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.
Network-volume amplification against one channel can be bypassed via the pre-established alternate path.
Authorizing wireless access restricts the wireless communication channel to only intended endpoints.
Approving specific exchanges and documenting interface characteristics restricts communication channels to only intended endpoints and systems.
Limits attacker success in sustaining network amplification DoS against the primary by providing a ready alternate processing capability.
Provides continuity when primary telecom is disrupted by insufficient control of network message volume or amplification.
Limits physical connectivity to transmission channels, supporting restriction of communication paths to only intended endpoints.
Requiring providers to meet communication-channel restrictions and monitoring adherence reduces improper restriction of channels to intended endpoints.
Mandates restriction of the channel for authentication to only the intended trusted endpoints, blocking unauthorized communication paths.
