%X In the field of network security,the research of quantitative vulnerability assessment of computer host and network is becoming highlighting.This paper brings forward a method of network-vulnerability quantitative assess- ment,and a corresponding system,based on this method,is established closely after that.In order to obtain the vul- nerability measurement of target host,the possibility of the existence and the exploitability of vulnerability are evalua- ted quantitatively in the system.On the basis of that,by combining with network topology,the dangerous path and critical node of network are analyzed in terms of the refined shortest-path algorithms.Thereby,the administrator can patch the vulnerability with a definite purpose,and which undoubtedly would enhance the general security performance of the network.
