Application of grey relation in analyzing network security events

The mass of network security data is automatically and intelligently related and analyzed, which reveals the logic relations and the attack intention hidden behind the events. Sorting the attacks on various severities, a variety of fast and intuitive analysis report is generated. It can comprehensively monitor network status, effectively guide network security management, effective prevention, block or reduce security threats, which is a very valuable and necessary means to network security. Through grey relation, the multidimensional reference space data rows, the comparing rows of main characteristic indexes and the factor indexes have been set up. The relation coefficients and degree are computed and the quantity of dynamic trend of network security events is analyzed. Through the expression of correlation coefficient and case study, it can be concluded that the grey relation is effective to discuss and analyze the network security events predominantly.
