We study adversarial pressures on real-time publish/subscribe visualization pipelines. We target three practicalattack classes—poison, flood, and replay—and evaluate twolightweight defenses: envelope checks and per-source quota. Usinga synthetic but calibrated harness, we show that combining the twomitigations sustains up to 2905.1 msgs/s with a minimum drop-rateof 0.03, while keeping p50/p99 detection latency near 177/352 ms.Our results … Continue reading Adversarial Robustness in Pub/Sub Visualization: Poison, Flood, and Replay
