Requirements NIST SOURCE

Coordinate with [external organizations] to correlate and share [incident information] to achieve a cross-organization perspective on incident awareness and more effective incident responses.

Discussion (NIST Supplemental Guidance)

The coordination of incident information with external organizations—including mission or business partners, military or coalition partners, customers, and developers—can provide significant benefits. Cross-organizational coordination can serve as an important risk management capability. This capability allows organizations to leverage information from a variety of sources to effectively respond to incidents and breaches that could potentially affect the organization’s operations, assets, and individuals.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for IR-4(8) 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

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. external organizations with whom organizational incident information is to be coordinated and shared are defined;
  2. incident information to be correlated and shared with organization-defined external organizations are defined;
  3. there is coordination with <IR-04(08)_ODP[01] external organizations> to correlate and share <IR-04(08)_ODP[02] incident information> to achieve a cross-organization perspective on incident awareness and more effective incident responses.

Examine

[SELECT FROM: Incident response policy; procedures addressing incident handling; list of external organizations; records of incident handling coordination with external organizations; incident response plan; system security plan; privacy plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with incident handling responsibilities; organizational personnel with information security and privacy responsibilities; personnel from external organizations with whom incident response information is to be coordinated, shared, and correlated].

Test

[SELECT FROM: Organizational processes for coordinating incident handling information with external organizations].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-4(8). 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.
