Node abnormity monitoring method based on access information analysis and alarm device

Abstract

The invention provides a node abnormity monitoring method and alarm device based on access information analysis, and relates to the technical field of abnormity monitoring, and the method comprises the steps: collecting the access information of a target node in real time; performing access information expectation analysis on the target node according to the real-time network state information of the network; performing exception analysis on a node access monitoring result; performing risk analysis on the target node; performing risk analysis on a plurality of other access nodes of the network to obtain a node abnormal propagation risk coefficient; calculating a node anomaly detection coefficient; and if the node anomaly detection coefficient is greater than or equal to the node anomaly detection threshold, generating an anomaly early warning signal. Through the method and the device, the technical problem in the prior art that the accurate identification of network anomalies is influenced due to neglecting of complex interrelationships and abnormal propagation effects among the nodes can be solved, the technical goal of accurately capturing the interrelationships and abnormal propagation effects among the nodes is achieved, and the technical effect of improving the accuracy of network anomaly identification is achieved.
