Modeling Support for Confidentiality and Integrity of Object Flows in Activity Models

Description

While the demand for an integrated modeling support of business processes and corresponding security properties has been repeatedly identified in research and practice, standard modeling languages do not provide native language constructs to model process-related security properties. In this paper, we are especially concerned with confidentiality and integrity of object flows. In particular, we present an UML extension called SecureObjectFlows to model confidentiality and integrity of object flows in activity models. Moreover, we discuss the semantics of secure object flows with respect to control nodes and provide a formal definition of the corresponding semantics via the Object Constraint Language (OCL).
