Reasoning About Security Models

Abstract

A method for evaluating security models is developed and applied to the model of Bell and LaPadula. The method shows the inadequacy of the Bell and LaPadula model, in particular,and the impossibilityof any adequate definitionof a secure system based solely on the notion of a secure state. The implications for the fruitfulnessof seeking a global definition of a secure system and for the state of foundational research in computer security, in general, is discussed.
