On the Contextual Security Architecture Layer, Business Users provide the business requirements that must be met by the architecture. At the Conceptual Security Architecture layer, an architect provides the overall context by which the business requirements of the organization are to be met. On the Logical Security Architecture layer, the Designers provide a systems engineering model which views the business as a system and delineates it in terms of a system of systems through various sub-systems.

On the Component Security Architecture layer, the tradesmen work on specifications provided by the builder and work with specialist products and system components which together, build what was expected by the builder.
