Abstract

This study is to block the activity of cyber security threat forces go on and strengthen security in an effective response. Recently, the forces that threaten the security are a threat to security by strengthening their activities in the cyberspace that it is not easy to get caught without physical limitations. Those who threaten the security in the cyberspace have threatened the security through intensive way to attack the weaker areas while utilizing the characteristic of the cyberspace skillfully. The main security threats acts are cyber attack against major national facilities, exchanging critical information and commanding an order through the channels, and psychological warfare activities using various propaganda media of North Korea. In order to prevent cyber threats, the attacks against major facilities in cyberspace, I propose a blocking method in complex forms that can block an offensive epicenter and a destination at the same time rather than fragmentary blocking method. Additionally, in order to snatch or block the main usage channel that those who threaten the security used, I suggested that enhancing the existing detection methods, outsourcing detection to external agencies, purchasing, and etc. Lastly, in order to block to contact our people, the system needs to be improved with ongoing monitoring activities which need to be carried out against psychological warfare in cyberspace.
