Net Safety Evaluation Index Based on Grey Advantage Analysis Method

Aiming to solve the problem of net safety evaluation index, the data extracted from NetFlow 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 safety affairs and the characters of the data are calculated. The pivot characters representing the affairs were decided. Then a set of network safety evaluation indices are proposed. The experiment results show that the indices can reflect the network situation efficiently.
