The settlement of IT(Infor-mation Technology) living zone has led to high reliance on information communication, which poses a possible threat to the infringement of information communication. In Korea, however, cyber attacks by North Korea have been found to be the largest among the infringements, and the amount of damage is said to be more than 1 trillion won. Recently, cyber terror attacks by North Korea have threatened the information networks of private companies as well as major systems of the nation with increasing frequencies. However, the Korean government has limited capabilities to cope with such treats in the cyberspace in terms of manpower, time, and cost.
