Providing a Security Model Based on Service Oriented Architecture in Electronic Banking

With the increasing advances in IT world and the use of distributed systems, complexity and performance of applications have also changed. Banks require proper cooperation and integration among organizational systems to provide effective and correct services. On the other hand, they contain diverse and heterogeneous infrastructures, applications and systems. Cooperation and integration among these systems require interactions and information sharing among the users. The service-oriented architecture is the latest generation of information systems' architecture and has become quickly inclusive in recent years. One of the important features of this architecture is the numerous users of different subsystems and their communication and cooperation in activities. In this architecture, resources and services are often provided in sharing for different users. But, such features in service oriented architecture have brought about some challenges to the technology, one of which is 'the security'. The need for a security model in service-oriented architecture seems essential due to the distributed nature of the architecture, its reusability and accessibility. In this model, security requirements and standards for different layers are studied.
