The paper presents an original approach to the issue of maritime security modeling, which is commonly treated as one of the many categories that dominate in the theory and practice of national security. Elements of the theory of security and its basic definitions are initially outlined. There was also a discussion on the endless problem of severability / identity of national security and state security. For the eponymous maritime security, the basic types of threats causing its destruction have been specified. Particular attention was paid to the multidimensionality of maritime security and the related typological divisions and legal and international consequences. The underlying rationale for considering maritime safety as a ambiguous concept with global and transboundary relevance has been outlined. It does not refer to any specific entity whose interests may be threatened to some extent, but to the entire marine environment, which is a category common to all participants in international life. It defines the general conditions for the use of sea space and areas by various national, international, commercial, public and non-public entities - in accordance with certain rules respecting the security universe. The conclusion indicates the main entities and administrative bodies shaping the required safety standards in the national and international dimension. The main thesis of the work states that maritime security, as a generic category of national security, has a significant impact on many types of subject security, and thus on the general level of national security of each coastal state. In the era of globalization, maritime security, along with economic, social, economic, information, energy and many other security, is one of the key components of national security and state security. The rank and importance of maritime security, along with the expansion of human civilization, will be increasingly subjected to the pressure of various economic, social, political and environmental factors. Precise anticipation and elimination of key challenges and threat factors may be the main criterion for stabilizing maritime security, which is so important in shaping contemporary national and international security.
