# Per-device trust from network behaviour

IEEE Xplore document **9881803**
(<https://ieeexplore.ieee.org/document/9881803>).

This paper is the citation behind the **motivation scene** in the deck —
specifically the claim that a per-host detector becomes much stronger
when its output is combined with network-level behaviour signals
(peer observations, gateway traffic patterns, cross-host relationships)
to compute a fleet-wide trust score.

## What we borrow

- **Trust as a multi-source aggregate.** A single host's classifier
  is noisy by itself; the paper makes the case that trust should
  be computed from local verdicts *plus* network behaviour, not
  either alone. Our per-host detector is positioned as one input
  to that broader signal — not a final verdict.
- **Fast-recovery framing.** Detection time gates how quickly a
  device can be reset to a known-good snapshot. The motivation scene
  borrows this framing to argue that low detection latency directly
  shrinks both blast radius (containment) and forensic dwell time
  (recovery).

## Where it differs

- Their focus is the trust-aggregation layer above per-device
  classifiers; this project focuses on the per-device classifier
  itself. The paper's argument is what makes our local model
  *worth* building well — even a lossy on-host signal is useful
  when it's combined with the rest of the fleet's view.
