Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-405

Reduces impact of amplification attacks that overwhelm the primary site by allowing operations to shift to an equivalent alternate site.

addresses: CWE-405

Alternate services reduce the impact of amplification attacks that exhaust primary telecommunications resources.

addresses: CWE-405

Amplification attacks that exhaust the primary path are mitigated by the existence of an independent alternate path for command traffic.

addresses: CWE-405

Employs controls that mitigate amplification attacks causing asymmetric resource use.

addresses: CWE-405

Limits amplification effects by controlling how resources are allocated under high-volume or recursive load.
