Towards a Model Driven Security for critical infrastructures using OrBAC

In this paper, we use Model Driven Security (MDS) in order to build secure systems. MDS is based on Model Driven Architecture (MDA). In fact, designers are required to only specify system models along with their security requirements; the system architecture is automatically generated from the model. First, we propose a MDS model of the Organization-Based Access Control (OrBAC) model using the MDA modeling framework Eclipse Modeling Framework (EMF). Then, we present a case study in which we choose the Electrical Grid as Critical Infrastructure (CI) to illustrate our approach.
