A highly structured specification of an acceptable approach within a framework for solving a specific problem. An architecture contains descriptions of all the components of a selected, acceptable solution while allowing certain details of specific components to be variable to satisfy related constraints (e.g., costs, local environment, user acceptability).

  A set of related physical and logical representations (i.e., views) of a system or a solution. The architecture conveys information about system/solution elements, interconnections, relationships, and behavior at different levels of abstractions and with different scopes. Refer to security architecture.
