The main goal of the article is to consider whether there are sufficient premises to perceive the issue of foreign electoral intervention as a problem of international security (in the meaning of the concept of political dimension of security) in relation to contemporary political realities. The problem is analyzed on the basis of circumstances related to the activity of Russian entities accompanying the referendum on the membership of the United Kingdom in the European Union (2016) as well as the presidential elections in the US (2016) and France (2017). The secondary objective of the paper is to present the spectrum of means and methods used to conduct activity aimed at attempting to influence the elections’ result, with particular emphasis on ICT and using the cyberspace (including social media) as well as an attempt to define key concepts emerging in this context in the public space.
