External Information Systems | Consistent Interests Of Consumers And Providers, v1.0

Defines conformance and assessment criteria for verifying that an organization employs organization-defined security safeguards to ensure that the interests of organization-defined external service providers are consistent with and reflect organizational interests.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.
