Discussion (NIST Supplemental Guidance)

To help incident response activities function as intended, organizations may use metrics and evaluation criteria to assess incident response programs as part of an effort to continually improve response performance. These efforts facilitate improvement in incident response efficacy and lessen the impact of incidents.

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-3(3) 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. qualitative data from testing are used to determine the effectiveness of incident response processes;
  2. quantitative data from testing are used to determine the effectiveness of incident response processes;
  3. qualitative data from testing are used to continuously improve incident response processes;
  4. quantitative data from testing are used to continuously improve incident response processes;
  5. qualitative data from testing are used to provide incident response measures and metrics that are accurate;
  6. quantitative data from testing are used to provide incident response measures and metrics that are accurate;
  7. qualitative data from testing are used to provide incident response measures and metrics that are consistent;
  8. quantitative data from testing are used to provide incident response measures and metrics that are consistent;
  9. qualitative data from testing are used to provide incident response measures and metrics in a reproducible format;
  10. quantitative data from testing are used to provide incident response measures and metrics in a reproducible format.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IR-3(3). 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.
