CP-4Contingency Plan Testing
Test the contingency plan for the system {{ insert: param, cp-04_odp.01 }} using the following tests to determine the effectiveness of the plan and the readiness to execute the plan: {{ insert: param, cp-4_prm_2 }}. Review the contingency plan test results; and Initiate corrective actions, if needed.

Weaknesses this control addresses (4)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-400 | Uncontrolled Resource Consumption | 3,573 | Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption. |
CWE-770 | Allocation of Resources Without Limits or Throttling | 2,210 | Plan testing exercises resource allocation limits and throttling during simulated failures, directly addressing weaknesses that allow unbounded resource use. |
CWE-693 | Protection Mechanism Failure | 614 | The contingency plan itself is a protection mechanism; regular testing and corrective actions ensure it does not fail when activated by an incident. |
CWE-703 | Improper Check or Handling of Exceptional Conditions | 150 | Testing verifies the system's ability to detect, handle, and recover from exceptional conditions as part of the plan, reducing exploitability of improper exception handling. |
