, which declares generally accepted norms of international law, which allowed the country to establish its own European identity and launch a complex process of transformation of society and the national security system. The events of recent years in Ukraine define corruption in the conditions of martial law in Ukraine as a threat to the national security of the state of Ukraine as a whole. In this context, the President of Ukraine recognized the slow fight against corruption in the conditions of martial law in Ukraine as the main obstacle to the development of Ukrainian statehood. In the course of the study, the issues of preventing and countering corruption in the conditions of martial law in Ukraine, which are of a systemic nature, are considered in the scientific plan, in particular: administrative and legal characteristics of corruption crimes, since administrative corruption offenses are not defined by the legislator as socially dangerous, but they cause certain damage material, moral or other social relations, the boundaries of which are defined in accordance with the Law of Ukraine „On Prevention of Corruption", according to the document they are classified as another group of offenses, in particular „offences related to corruption", the legislator interprets this as „acts that do not contain signs of corruption, but violate the requirements, prohibitions and restrictions established by this law, committed by the person specified in the first part of Article 3 of this law, for which the law establishes administrative, disciplinary or civil liability"; problems of combating corruption in the conditions of martial law in Ukraine; administrative responsibility for certain types of corruption crimes; conflict of interests in the conditions of martial law in Ukraine; reforming the system of state authorities. During the research, classical and author's approaches to the development of administrative and legal principles for the prevention and counteraction of corruption were analyzed, and positive theoretical and practical foreign experience was used. The relevance of the proposed research lies in the fact that scientists are paying attention to the solution of corruption problems in certain areas, and specifically, until now, the problem of preventing and countering corruption in the conditions of martial law in Ukraine has not been solved, taking into account the conceptual approach that would ensure the effective functioning of prevention measures and combating corruption based on the author's proposed model of administrative and legal principles for preventing and combating corruption in the conditions of martial law in Ukraine, which led to the choice of this topic of the article.
