Verbatim from FedRAMP/rules
Providers MUST identify a set of information resources to assess for FedRAMP Certification that includes all information resources that are likely to handle federal customer data or likely to impact the confidentiality, integrity, or availability of federal customer data handled by the cloud service offering; this set of information resources is the cloud service offering.
Defined terms in this requirement
Notes
- Certain categories of cloud computing products and services are specified as entirely outside the scope of FedRAMP by the Director of the Office of Management and Budget. All such products and services are therefore not included in the cloud service offering for FedRAMP. For more, see https://fedramp.gov/scope.
- Software produced by cloud service providers that is delivered separately for installation on agency systems and not operated in a shared responsibility model (typically including agents, application clients, mobile applications, etc. that are not fully managed by the cloud service provider) is not a cloud computing product or service and is entirely outside the scope of FedRAMP under the FedRAMP Certification Act. All such software is therefore not included in the cloud service offering for FedRAMP. For more, see fedramp.gov/scope.
- All aspects of the cloud service offering are determined and maintained by the cloud service provider in accordance with related FedRAMP Certification rules and documented by the cloud service provider in their FedRAMP Certification Package.
