Comparison and Evaluation of Information Security Models for Access Control

This paper presents an approach to various forms of security and different access levels required in an information system by analyzing mathematical models that can be applied to this field. By describing their structural characteristics and how they find implementation in the study of information security, this paper underlines the necessity, means and effectiveness of information security modeling. The conclusions of this paper highlight the importance of a well-defined security risk management and how achieving this goal provides an opening for future research.
