Designing Security System Using Aspect Model

Complexity and high number of cause-effect relationships in information systems aggravates observing and managing information security issues. What is missing here is the method of conceptual modeling that will be used for describing and visualizing features and interdependence of security system elements. Up to now there have been some attempts to solve this problem, but the existing solution does not satisfy completely. What is suggested in this paper is a graphic technique of conceptual modeling based on the aspect model following the example of the application generator script model. Such modeling of a security system is used in solving the problem of multiple inheritances of security attributes and it makes the analysis of complex hierarchy among the security objects possible to be observed from different aspects. In this paper we have defined some basic graphic elements of aspect model used to show information resources and their relationships and attributes as well as protection measures, and the way of forming models is shown on the examples.
