Research on the Aggregation Model of Network Security Situation Awareness Based on Analytic Hierarchy Process

Along with the development and application of computer network, the network security problem has become an urgent task, and the security problem research also becomes an important topic to the network development. The analytic hierarchy process as a powerful method in system science analyzing was introduced into the research of network security situation awareness. The common model of networks security situational awareness architecture is described, and studies the evaluation method relevantly: from security situation numeric computation, the analytic hierarchy process arithmetic is analysis. When a network includes multiple subnets, the network situation of the total network need to be further aggregated. So a new aggregation model and method was proposed.
