Title Controlling Usage in Business Processes Workflows through Fine-Grained Security Policies
Abstract We propose a language for expressing fine-grained security policies for controlling orchestrated business processes modelled as a BPEL workflow. Our policies are expressed as a process algebra that permits a BPEL activity, denies it or force-terminates it. The outcome is evaluates with compensation contexts. Finally, we give an example of these policies in a distributed map processing scenario such that the policies constrain service interactions in the workflow according to the security requirements of each entity participating in the workflow.
