Energy Security has been factor of great importance to national security, economy, society and all other areas. However, it has been in the lack of situation where there is no leading method to measure energy security nor to compare among countries until now. In the research, objective index to assess energy security has been developed and compared among the level of countries in terms of energy importing countries' perspective. Based on the suggested index, comparison for the energy security level has been explained. The implication of the research is that in terms of energy importing perspectives, method to appraise energy security and according to this, energy security rate by each countries with respect to LNG. This method is doubtlessly applicable to comparison of security rate from other resources and fluctuation of energy security by reflecting other factors. Also, discussion about how increased autonomy of resources can impact Korean energy security with regard to recent international energy development. As a consequence, it has revealed that enhanced authority of resources evokes ascendancy of energy security in a positive way.

Natural gas is globally emerging as an important energy source for environmental, political and regional reasons. In Korea, natural gas imported from oversea natural gas resources as a LNG, it is increased for an applications as a fuel and feedstock which replace the coal and nuclear energy. Because it is relied on the import market in Korea, it is very important to analyze the security for supply. Therefore, this study suggested a method for reducing supply risk and for providing stable supply and demand through risk analysis of Korea's import structure. In order to reduce the supply risk, the concentration of importing countries should be lowered and it is necessary to lower the proportion of countries with relatively low GSSI and increase the imports from Russia. Finally increasing the number of importing countries or maintaining friendly relations with countries where the supply is stable could give us the positive impact in terms of total GSSI.
