A Case - Study of Security Policy for Manual and Automated Systems
نویسندگان
چکیده
The assumptions underlying security policy models, such as the Bell-LaPadula model, are usually not explicitly stated. This has led to several common misconceptions about this model and its scope. A comparison of manual and automated systems is used to demonstrate the derivation of the Bell-LaPadula ?property (pronounced star-property) for automated systems and its analog for manual systems. This exercise aids in producing a policy model based on needs and a perspective on the limitations of \classical" security policy models.
