Take the following actions to verify that the interests of [external service providers] are consistent with and reflect organizational interests: [actions].

Discussion (NIST Supplemental Guidance)

As organizations increasingly use external service providers, it is possible that the interests of the service providers may diverge from organizational interests. In such situations, simply having the required technical, management, or operational controls in place may not be sufficient if the providers that implement and manage those controls are not operating in a manner consistent with the interests of the consuming organizations. Actions that organizations take to address such concerns include requiring background checks for selected service provider personnel; examining ownership records; employing only trustworthy service providers, such as providers with which organizations have had successful trust relationships; and conducting routine, periodic, unscheduled visits to service provider facilities.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. external service providers are defined;
  2. actions to be taken to verify that the interests of external service providers are consistent with and reflect organizational interests are defined;
  3. <SA-09(04)_ODP[02] actions> are taken to verify that the interests of <SA-09(04)_ODP[01] external service providers> are consistent with and reflect organizational interests.

Examine

[SELECT FROM: System and services acquisition policy; procedures addressing external system services; acquisition contracts for the system, system component, or system service; solicitation documentation; acquisition documentation; service level agreements; organizational security requirements/safeguards for external service providers; personnel security policies for external service providers; assessments performed on external service providers; system security plan; supply chain risk management plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system and service acquisition responsibilities; organizational personnel with information security responsibilities; external providers of system services; organizational personnel with supply chain risk management responsibilities].

Test

[SELECT FROM: Organizational processes for defining and employing safeguards to ensure consistent interests with external service providers; mechanisms supporting and/or implementing safeguards to ensure consistent interests with external service providers].
