Abstract

A method and a system for updating a first whitelist at a network node. The network node receives data packets from an Internet of Things (IoT) device and determines a predetermined identifier for the IoT device. The network node then determines whether the predetermined identifier is in the first whitelist. When the predetermined identifier is not in the first whitelist, the network node starts a first time period. When the predetermined identified is on the first whitelist, the network node determines whether the data packets are received within the first time period. When the data packets are received within the first time period, the network node identifies destination addresses of the data packets and updates the first whitelist based on the destination addresses and the predetermined identifier. The updated first whitelist is stored in non-transitory computer readable storage medium in the network node.
