Abstract :
Currently, risk assessment has been an effective technology of protecting network information system. In order to achieve more accurate result, a new assessment approach is presented in this paper. Our approach introduces the idea of network node correlation (NNC), and based on NNC, we give the conception and characteristic of risk propagation. Also, we design a quantitative taxonomy of network node, and describe the assessment process. Compared with other works, our approach more truly reflects the existence of the correlative risk.
