Security Requirements Traceability Matrix (srtm)

The term Security Requirements Traceability Matrix (SRTM) refers to a matrix linking security requirements to design elements, controls, implementation evidence, and test or verification activities so each requirement can be traced through the system lifecycle. It gives election, security, legal, or technical readers a specific label for the concept rather than a broader everyday meaning.

In practice, Security Requirements Traceability Matrix (SRTM) is applied to the technical or security purpose captured by its definition: a matrix linking security requirements to design elements, controls, implementation evidence. Organizations combine that function with documented procedures, authorized access, testing, monitoring, and controls appropriate to the system. The governing standard or security policy determines the exact implementation.

Understanding Security Requirements Traceability Matrix (SRTM) matters because the concept can affect security, reliability, auditability, or trusted operation. In this glossary context, it refers to a matrix linking security requirements to design elements, controls, implementation evidence. Applying the term precisely helps teams choose controls that match the actual technical function instead of assuming a broader or unrelated meaning.
