The paper aims to analyse how information warfare can be conducted in cyberspace and to look at this issue from the perspective of Central and Eastern European Countries. It argues that this form of hostile actions will be increasingly utilized in the region. The main assumption, following Alvin Toffler’s theory, is that “information” – as an increasingly important element of modern societies and as their strategic resource – also serves as a significant tool of modern conflicts. Since information is nowadays strongly related to new technologies, mainly the aspects connected to cybersecurity are analysed. The article looks closer at different aspects of cyberthreats and explains their possible consequences. It may serve as good material for further research and recommendations on countermeasures that may increase security in Europe.
