A Study on the Government's Countermeasures Against Cyber Attacks

Abstract

The government of Republic of Korea has established and implemented comprehensive countermeasures whenever cyber attacks occur. However, the countermeasures up to now are limited to short-term measures focused on resolving individual issues. The purpose of this study is to suggest implications for the direction of the government's countermeasures against cyber threats with a focus on the National Cybersecurity Strategy. To this end, this study compares and analyzes the changes in Korea's cybersecurity measures that have been developed as the National Cybersecurity Measures, National Cybersecurity Posture Reinforcement Measures, and the National Cybersecurity Strategy. Next, in order to suggest implications for domestic cybersecurity measures, the directions and contents of the National Cyber Strategy of U.S. were compared. As a result, the U.S. has been aggressively considering the preemptive and retaliatory attacks against cyber threats, while Korea's strategy has been relatively defensive. The national cybersecurity strategy that defends against the recent quantitative and qualitative changes in cyber attacks also needs to prepare stronger countermeasures than before. In this context, the direction of U.S. cybersecurity strategy could be an implication.
