Abstract:

The aim of the study is to measure the cyber security performances of G7 countries over the 2020 Global Cyber Security Index (GCSI) component values with the ENTROPY-based MABAC method and to show that GCSI can be explained with the ENTROPY-based MABAC method. According to the findings, the cyber security performance values of the countries are listed as USA, England, Germany, France, Canada, Japan and Italy. In the research, it has been determined that there are significant differences with other countries in terms of the high cyber security performance of the USA and the UK. Therefore, it has been concluded that Germany, France, Canada, Japan and Italy should increase their cyber security performances in order for countries to be in harmony on cyber security. The relationships between the countries' GCSI and some ENTROPI-based multi-criteria decision-making methods (ÇKKV) (ARAS, BTA, COPRAS, EDAS, ROV, WASPAS, TOPSIS, Gray Relational Analysis) were measured. According to the results, it was determined that the GCSI values of the countries were most correlated with the values measured by the ENTROPY-based MABAC method. Accordingly, it has been found that GCSI can be explained the most by the ENTROPI-based MABAC method among the mentioned MCDM methods
