Abstract
Methods, apparatuses, and computer program products for edge device assisted mitigation of publish-subscribe denial of service (DoS) attacks are disclosed. An edge device hosts a virtualized copy of an Internet-of-Things (IoT) device subscribed to one or more publish-subscribe topics. When the edge device receives an indication to activate the virtualized copy of the IoT device, for example, during a DoS attack on the IoT device, the edge device activates the virtualized copy of the IoT device, which receives traffic from the publish-subscribe topic. The virtualized copy of the IoT device applies security policies to incoming traffic received from the subscription topics and transmits to the IoT device sanitized traffic obtained from the received incoming subscription content traffic.
