A View-based Approach for Service-Oriented Security Architecture Specification

Developing secure software is still a software engineering challenge because of the complexity of software security. Yet integrating security engineering and software engineering is increasingly important, especially for serviceoriented applications, as they are exposed to new security challenges due to their open nature. Current security engineering approaches do not consider existing security architectures, leading to redundant development of security artifacts. Further, present security architecture approaches do not provide relevant information to a security engineering process. Using a service-oriented and security architecturecentric approach for security engineering supports the development of secure service-oriented applications, as existing security solutions can be reused. In this paper a model for service-oriented security architectures is presented, which provides apt information to different consumers, such as security engineering processes and business services, in the form of views to assist the consumers security goals. The architecture model is exemplified by specifying different views of a web service-based security architecture.
