National Security in the Era of Information

The unprecedented advancement of the cutting-edged information technology bas made the game we play, the business we conduct and the politics we engage, faster and more complicated with stronger global linkage between events, which adds complexity and reduces predictability. Information revolution has generated fundamental changes in production, distribution, utilization and expansion of information itself. In this sense, information warfare has to be understood as something unprecedented since it would be highly colored by cyber terror on communication network, information hacking and cyber attacks on firewalls. The new paradigm of information warfare has challenged the traditional concept of national security and certainly required states to act upon this fast emergence of new trend. In this, information warfare is defined as the offensive and defensive use of information and information systems to deny, exploit, corrupt, or destroy, an adversary's information, information-based processes, information systems, and computer-based networks while protecting one's own. Such actions are designed to achieve advantages over military or business adversariesInformation warfare is divided by MTR (Military Technical Revolution), RMA (Revolution in Military Affairs) and RSA (Revolution in Security Affairs) in terms of the level of information technology and characteristics. The MTR is simply, by applying information technology to the weapon systems, the development of new weapon system. Thus, the concept of military mission is not fundamentally different from the traditional one. However, the RMA is the realization by the military that information, and information technologies must be considered as a weapon in achieving national objectives via military activity. The RMA requires comprehensive linkage and connectivity of each weapon system that must be consist of on-line network to carry a military mission. The RMA is the highest level in the information warfare which generates the larges scale changes in the concept of military mission, doctrine and national security.There are 7 types of information warfare; Command and Control warfare, Intelligence-based warfare, electronic warfare, psychological warfare, hacker warfare, economic information warfare and cyber warfare. In information warfare, the offence target has varied from states to organizations and individual. The cost of carrying a military mission has become economic. Early warning and damage assessment has become virtually impossible due to the unprecedented increases in cyber-interactions. It has become difficult to manipulate information and the public opinion as access to information is open virtually to everyone. As the concept of war itself has expanded, any place that is accessible has become combat places due to the web of information networks. Gulf War was the first information warfare where the satellite surveillance system and precision-guided weapon were used to carry combat missions. At Yugoslavia, hacker warfare has emerged as a new warfare for the first time in the history of warfare.Under these circumstances of dramatic changes in the concept of warfare, major powers surrounding the Korean peninsula are in the process of constructing measures for information warfare. The United States are the leader in driving for the MTR and the RMA in order to countermeasure any cyber attacks on its information networks. In so doing, the US is developing not only the hardware and software of information warfare but also institutionalizing legal and institutional frameworks for the new century of information warfare. Chain has already constructed information networks that links major cities and military compounds in mainland, and is in the middle of creating anti-virus operation teams to effectively manage cyber terrors on its complicated information networks. Russia, having realized its increasing dependence on the imports of computer hardware as well as software,
