Paper Abstract:
|
Security and access control, respectively, are often neglected in conceptual design of user interfaces. This paper presents a combination of HCI models and access control specifications to overcome this problem. The work aims at a systematic introduction of security concerns in model-based development of interactive systems. We concentrate so far on the early design steps, i.e. mainly on the specification of task and role hierarchies, and on conflicts that may result while the models are specified. Herewith, security concerns are considered at the stage of early design steps. The focus of this paper is on a tool supporting the integrative specifications of tasks and access control rules. It is shown how the tool assists in structuring the model taking into account model properties defined before. Incorporated functions check consistency violations and support to solve them. Additional support is realized by a view concept that assists the developer interactively in traversing the coherent model. In combination with filtering mechanisms and the possibilities of follow-up queries different views can be generated and altered. Both the automatic assistance in structuring a model and the dynamic view aim at the reduction of modeling complexity and at avoidance of modeling errors. |
