Analysis and Design of a Computer Security/Recovery System for a Relational Database Management System

摘要

A computer Security/Recovery System (CS/RS) model was designed with the goal of implementing it into a Relational Database Management System. In addition, the relational database was to serve as a pedagogical tool for teaching database management and manipulation techniques as well as security measures and issues. Toward these goals, an extensive literature search and analysis of the current state of the art Computer Security models was required in order to identify current unresolved issues and areas of research. The advantages and disadvantages associated with six computer security models were explored and addressed in this thesis. Then the requirements for a CS/RS model were indentified and defined, and based on certain favorable criteria, one of the computer security models analyzed was selected. Further, only one of the six models had ever been implemented using a relational database and none had ever been implemented using a microcomputer. Consequently, the ability to take one of the existing computer security models and to apply the security concepts used within this model was not an easy task and in some instances was not possible. Finally, the CS/RS model designed did not include the hierarchically ordered military security sensitivity levels. (Author)
