Quantitative Analysis of Network Security Events Based Grey Relation

Aiming to solve the problem of network security evaluation index, the data extracted from net flow are analyzed. And the data are aggregated by several relational dimensions. Using the method of grey relation advantage analysis, the grey relation values of network security events and the characters of the data are calculated. The pivot characters representing the events were decided. Then a set of network security evaluation indices are proposed. The experiment results show that the indices can reflect the network situation efficiently.
