Weaknesses this control addresses (5)AI
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-693 | Protection Mechanism Failure | 476 | Supplies a backup mechanism that continues to function when the primary information protection or integrity control fails. |
CWE-610 | Externally Controlled Reference to a Resource in Another Sphere | 234 | Limits impact of an externally controlled reference to a primary information resource by switching to an identified alternative. |
CWE-15 | External Control of System or Configuration Setting | 59 | Provides fallback sources for configuration or settings when the primary is externally corrupted or controlled. |
CWE-653 | Improper Isolation or Compartmentalization | 52 | Implements compartmentalization across independent information sources so that compromise of one does not disable essential operations. |
CWE-642 | External Control of Critical State Data | 18 | Directly counters external corruption or unavailability of critical state data by mandating and using alternative sources for essential functions. |
