Traffic flow security is the canonical defense against traffic-analysis attacks: padding/obfuscating volumes and concealing routing information defeats topology inference.

Traffic flow security is precisely the control aimed at defeating traffic analysis and metadata-derived adversary inferences that drive eavesdropping value.

Traffic flow security on downlinks defeats the metadata-only inferences (mode transitions, safing events) that downlink eavesdropping otherwise yields when payload content is encrypted.

Traffic flow security on health/state-of-health beacons reduces the value of safe-mode-indicator monitoring by obscuring beacon cadence and metadata.
