SECURE MULTILEVEL VIRTUAL COMPUTER SYSTEMS

摘要

In order to securely process data at varying levels of sensitivity, the users and data of the various levels are, at present, physically isolated from those at other levels. This paper presents an approach to insuring the isolation of these levels through the use of logical controls present in a virtual computer system (VCS). In addition, possible uses of a secure multilevel VCS are suggested and parallels are drawn with secure computer system development that would aid in the certification of the VCS security controls.
