Esb System Security Research And Applications

Enterprise Service Bus (ESB) plays a intermediate role in intelligent integration and management of services in service-oriented architecture (SOA), is the current mainstream middleware technology of enterprise system architecture. Compared with the traditional ESB system, ESB system in cloud computing environment can make the quality of middleware services improved, the deployment of system architecture more flexible, and the system integration costs and expenses reduced. However, it brings new security problems when enterprise architecture is moved to the clouds. Therefore, the ESB system security research, particularly the security research of ESB system in cloud has important significance both in theoretical and practical.Firstly, this thesis analyzes the principle and architecture of the ESB. Several aspects including scalability, message mechanism, applicable scene and performance of the existing mainstream ESB products are summarized and analyzed, and the existing safety critical of the ESB system is also summarized in this thesis. Secondly, on the basis of the security issues to ESB system in cloud computing environment, a cloud-based security ESB architecture is proposed, and corresponding security solutions for six areas of security issues including data access, data transmission, key management, virtualization, data leakage and data storage have been given in this thesis. Therefore, a depth defense system is achived by using the layered architecture and setting multiple security mechanisms for each security issues. Finally, this thesis describes the design and realization of relationship management system between corporation and customer with security ESB architecture. Furthermore, it gives a detailed description of implementation of security mechanism and designs about the modules relating to the security strategy.
