Combating terrorism information has become not only an important matter of policy, but also, and perhaps above all, the problem of economic nature. Cyberterrorist can also adjust their activities in order to maximize the positive outcome for themselves. In addition, cyberterrorism does not require physical training or high security logistics. There also requires travel. Cyberterrorism is not a separate or specific type of terrorism because of ideology. It serves exactly the same purpose as bombings, kidnapping or hostage taking. There are only a form − using computer hardware and software. Cyberattacks do not pose a risk of death or physical injury, reduce the need for so risking life − attacks on the network do not require for suicide attacks. To carry out such an attack, you do not need to have virtually no skill − you can rent a cracker who broke security (often without realizing the consequences of his actions) money will carry out a terrorist attack. Past examples of cyber crimes show how a large number of people may be affected by the consequences of such action; this is due to the global nature of computerization. Thus one of the essential objectives of terrorists − mediality attack − is huge. A separate issue is the use of the Internet and computers by terrorists for purposes other than direct attacks. Computer systems are a great collection and exchange of information and communication. They provide anonymity, allow coding or hiding information. Transfers can be hidden do not raise suspicions text files or graphics.
