Abstract. Information safety as one of the essential elements of the European Union’s safety strategy. The following article aims at answering the question of how the skillful use of information affects the system of state security, or even international organizations, including a special type of organization of transnational character, namely the European Union. It will be important to identify new threats to international security generated in the XXI century, and which are directly related to the information – means of acquiring, collecting, processing, conservation and most importantly – effective management and exploitation. With these elements raises the problem of misinformation – manipulation of information, misleading both the public and potential adversary (this applies equally to actions at governmental level and the activity of media). New technology gives unknown possibilities of extremely smooth and efficient flow of information, which also involves nontraditional threats (cyber terrorism and a new dimension of information war).
