Research On Anomaly Detection Technology Of Network System Based On Service Oriented Architecture

With the development of science and technology,computer network technology is developing rapidly.Service oriented architecture has been applied to people's life and production.It has the advantages of easier maintenance,higher availability and better flexibility,which is the foundation of the market in recent years.With the concept,standards and technology of mature,many domestic and foreign enterprises,units,organizations are beginning to use SOA related technologies and some products,It marks the SOA has a broad market applications and gradually moving towards maturity.Service Web as the best way to achieve SOA is also favored by many parties,which has a broad space for development in the future of technology.The emergence of SOA architecture brings many conveniences to people's life.The security of the network system is also followed.Traditional firewall defense technology is relatively passive,in the face of the growing changes in the means of attack,there are many loopholes.It is not able to provide security for the network system under the SOA architecture in time,which is a huge challenge to the security of the network system under the SOA architecture.In this paper,the security of network system based on service oriented architecture is studied.Based on the analysis of the security and vulnerability of the SOA architecture,the method of detecting the abnormal behavior of the threat network system is proposed.The method of conditional entropy anomaly detection based on SOA architecture for distributed denial of service attack is improved.Using the SOA typical application system to detect the abnormal behavior detection technology of different attack methods,the different characteristics are chosen as the basis for distinguishing the normal behavior and abnormal behavior.
