The Confrontation between the Right to Privacy and National Security against Cyber Terrorism

National security and the attempts for substantiating and protecting it, are of the main tasks in any political system. However, terrorism, as one of the most serious threats to the security of any political system, has evolved from its traditional form with the help of technological advances in recent decades and found a new place in cyberspace that comparing to its previous form, it becomes even more advanced and dangerous. In fact, terrorism, in its new place and form, has increasingly put the security of countries at risk. National security may be protected by such measures as punishment of the terrorists and/or implementation of crime prevention policies, but, measures taken for protecting security may conflict with the right to privacy in some cases. Thus, such conflict has raised a question regarding which one is prior to the other and therefore, should be put first. This article seeks to answer such question.
