Requirements NIST SOURCE

Employ [dynamic response capabilities] to respond to incidents.

Discussion (NIST Supplemental Guidance)

The dynamic response capability addresses the timely deployment of new or replacement organizational capabilities in response to incidents. This includes capabilities implemented at the mission and business process level and at the system level.

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(9) 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. dynamic response capabilities to be employed to respond to incidents are defined;
  2. <IR-04(09)_ODP dynamic response capabilities> are employed to respond to incidents.

Examine

[SELECT FROM: Incident response policy; procedures addressing incident handling; automated mechanisms supporting dynamic response capabilities; 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: Organizational processes for dynamic response capability; automated mechanisms supporting and/or implementing the dynamic response capability for the organization].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-4(9). 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.
