Figure 6. Representative cases illustrating the complementary roles of IoT sensing data and network traffic data in AD-FIT. (A) IoT sensing data of Case 1, which show no obvious deviation from normal patterns; (B) network traffic data of Case 1, which show significant deviations in multiple features; (C) IoT sensing data of Case 2, which show pronounced fluctuations; (D) network traffic data of Case 2, which show no obvious deviation from normal patterns; (E) IoT sensing data of Case 3, in which the humidity dimension shows a slight fluctuation; and (F) network traffic data of Case 3, in which the missed_bytes feature shows a slight deviation.
