Functional Properties of Controls
LOW ✓ MODERATE ✓ HIGHRequirements NIST SOURCE
Require the developer of the system, system component, or system service to provide a description of the functional properties of the controls to be implemented.
Discussion (NIST Supplemental Guidance)
Functional properties of security and privacy controls describe the functionality (i.e., security or privacy capability, functions, or mechanisms) visible at the interfaces of the controls and specifically exclude functionality and data structures internal to the operation of the controls.
Implementation Guidance

No engineering interpretation has been authored for SA-4(1) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.
Assessment
Assessment Objectives
- the developer of the system, system component, or system service is required to provide a description of the functional properties of the controls to be implemented.
Examine
[SELECT FROM: System and services acquisition policy; system and services acquisition procedures; procedures addressing the integration of security and privacy requirements, descriptions, and criteria into the acquisition process; solicitation documents; acquisition documentation; acquisition contracts for the system, system component, or system services; system security plan; privacy plan; other relevant documents or records].
Interview
