Requirements NIST SOURCE

Provide the capability to check the integrity of information while it resides in the external system.

Discussion (NIST Supplemental Guidance)

Storage of organizational information in an external system could limit visibility into the security status of its data. The ability of the organization to verify and validate the integrity of its stored data without transferring it out of the external system provides such visibility.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. the capability is provided to check the integrity of information while it resides in the external system.

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; procedures addressing organization-controlled integrity checking; information/data and/or system services; organizational security requirements or conditions for external 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; organization personnel with integrity checking responsibilities; external providers of system services; organizational personnel with supply chain risk management responsibilities].

Test

[SELECT FROM: Organizational processes for integrity checking; mechanisms for supporting and implementing integrity checking of information in external systems].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SA-9(7). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
