User control in a multi-access system
University Mathematical Laboratory, Corn Exchange Street, Cambridge, UK
Administrative controls in an operating system must involve decisions about user status and permitted activity. The mechanisms are traditionally ad hoc and reflect the multitude of curious relationships which usually exist in any organised society. It is also usual to find them distributed through the software complex. This paper suggests a centralised and uniform approach in which a common notation is used to describe all conditions governing status and privileged activity.
