A Comprehensive Security System - the Concepts, Agents and Protocols
Shepherd SJ, Sanders P, Patel A
Computers & Security, vol. 9, pp631-643, 1990

This paper presents an overview of a comprehensive security architecture for use within, and as a value-added enhancement to, the ISO Open System Interconnection model. The system is arranged basically as an application layer service but can allow all of the ISO-recommended security facilities to be provided at any layer of the model. It is suitable as an ?add-on? service to existing arrangements or can be fully integrated into new applications. For large-scale, distributed processing operations, a network of ?security management centres? is suggested, that can help to ensure that system misuse is minimized, and that flexible operations are provided in an efficient manner.
