摘要：Nowadays, the vast majority of the threats to our security is related to information security, resulting in a significant transformation of national security systems. One such threat is disinformation, which is increasingly being used intentionally. The study examines certain impacts of disinformation on national security as a system, on the example of the COVID-19 pandemic. Therefore, the study explores some processes visible at the international level and reviews some external problems in connection with national security. Research methods and techniques implemented in the research process itself are primarily based on a critical analysis of the literature and the analysis and synthesis of published research results. The main findings show that the phenomenon of disinformation, which intensifies in crisis situations (e.g. related to the outbreak of a pandemic) contributes to the destabilization of public mood, hinders the functioning of the basic organs of the state and, consequently, increases the negative effects of crisis events. Secondly, the disinformation used during the COVID-19 pandemic has exacerbated its effects, causing damage on an unprecedented scale. The analyses show that the fight against disinformation must be based on the assumption that the security of the state depends primarily on the information awareness of each citizen. Social awareness is built through effective education aimed at raising basic medical knowledge. Disinformation has serious consequences for modern countries as it creates a new threat to their national security in peacetime.
