Requirements NIST SOURCE

Implement an incident handling capability for incidents involving insider threats.

Discussion (NIST Supplemental Guidance)

Explicit focus on handling incidents involving insider threats provides additional emphasis on this type of threat and the need for specific incident handling capabilities to provide appropriate and timely responses.

Engineering Interpretation

No engineering interpretation has been authored for IR-4(6) 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. an incident handling capability is implemented for incidents involving insider threats.

Examine

[SELECT FROM: Incident response policy; procedures addressing incident handling; mechanisms supporting incident handling; system design documentation; system configuration settings and associated documentation; incident response plan; system security plan; audit records; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with incident handling responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Incident handling capability for the organization].

Overlays

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-4(6). 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.
