摘要：New information technologies are unavoidable factor in modern world as they are changing it both in technological and in communication aspect. Unfortunately, despite the opening of new possibilities, both aspects of changes have brought about vulnerabilities which cannot be ignored. These vulnerabilities directly affect security state in the systems where ICT is becoming dominant information and communication platform. Therefore, critical infrastructure security as the key element of national security today is to a great extent determined by ICT security as its component. Thus, ICT vulnerabilities are directly spread to critical infrastructure in which they are built and whose abuse is only a matter of time. It is not only terrorists who should be regarded as a threat when thinking about critical infrastructure security, but also organized and commercial crime, competitive companies, various hackers, even all those who due to different social and economic reason live on the margins of modern society. Of course, nobody among the mentioned is immune to committing a terrorist act so as preventive measure all of them should be spotted and prevented in accordance with security estimates.
