Introduction. Currently, 75% of the population of the Russian Federation live in cities, the vast majority of which are municipalities. All of them are part of the constituent entities of the Russian Federation. The federal state structure of the Russian Federation, due to the scale of the territory of our country, allows regional government bodies to take into account various features of threats and dangers characteristic of certain subjects of the Federation. In this regard, it seems appropriate to analyze the legal consolidation and practice of implementing the powers of regional authorities in the field of security and to determine the features of its provision depending not only on the specifics of the subjects of the Russian Federation, but also on the legal and factual characteristics of the city. Theoretical analysis. The problems of ensuring regional security have been in the focus of attention of legal scholars for a long time, but the security of cities, which constitute an important part of the territory of the subjects of the Federation, has not been given due attention. The live analysis of the studies devoted to the problems of regional security showed that this level of security is recognized as basic, implemented primarily by government bodies of the subjects of the Federation in all spheres of life established by law. At the same time, attention is focused on the study of various categories of cities and the mutual influence of urban and regional security. Empirical analysis. The regulatory legal acts of the federal and, to a greater extent, regional levels were analyzed. It was shown that, on the basis of legal provisions, government bodies take necessary and possible organizational and managerial measures to ensure the safety of cities. As a result of the study, shortcomings and gaps in legal regulation that have a direct impact on the effectiveness of law enforcement activities of government bodies to ensure the safety of cities were identified, and measures aimed at its improvement were proposed. Results. The author concluded that urban security depends on the legal status of the city and its various parameters: geographical and political location, size of the territory, prospects for development or degradation, primary purpose or multifunctionality, population density, infrastructure development, etc. Taking into account the ongoing processes of urbanization and suburbanization, it can be argued that the problems of ensuring urban security remain relevant and will affect regional and interregional security, and, therefore, their solution at this level of governance is in demand and necessary.
