Weaknesses this control addresses (7)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-754 | Improper Check for Unusual or Exceptional Conditions | 700+ | IR testing directly validates checks for unusual or exceptional conditions that could indicate security incidents. |
CWE-755 | Improper Handling of Exceptional Conditions | 600+ | Incident response testing confirms proper handling of exceptional conditions to limit exploit impact. |
CWE-703 | Improper Check or Handling of Exceptional Conditions | 100+ | Performing IR tests ensures exceptional conditions are properly checked and handled to enable effective response. |
CWE-778 | Insufficient Logging | 28 | IR testing would reveal insufficient logging that impairs incident analysis and response effectiveness. |
CWE-391 | Unchecked Error Condition | 25 | Testing IR effectiveness identifies and drives fixes for unchecked error conditions that fail to initiate incident handling. |
CWE-390 | Detection of Error Condition Without Action | 20 | IR testing verifies that detected error conditions trigger appropriate response actions rather than being ignored. |
CWE-392 | Missing Report of Error Condition | 12 | IR testing would expose missing error reporting that prevents timely incident detection and response. |
