The data of nodes in industrial Internet have characteristics of high dimensionality
redundancy and mass and traditional malicious behaviors detection model cannot make a fast and accurate judgment on the malicious behaviors of industrial Internet. A real-time detection method of malicious behaviors in industrial Internet based on feature combination optimization is proposed. The feature combination of industrial Internet malicious behaviors sample data are optimized by improved fast correlation filtering algorithm and principal component analysis algorithm based on singular value decomposition. Based on symmetric uncertainty information measurement index and approximate Markov blanket criterion
feature correlation calculation
redundant feature identification and exclusion are performed. Several candidate feature combinations are obtained from different configurations of feature dimensions; Use decision tree evaluator to select the feature combination with the highest accuracy; To acquire the optimal feature combination of lower dimension and higher valuable information
the principal component analysis of singular value decomposition is used for further reduce dimension of feature; To classify malicious behaviors samples in industrial Internet through combing extreme gradient boosting algorithm and the optimized feature combination. The proposed method is verified based on Mississippi State University's multi-class power system attack sample data; The experiment demonstrate that training time of the feature combination optimization detection model can be reduced by 57.53%
and the average detectio
n time of a single sample is 0.002 ms
which can be reduced by 23.99%. The accuracy
recall and
F
1 value of the detection model based on feature combination optimization are improved by 1.11%
1.25% and 1.01%
respectively compared with those before feature optimization. The outstanding advantage of method in this paper is that it can significantly reduce model detection time while improving model detection effect
and can better adapt to the real-time requirements of industrial Internet.
