Research on Enterprise Network Topology Anomaly Detection Techniques

Abstract

At present,the enterprise network management system presents the network connections between nodes in the form of network topology,so that the network topology can be visualized.However,the enterprise network itself is complex.With the increase of enterprise business,the number of network nodes increases,resulting in the complexity between node connections,therefore, this paper regards the changes of node connections in the network as exceptions and a network topology anomaly detection technique based on link redundancy preprocessing is proposed for enterprise intranet.The technique detects the abnormal situation in the network topology to locate the equipment failure and promptly discovers the violations of network access control behaviors and illegal intrusions to enhance network security.
