The article’s primary goal is to assess the Russian-led disinformation operations and to examine NATO’s counterstrategies within the broader context of information warfare. By understanding motivations, mechanisms and consequences of Russian Federation’s use of propaganda and disinformation, one gains a better ability to counteract such practices, bolsters the psychological resilience of a society, and becomes able to establish a sustainable regional information security model. In the context of this work, we understand the existing model as a set of technological, organisational, political, and sustainability measures that create the prerequisites for the states of the region to achieve a high level of information space security.
