Each layer answers these six questions at its own level of abstraction. At the contextual layer, for example, the "Assets" column captures "The Business" as a whole—its strategies, reputation, and market position. By the time we reach the component layer, the "Assets" column has been refined down to specific data elements, software components, and hardware devices. This progressive refinement ensures traceability: every component-level decision can be traced back through logical, physical, and conceptual layers to an original business requirement.

The NIST Cybersecurity Framework provides a risk-based approach to security management but is less prescriptive about architecture than SABSA. Many organizations use SABSA to design their security architecture and NIST to manage the resulting risk posture. Each layer answers these six questions at its
SABSA uses a matrix structure based on six distinct perspectives: Business requirements and goals. Conceptual: Fundamental security concepts and principles. Logical: Security services and information architecture. Physical: Concrete security mechanisms and software. Component: Specific tools, protocols, and configurations. Operational: Day-to-day management and monitoring. The Five Ws (and How) For each layer, SABSA asks six fundamental questions: What: The assets to protect. Why: The business motivation or risk. How: The mechanisms used. Who: The people and responsibilities. Where: The locations and environments. When: The time-frames and schedules. Implementing SABSA in Modern Enterprise Many organizations use SABSA to design their security
