Abstract
System, device, and method of adaptive network protection for managed Internet-of-Things (IoT) services. A network traffic monitoring unit monitors data traffic, operations-and-management traffic, and control messages, that relate to cellular communication between an IoT device and a core cellular network. An IoT grouping unit groups multiple IoT devices into a particular IoT group. A baseline behavior determination unit determines a Regular Baseline Cellular Communication Behavior (RBCCB) profile that characterizes the cellular communications that are outgoing from and incoming to each member of the particular IoT group. An outlier detector subsequently detects that a particular IoT device of that particular IoT group, exhibits cellular traffic characteristics that are abnormal relative to the RBCCB profile that was characterized for that particular IoT group. An enforcement actions generator is triggered to selectively perform one or more enforcement operations, notification operations, and quarantine operations.
