Data Integrity Limitations in Highly Secure Systems

Abstract

We discuss a class of computer/network architectures that supports multilevel security while utilizing commercial-off-the-shelf (COTS) workstations and COTS productivity software applications. We show that a property of these architectures is that, while supporting multilevel confidentiality policies, they do not generally support partially ordered integrity policies: specifically, these architectures do not support the maintenance of data that is higher in integrity than the integrity level of the COTS components.
