In the conditions of martial law in Ukraine and the development of globalization processes, the Ukrainian information resource is a subject to the development strategy of the nation or state, which is implemented through the appropriate state information policy. It should cover all areas of life in the development process of a new information society. Its basis can only be a national ideology, which should become the core of information policy and fill the entire information space with meaningful content. Moreover, regardless of the processes of informatization, politics remains, first of all, a value-symbolic sphere. The absence of a nationwide ideological project leads to the formation of an information and communication vacuum, the consequences of which can be complex socio-psychological crises in the society. Ideology as a set of certain ideas, values and beliefs is both the basis of the formation of information policy and the most important element of mass political communications. Thus, the formation of the information political space, the role and place of the state in this process, as well as the importance of the value-ideological component in its information policy reflects high scientific and practical interest and requires constitutional support. The use of hybrid warfare technologies by the Russian Federation against Ukraine has turned the information sphere into a key arena of counterinsurgency. It is against Ukraine the Russian Federation uses the latest information technologies to influence the consciousness of citizens, aimed at inciting national and religious enmity, promoting an aggressive war, changing the constitutional order by force or violating the sovereignty and territorial integrity of Ukraine. It also undermines information sovereignty with the help of disinformation, fakes, cyber attacks with interference in the work of state bodies and critical infrastructure of Ukraine, and other risks that pose a general challenge to the state security of Ukraine. And therefore, it gives reason to thoroughly analyze and provide recommendations in terms of the conceptual apparatus in the field of information sovereignty of Ukraine in the modern period, which is also confirmed by the relevance of this scientific study. The purpose of the article is to analyze the conceptual apparatus in the field of «information sovereignty of Ukraine» in the modern period and to provide the author's proposals for its improvement. Thus, in order to carry out further research and for the purpose of streamlining and unifying the terminology in the analyzed area, it is proposed to understand the essence of the concept of «information sovereignty» to supplement it with the word «technological» and define it in the ab. 10th century 1 of the Law of Ukraine «On the National Informatization Program» as follows: «information and technological sovereignty of Ukraine» is the state's ability to organize, control and regulate information flows with the help of domestic innovative technologies (data registers and own information resources) from outside and inside the state to form the infrastructure of the Ukrainian information space, in order to observe the constitutional rights and freedoms of a person and a citizen of Ukraine, as well as to realize the right to truthful information (primary source), by means of interaction with the world information space to guarantee the national security of the state. Further scientific research will be devoted to problematic issues of legal regulation of Ukraine's information technology sovereignty and protection of Ukraine’s interests in the global information space and international information relations. Keywords: conceptual apparatus, cyberspace, information sovereignty, innovative technologies.
