Model Driven Architecture is an approach to increase the quality of complex software systems by creating high-level system models and automatically generating system architectures and components out of these models. We show how this paradigm can be applied to what we call Model Driven Security for inter-organizational workflows in e-government. Our focus is on the realization of security-critical inter-organizational workflows in the context of Web services, Web service orchestration and Web service choreography. Security requirements are specified at an abstract level using UML diagrams. Out of this specification security relevant artifacts are generated for a target reference architecture based on upcoming Web service security standards. Additionally, we show how participants of a choreography use model dependencies to map the choreography specifications to interfaces for their local workflows.

Business Process Execution

Web services based on a service-oriented architecture framework provide a suitable technical foundation for business process management and integration. A business process can be composed of a set of Web services that belong to different companies and interact with each other by sending messages. Web service orchestration languages are defined by standard organizations to describe business processes composed of Web services. A business process can fail for many reasons, such as faulty Web services or mismatching messages. It is important to find out which Web services are responsible for a failed business process because we could penalize these Web services and exclude them from the business process in the future. In this paper, we propose a model-based approach to diagnose the faults in a Web service-composed business process. We convert a Web service orchestration language, more specifically BPEL4WS, into synchronized automata, so that we have a formal description of the topology and variable dependency of the business process. After an exception is thrown, the diagnoser can calculate the business process execution trajectory based on the formal model and the observed evolution of the business process. The faulty Web services are deduced from the variable dependency on the execution trajectory. We demonstrate our diagnosis technique with an example.
