architectural solution
163540·updated Aug 30, 2026A design-level response to a security, privacy, or compliance requirement — one that resolves the requirement through structural choices about how components, systems, or services are arranged, separated, or interconnected rather than through policy alone or through a single point-in-time control. In NIST usage, an architectural solution names and describes a particular deployment configuration — such as a specific encryption placement strategy — and then maps the key-management or other security challenges that follow from that structural choice. In policy contexts (such as the passage you quoted), organizations or regulators mandate specific architectural solutions when a security property — for example, mandatory access control or network isolation — cannot be reliably achieved through configurable settings and must instead be built in at the design level.

A web lookup ran when this term was proposed
A design-level configuration of system components, mechanisms, and their relationships selected and mandated to satisfy a specific security, privacy, or compliance requirement that cannot be reliably met through policy or operational controls alone. In authoritative NIST usage, distinct architectural solutions represent structurally different ways to accomplish the same security objective — for example, whole-database encryption versus client-side field-level encryption — each carrying different key-management and trust implications. In the field, the expression is used when an organization or standard requires that a particular structural approach be prescribed rather than leaving implementers free to choose any mechanism; access enforcement mechanisms, for instance, may be required at both the system level and the application or service level to provide the necessary information security and privacy guarantees. The term operates at the level of system or solution architecture — spanning topology, component selection, and data-flow design — rather than at the level of a single control setting or configuration parameter.
Advisory only. A term this product ships is defined by an authority document, not by a search result.
