The issues of the paper are given a concise overview, of the current state of capabilities of "small states" for informational action. In the context of "small states" specific abilities necessary for informational action are described and the basic challenges of their development analyzed. Also, a brief critical review of the theoretical and doctrinal bases of the information activity of the institutions of the Republic of Serbia is given. The emphasis in the description of capabilities is on those that are carried out by informative and perceptive methods (propaganda, managing the perception of the opponent, disinformation, psychological operations, deception), about those that are carried out by informational and technical means (by attacking critical objects of the national infrastructure, cyber-attacks), precisely because of their dominant base on knowledge, good organization and the use of easily available resources and means, and not on technical-technological supremacy, large material-financial investments and expensive technology, unattainable for "small states".
