Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0041] figure 1 The flowchart of the situational awareness method for the Internet of Things provided by this application, the method includes:

[0042] Collect the operating status data of sensors, information platforms, and detection equipment from different sources;

[0043] After receiving the collected data, clear the redundant information in the data, convert the data format into a unified format according to the type of source, divide it into corresponding fields, and merge it into a data stream;

[0044] Extract elements from the merged data stream, discover the behavior, access object, source address, and instantaneous traffic size inform...

Abstract

The invention provides a situation awareness method and system of the Internet of Things. The method comprises steps of collecting data of different information sources; obtaining data streams in a unified format through preprocessing; extracting high-frequency project group elements from the data stream; generating high frequency association rules, carrying out situation evaluation for evaluationquantification; through fusing with different evaluation systems and obfuscating the data elements, situation values of a single device and a local network are obtained, the architecture compositionof the whole network is combined; a situation value of the whole system is obtained; the situation values of different levels are imported into a neural network model for prediction; finally, the prediction result is visually displayed, the whole Internet of Things system and each single device are fully evaluated, and the prediction result can be associated with each device and each layer basedon the given situation value so that the future system can be scientifically predicted, and valuable reference suggestions can be provided for users.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method and system for situational awareness of the Internet of Things. Background technique [0002] The existing situational awareness technology can obtain the security situation assessment results of the entire system by using a simple situation understanding, but cannot quantitatively give a situation assessment report, let alone predict the security situation based on the situation assessment results. Very limited value. Especially in the Internet of Things system, there are many types of devices, each device will involve a variety of different services, and each service will encounter different attacks. [0003] The situation assessment of the Internet of Things not only fully evaluates the entire Internet of Things system and each individual device in terms of algorithms, but also can associate it with each device and each layer based on the given sit...
