Network security method and network security servo system

Abstract

A network security method and a network security servo system are provided. The method includes: decrypting a plurality of encrypted data points from an Internet of Things (IoT) device; aggregating the data points into a plurality of aggregated data points, wherein the plurality of aggregated data points form a plurality of data sets; retrieving a plurality of first centroid data points corresponding to the data sets, wherein the first centroid data points form a first core data set; retrieving a plurality of second centroid data points corresponding to the first core data set and a second core data set, wherein the second core data set corresponds to other IoT devices; determining whether the IoT device is in an anomaly state based on the second centroid data points; and isolating the IoT device to a specific virtual network when the IoT device is in the anomaly state. The network security method and the network security servo system can provide the network security function for the IoT device by means of the higher operational capability.
