Abstract
Access control policies [ACPs] regulate the access to data and resources in information systems. These ACPs are framed from the functional requirements and the Organizational security & privacy policies. It was found to be beneficial, when the ACPs are included in the early phases of the software development leading to secure development of information systems. Many approaches are available for including the ACPs in requirements and design phase. They relied on UML artifacts, Aspects and also Feature for this purpose. But the earlier modeling approaches are limited in expressing the evolving ACPs due to organizational policy changes and business process modifications. In this paper, we analyze, whether “Feature”- defined as an increment in program functionality can be used as a modeling entity to represent the Evolving Access control requirements. We discuss the two prominent approaches that use Feature in modeling ACPs. Also we have a comparative analysis to find the suitability of Features in the context of changing ACPs. We conclude with our findings and provide directions for further research..
