Security requirement with a UML 2.0 profile

Business processes are important for companies because they allow us to obtain an advanced marketplace position, and then, these enterprises can optimize and assure the quality of their products and services. Moreover, business processes are important for software developers, because they can capture from them the necessary requirements for software design and creation. At the same time, organizations have been opened and this implies more vulnerability. In spite of all these facts, security is an aspect that has been scarcely dealt with in the business process modeling. In this paper, we summarize our UML 2.0 profile for secure business process modeling through activity diagrams, and we apply this approach to a typical health-care business process.
