Zero-Retention Ephemeral Origins for Airgapped Radio Telemetry
Logging raw radio frequency metrics to persistent storage risks accidental interception and disk exhaustion over long surveillance windows. Sovereign sensor ingest pipelines must operate strictly within volatile RAM ring buffers that purge automatically on connection drop.
Ephemeral Pipeline Invariants
- Volatile Ring Buffering: Sensor frames circulate exclusively inside fixed-size kernel memory buffers (
tmpfs/ mmap). - Zero-Write Storage Gate: Daemons drop all filesystem write privileges (
fs.protected_regular = 2), blocking disk commits. - Instantaneous Panic Wipe: When host link state drops or an anomalous peer connects, memory buffers zeroize via explicit memory barriers (
memset_s).
Airgapped monitoring nodes protect signal privacy by refusing to persist demodulated RF streams across reboot boundaries.
