ABSTRACT
When developing a new system or performing major modifications to an existing one, the architecture phase represents the initial steps of defining the functional and physical characteristics of the new system. Security architecture is simply a view of overall system architecture from a security perspective. The security architecture should be established as an integral part of the system architecture. It provides insight into the security services, mechanisms, technologies, and features that can be used to satisfy system security requirements. Interoperability is a typical architecture focus that demonstrates the criticality of developing these inter-view relationships. The operational view describes the nature of each need's information exchange in detail sufficient to determine what specific degree of information-exchange interoperability is required. The framework is a conceptual model that begins to define a documented and coordinated structure for cross-cutting businesses and design developments in the government.
