Service-oriented Network Security Situation Assessment Method In Multi-layer Union

With the continuous development of the Internet technology, Web services ine-commerce, e-government, e-business processes and other applications are widely used.Network services have led to the increasing scale of Internet, a variety of network applicationshave produced constantly. Web services are increasingly important. Protection for networkservices or network protocols is especially important for network security.In the field of network security, service-oriented network security situation assessment isof great significance, which can ensure the normal and safe of network. Currently, thetechnique of service-oriented network security situation assessment has achieved some of theresearch results, but it is lack of research in the correctness and accuracy.Based on the thinking of service-oriented, this article researches and practices themethod of service-oriented multi-layer union network security situation assessment from theperspective of multi-layer union assessment. This article analyzes the features of networklayers’ protocol and the corresponding indicators, and then establishes the network securitysituation’s index system for the HTTP protocol of network application layer. Combining withthe existing situation indicators of transport layer and network layer, this article establishes amulti-layer union index system of network, and then proposes a method of multi-layer unionsituation assessment, which improves the correctness and accuracy rate of assessmentabsolutely. This method can assess the entire network’s security situation. Finally, a system ofservice-oriented multi-layer union network security situation assessment is designed andrealized, which improves the correctness and accuracy of assessment absolutely. The systemcan analyze data of network security situation from each layer of the network, monitor theoperation and services of network real-time, and thereby achieve the purpose of assessing thenetwork’s overall security situation.
