A methodological approach for hypermedia security modeling

In hypermedia systems security is becoming a key requirement to preserve both confidentiality and integrity. Although some authorization models for hypermedia have been proposed, what is needed is to integrate security modeling into the whole development process, so that designers count on methods to specify all the features of their hypermedia systems, including navigation capabilities, interactivity, multimedia features as well as security. In this paper, we describe how security modeling is approached in a methodology for hypermedia systems, called Ariadne, that offers a number of conceptual and platform-independent tools to specify the features of any hyperdocument in an integrated and progressive way.
