Role of Libraries in Ensuring Information Security

The purpose of the article is to analyse the forms, methods, and means of library work for resistance in the information war. The research methodology is based on the application of general scientific and special methods of cognition, in particular, selection, analysis, synthesis, and systematisation of materials. The novelty of this study lies in the comprehensive study of professional strategies and methods of successful confrontation in the information war in libraries. Unreliable information is currently used as a weapon in political confrontation – information wars at the level of states and among political parties, as well as unfair rivalry – in the economy. Having received false and distorted information, one can make incorrect conclusions, which in the future lead to wrong actions or expose them to danger. That is why information security is so important for every person, and media literacy skills will help to filter information and use it rationally. Conclusions. The article analyses the concept of "information war"; technologies for preventing the spread of false information are described; information on improving media literacy of the population, in particular, and library workers is provided. The issue of restoring Ukrainian culture, ensuring information security on the territory of the state should be taken into account by the management of libraries, and the institution should provide maximum guarantees to preserve the basic network of libraries and their maximum activity in every part of the country. It should be emphasised that in the modern information-active environment, libraries are indeed one of the key elements of the information infrastructure of social activity, as a rule, based on the most effective use of modern electronic technologies. Therefore, their work consists in supporting the effective dissemination of information in the most popular mass media.
