And this circumstance does very difficult counteraction to this threat. According to the author, investigators of a problem need to combine efforts and to develop the uniform coordinated definition of this phenomenon in order that it was possible to state him in the legislation subsequently and to develop rules of the game in information space. After the expert community will come to consensus concerning definition of concept of information warfare, according to the author, Russia needs to initiate at the international level discussion on this matter, and then to promote emergence of concept of information warfare in international law. As soon as this concept is registered there, the countries will agree about rules of the game in an information space. Assistance to fixing in international law of accurately outlined legal definitions and standards of behavior in information space - one of the principles of the asymmetric response to external influence of stronger subjects of information antagonism. However the asymmetric answer - not the only thing that it would be possible to oppose to the existing information threats.
