Disinformation is defined in the context of state security and as a tool used by state agencies to achieve the goals set out by political authorities. The analysis included publicly available reports of the agencies responsible for state security, both Polish and those of other members of the North Atlantic Treaty Organisation (NATO). The research question posed in the article is: are the same methods of disinformation used against Poland and other NATO member states and what issues do they concern? The article primarily uses the method of analysis and comparative analysis of the above-mentioned reports and information materials from security agencies, both intelligence and counterintelligence. The mechanisms of counteracting and combating disinformation are exposed and recommendations for combating disinformation are made.
