NIST guidance classifies security controls as Response:

Production, development, and test refer to different environments or stages in a system's lifecycle, not the intrinsic classification of security controls themselves.

NIST Special Publication 800-53 categorizes security controls as Technical (implemented by information systems), Operational (implemented by people), and Management (focused on the organization's risk management and oversight functions).

While NIST also classifies controls as system-specific, common, and hybrid, this categorizes them by their applicability, whereas Technical, Operational, and Management classifies them by their nature or type.

People, process, and technology are general components of an organization's security posture, but not the specific classification used by NIST for its security controls.
