Is there a need for new information security models?

摘要

A considerable number of formal information security models have been developed during the last two decades. We present and discuss some of the most widespread ones that have been successfully applied to the traditional, centralised Information Systems of the past. We show the special security needs of modern information systems that are based on the concepts of Open Distributed Processing, the Object-oriented paradigm and multimedia technology. We argue that these Information Systems need new or enhanced information security models in order to address the information security issue effectively and present some efforts towards this goal.
