Network security situation means the safe running-state of the entire network,and the research on network security situation is one of the hot topics in security field.In order to accurately grasp a network system's security situation,designs a hierarchical network security situation evaluation method based on the grey theory.This method relates attack factors in the network by utilizing the grey incidence analysis;obtains the corresponding situation information by using both of the weightiness given by expert system and the statistical technology on the three-layer of services,hosts and networks.The result of simulation experiment based on the Honeynet Data Set illustrates that the whole network security situation can be efficiently and exactly obtained by this method.
