Results From this, we gave each device an overall rating for each category. If a device passed a test it was rated "good" (represented by green "A" boxes in the tables); if it failed it was "poor" (red "C" boxes). If it did not pass the test but the attack was unsuccessful, it was rated as average (yellow "B" boxes). The grey boxes Based on the major threats we identified, Figures 1-4 show how each IoT device performed in the four categories - confidentiality, integrity and authentication, access control, and the ability to withstand reflective attacks.
