[0021] see figure 2 , the embodiment of the present invention provides a method for intrusion monitoring of the Internet of Things, the method comprising:

[0022] Step S200: Acquiring data collected by sensing devices at nodes of the sensing layer of the Internet of Things;

[0023] Step S210: Based on the obtained data as training data and using the TrAdaBoost method, an Internet of Things intrusion classification model is established, wherein the Internet of Things intrusion classification includes an intrusion behavior set and a normal behavior set;

[0024] Step S220: Obtain the test data collected by the sensing device at the sensing layer node of the Internet of Things again, and use the Internet of Things intrusion classification model to perform classification judgment;

[0025] Step S230: If the test data is divided into intrusion behavior sets, interception and alarm processing are performed;

[0026] Step S240: If the test data is classified into a normal behavi...

[0029] see image 3 , the embodiment of the present invention provides a method for intrusion monitoring of the Internet of Things, the method comprising:

[0030] Step S300: Acquiring data collected by sensing devices at the sensing layer nodes of the Internet of Things;

[0031] The hierarchical structure of the Internet of Things is divided into three layers, from bottom to top: the perception layer, the network layer, and the application layer. The perception layer is the core of the Internet of Things and a key part of information collection. The perception layer is located at the bottom of the three-layer structure of the Internet of Things, and its function is "perception", that is, to obtain environmental information through the sensor network. The perception layer is the core of the Internet of Things and a key part of information collection.

[0032]The perception layer includes two-dimensional code tags and readers, RFID tags and readers, cameras, GPS, sensors, M...

Abstract

An Internet of Things intrusion monitoring method and device provided in embodiments of the present invention relate to the field of Internet of Things security. The method includes acquiring data collected by sensing devices at the sensing layer nodes of the Internet of Things; based on the acquired data as training data and using the TrAdaBoost method, establishing an Internet of Things intrusion classification model, wherein the Internet of Things intrusion classification includes An intrusion behavior set and a normal behavior set; obtain the test data collected by the perception device again at the sensing layer node of the Internet of Things, and use the Internet of Things intrusion classification model to classify and judge; if the test data is divided into an intrusion behavior set, then Interception and alarm processing are carried out to solve the problem of monitoring intrusion behaviors at the perception layer of the Internet of Things.

Description

technical field [0001] The present invention relates to the security field of the Internet of Things, in particular to a method and device for intrusion monitoring of the Internet of Things. Background technique [0002] As an important part of the communication network in the new information age, the Internet of Things communication technology can not only connect machines with machines to realize new transmission and sharing of physical world perception, but also connect machines with people to achieve a wider and more In-depth information interaction has become a new type of bridge connecting human subjective information service needs and various perception services in the objective world. The security of the perception layer of the Internet of Things is the premise and guarantee for the real practical application of the Internet of Things. The security threats faced by the sensing layer of the Internet of Things mainly include physical attacks, the danger of sensor equi...
