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).
FIPS 201 under Architecture [version unknown]
complying with the principles that drive the system design; i.e., guidelines on the placement and implementation of specific security services within various distributed computing environments.
NIST SP 800-27 Rev. A [Withdrawn]
Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution.
NIST SP 800-160 under architecture (system) [Superseded]
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.
