Patent attributes
Attacks from IoT (Internet of Things) devices (or other statins) on a Wi-Fi network are identified using heuristics. Frames are detected from an IoT device (or conventional station) over a window of time. The frame is processed to expose IoT application data from the frame over the time window. Deviations are identified in the IoT application data to detect malicious activity from the IoT device by comparing the IoT application data from at least a first time and a second time within the time. Responsive to the IoT data comparison detecting a malicious activity from the IoT device, a network security action is performed in reference to the IoT device, the network security action to prevent the malicious activity.
