The proposed security agent, Internet of Things Active Management Unit IoTAMU, provides confidentiality of IoT networks via the following capabilities 1 authentication, 2 firewall, 3 encryption, and 4 spoofing. To test the spoofers effect, an Identical Device Model Classifier IDMC is developed, which measures the similarities of the observed network signatures of each pair of devices, and recognize identical model devices. The IDMC performs well in baseline network settings without the spoofer, achieving 100 precision, recall, and specificity at high threshold SS0.9. When the spoofer is enabled, none of the identical pairs are identified at high threshold, and up to 66 identical pairs are identified at lower thresholdsSS0.8, 0.7. Overall, the spoofer is able to sufficiently modify the observed network signatures of each device the observed differences between each pair increase overall p-value 0.01132 at 120 spoofed samples, making it more difficult to identify similar devices. Finally, the experiments in this work show the spoofer has a negligible effect on network congestion.
