[0050] In the first embodiment of the present invention, an attack defense method is applied to Internet of Things devices, such as figure 1 As shown, the method includes the following specific steps:

[0051] Step S101, when the communication data is received, perform feature matching on the communication data and each attack data stored in the preset database.

[0052] In this embodiment, the number of preset databases is not specifically limited, and the number of preset databases is one or more.

[0053] In this embodiment, the way of matching the communication data with each attack data stored in the preset database includes but not limited to: according to the LDA (Linear Discriminant Analysis, linear discriminant analysis) algorithm, the communication data and the preset Each attack data stored in the configuration database is used for feature matching.

[0054]By performing feature matching on the communication data and each attack data stored in the preset database,...

[0062] In the second embodiment of the present invention, an attack defense method is applied to IoT devices, such as figure 2 As shown, the method includes the following specific steps:

[0063] Step S201, when the communication data is received, LDA matching analysis is performed on the communication data and each attack data stored in the preset database, so as to determine whether the characteristics of the communication data match any attack data in the preset database.

[0064] LDA is used to classify and match the communication data with each attack data stored in the preset database. The degree of coupling between classifications is low, and the degree of aggregation within the classification is high. It can effectively and quickly identify whether the communication data is attack data, and improve the accuracy of attack data. Recognition efficiency and recognition speed.

[0067] In the third embodiment of the present invention, an attack defense method is applied to IoT devices, such as image 3 As shown, the method includes the following specific steps:

[0068] Step S304, when the communication data is received, perform LDA matching analysis on the communication data and each attack data stored in the preset database, so as to judge whether the communication data matches the characteristics of any attack data in the preset database.

[0069] Step S305, when the communication data matches the characteristics of any attack data in the preset database, perform security defense processing according to the preset attack response strategy corresponding to any attack data stored in the preset database.

[0070] In this embodiment, the attack defense method further includes:

[0071] Step S301, according to the preset attack data derivation configuration strategy, derivation processing is performed on each attack data stored in the preset database t...

Abstract

The present invention proposes an attack defense method, including: when receiving communication data, performing feature matching on the communication data and each attack data stored in a preset database; In the case of a matching feature, security defense processing is performed according to a preset attack response strategy corresponding to any attack data stored in the preset database. The invention also discloses an attack defense device, an Internet of Things device, and a computer-readable storage medium. By implementing the above scheme, the ability of the Internet of Things device to respond to attacks and the self-healing ability of the Internet of Things device after being attacked are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, and in particular to an attack defense method and device, an Internet of Things device, and a computer-readable storage medium. Background technique [0002] With the continuous development of IoT technology and the continuous introduction of new IoT products, major organizations have launched IoT protocols and frameworks. The main problem solved by these IoT protocols and frameworks is the interconnection and intercommunication problem between IoT devices, that is, the connection and communication problems between IoT devices. When these IoT protocols and frameworks are to be put into application, the first problem to be faced is the security issue, and the security solutions of the existing IoT protocols and frameworks are all in their infancy, with weak ability to deal with attacks and self-healing ability. poor. Contents of the invention [0003] The present inventi...
