Localization method for malicious attack nodes on local area networks
Aiming at the problem of increased detection difficulty caused by the uncertainty of spatial distribution and time of local area network malicious attacks,the paper proposed an improved method for locating local area network malicious attack nodes:by analyzing the basic characteristics of malicious attacks on the local area network,the constraints were set,the abnormal variables on the local area network were determined,a multi-dimensional mapping relationship between the overall and local behaviors of the local area network were constructed,and a reasonable mechanism for detecting malicious attack nodes on the local area network were established;then,the multidimensional mapping relationship of the local area network was utilized to obtain abnormal variables in the detection variables,the basic attack variables associated with them were determined,and the local multidimensional mapping nodes were applied to match the basic attack variables,the distance parameter correction of the received signal strength indicator(RSSI)model was introduced,the anchor nodes in different positions were analyzed,and the centroid calculation was performed,to obtain the location information of malicious attack nodes and locate the malicious attack nodes in the local area network.Experimental results showed that the proposed method would help improve the detection rate and positioning accuracy,reduce the false alarm rate and positioning time,indicating that it could achieve high accuracy in detecting and locating attack nodes.
