IR-4Incident Handling
Implement an incident handling capability for incidents that is consistent with the incident response plan and includes preparation, detection and analysis, containment, eradication, and recovery; Coordinate incident handling activities with contingency planning activities; Incorporate lessons learned from ongoing incident handling activities into incident response procedures, training, and testing, and implement the resulting changes accordingly; and Ensure the rigor, intensity, scope, and results of incident handling activities are comparable and predictable across the organization.

Weaknesses this control addresses (4)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-703 | Improper Check or Handling of Exceptional Conditions | 100+ | Incident handling capability directly provides structured checking and response actions for security incidents as exceptional conditions. |
CWE-778 | Insufficient Logging | 28 | Detection and analysis phases require sufficient logging to identify and investigate incidents, addressing insufficient logging. |
CWE-391 | Unchecked Error Condition | 25 | Formal incident handling procedures enforce checking and acting on error conditions that could indicate security incidents. |
CWE-390 | Detection of Error Condition Without Action | 20 | The containment, eradication, and recovery steps ensure detected incidents trigger concrete actions rather than no response. |
