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-754Improper Check for Unusual or Exceptional Conditions697Requires detection of unusual conditions followed by a controlled transition to the defined failure state.
CWE-755Improper Handling of Exceptional Conditions662Enforces structured response to exceptional conditions so the system cannot remain in an unsafe state.
CWE-248Uncaught Exception189Prevents abrupt termination from uncaught exceptions by requiring a defined, preserved-state failure mode.
CWE-703Improper Check or Handling of Exceptional Conditions146Mandates explicit, predictable handling of exceptional conditions rather than undefined continuation.
CWE-636Not Failing Securely ('Failing Open')27Directly requires transition to a known (secure) state on failure, preventing fail-open behavior.
CWE-390Detection of Error Condition Without Action14Ensures that detected error conditions trigger an explicit action to reach the known failure state.
