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.
Reduces impact of amplification attacks that overwhelm the primary site by allowing operations to shift to an equivalent alternate site.
Alternate services reduce the impact of amplification attacks that exhaust primary telecommunications resources.
Amplification attacks that exhaust the primary path are mitigated by the existence of an independent alternate path for command traffic.
Employs controls that mitigate amplification attacks causing asymmetric resource use.
Limits amplification effects by controlling how resources are allocated under high-volume or recursive load.
