An integrated approach for identity and access management in a SOA context
In this paper, we present an approach for identity and access management (IAM) in the context of (cross-organizational) serviceoriented architectures (SOA). In particular, we defined a domainspecific language (DSL) for role-based access control (RBAC) that allows for the definition of IAM policies for SOAs. For the application in a SOA context, our DSL environment automatically produces WS-BPEL (Business Process Execution Language for Web services) specifications from the RBAC models defined in our DSL. We use the WS-BPEL extension mechanism to annotate parts of the process definition with directives concerning the IAM policies. At deployment time, the WS-BPEL process is instrumented with special activities which are executed at runtime to ensure its compliance to the IAM policies. The algorithm that produces extended WS-BPEL specifications from DSL models is described in detail. Thereby, policies defined via our DSL are automatically mapped to the implementation level of a SO...
