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-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-400 | Uncontrolled Resource Consumption | 3,800+ | 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 | 2,400+ | Plan testing exercises resource allocation limits and throttling during simulated failures, directly addressing weaknesses that allow unbounded resource use. |
CWE-693 | Protection Mechanism Failure | 700+ | 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 | 100+ | 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. |
