Abstract

Over the years, the lack of a unified information technology planning and management, information silos has restricted the development of the information technology industry, the most important issue, especially in the field of military information, fragmented information technology formed the major units of the chimney effect. To solve the problem of information silos, application integration studies emerged. But the implementation of the traditional application integration solution very difficult, but the role is very limited, and based on SOA (Service Oriented Architecture) approach can achieve a good application integration of heterogeneous systems. SOA is based on years of international large-scale information systems software products and an important support technology research and development, but also the military build information infrastructure, development and utilization of information resources to promote effective method. But SOA application security problems delayed the SOA implementation process. Special environment for SOA SOA security defense raised an important issue, since changes in the architecture, traditional security mechanisms have been unable to meet the security needs of SOA applications, which gives an SOA-based security presents new challenges. So how does not affect the loosely coupled SOA, highly scalable design based on the advantages of SOA-based security model to meet the security needs of SOA applications, SOA applications is the study of problems to be solved. In this paper, in-depth study of the SOA security specifications, based on the SOA application system for the current existence of the security issues, single sign-on problems and access control problems based on the \SOA security service model. The main work includes: (1) SOA security research explores the current situation at home and abroad, points out the SOA in the application of information technology insufficient consideration to security, thus establishing this research and design goals. (2) analysis of the current SOA-based information system security requirements, design abstract SOA security reference model, specification-based security framework based on Web services and SOA security services implementation model. Security Reference Model to SOA environment different levels of the different security issues and associated solutions modeled as a three-dimensional reference model that can be used to guide and evaluate SOA security solution design. (3) Detailed design of the security services implementation model core services and key features. Describes the overall framework of security service system design methodology and implementation process of the security services, and services through a combination of interactive processes explains how to implement single sign-on and policy-based authorization. (4) using the latest technology to achieve the security service model designed in this paper, the realization of a prototype system tested the security service system to achieve results. Test results show that the proposed model design and implementation of security services to meet loosely coupled, highly scalable SOA environment security requirements, a variety of SOA security solution design, implementation and deployment of a strong reference value.
