An embodiment of the invention provides a system for detecting Internet of Things sensing layer intrusion. The system comprises a sensor, communication equipment, a router and a data analysis server, wherein the communication equipment is respectively coupled with the sensor, the router and the data analysis server, and the router is coupled with the data analysis server. The system has the advantages that a first threshold and a second threshold are determined according to the fusion variation value of current environment data and by using preset-duration environment data, an appropriate intrusion detecting model is dynamically selected to perform intrusion detection on a current traffic data packet, and the advantages of different intrusion models are fully utilized to allow the intrusion detection result to be accurate.
Description
technical field [0001] The invention relates to the field of the Internet of Things, in particular to an intrusion detection system for the perception layer of the Internet of Things. Background technique [0002] Sensors, as the perception devices of the perception layer of the Internet of Things, have high requirements for data security. Once illegal or bad data flows into the network through the perception layer devices, it will not only destroy the security of the perception data of the entire network, but also endanger the The data security of the connected information transmission layer and even the information processing layer brings unpredictable damage to the entire Internet of Things. Therefore, in order to ensure the security of the entire network data, intrusion detection is of great significance. [0003] Since the data acquired by the sensing devices of the sensing layer will change with the continuous changes of the monitoring environment, the existing intrus...
