Embodiment Construction

[0036] 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.

[0037] figure 1 The flow chart of the situational awareness method including correlation analysis provided for this application, the method includes:

[0038] Collect the operating status data of sensors, information platforms, and detection equipment from different sources;

[0039] 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;

[0040] Extract elements from the merged data stream, discover the behavior, access object, source address, and instantaneous traffic siz...

Abstract

The invention provides a situation awareness method and a system containing correlation analysis. The method comprises the 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, situation evaluation is carried outfor evaluation quantification; performing fusion with different evaluation systems; and obfuscating the data elements, obtaining situation values of a single device and a local network; obtaining a situation value of the whole system according to the architecture composition of the whole network; importing the situation values of different levels into a neural network model for prediction; and finally, visually displaying a prediction result, fully evaluating the whole system and each single device, establishing association between each device and each layer, and performing rule detection andrisk value calculation on different rules, thereby scientifically predicting a future system and providing valuable reference suggestions for users.

Description

technical field [0001] The present application relates to the technical field of network security, and in particular to a situation awareness method and system including correlation analysis. 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. [0003] Situation assessment including correlation analysis not only fully evaluates the entire system and each individual device in terms of algorithms, but also associates it with each device and each layer based on the given situation value, and performs rule detection for different rules , to calculate the risk value, so that the future system can be predicted scientifically, and valuable reference suggestions can be provided fo...
