Requirements NIST SOURCE

Implement a configurable capability to automatically disable the system if [security violations] are detected.

Discussion (NIST Supplemental Guidance)

Organizations consider whether the capability to automatically disable the system conflicts with continuity of operations requirements specified as part of CP-2 or IR-4(3) . Security violations include cyber-attacks that have compromised the integrity of the system or exfiltrated organizational information and serious errors in software programs that could adversely impact organizational missions or functions or jeopardize the safety of 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(5) 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. security violations that automatically disable a system are defined;
  2. a configurable capability is implemented to automatically disable the system if <IR-04(05)_ODP security violations> are detected.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-4(5). 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.
