Összefoglalás

In developed countries, the growing danger of attacks against information is one of the major problems of the present age, especially because by now, the Internet has become wide-spread almost everywhere from the civil sphere of the world economy up to the administrations. Illegal offence against any information system can turn out to be critical, be it either bank, financial system, telecommunication, traffic, energy provisions or any military or other defence institutions. Furthermore, a possible attack can damage the state infrastructure seriously. Therefore, the main aim of this article is to introduce the different kinds of computer criminals and their devices as well as map the illegal invasion possibilities and show some modes of prevention.
