Secure Database Management Study.

This document reports the findings of a study of alternative system architectures for secure database management systems. System requirements are stated and the relation to operating system security is discussed. Security kernels, their history as well as their advantages and problems, are described. Additional security requirements for database systems are introduced and some models and experimental systems are reviewed, representing non-architectural and architectural approaches to non-secure and secure database systems. Conclusions and evaluations are made throughout. It is also suggested that military planners and system designers re-evaluate their traditional approaches to security policy, in order to take advantage of emerging technology. Broad-based recommendations are then made as a baseline for determining appropriate research directions in the area of data security. Author
