Network inventory management and anomaly detection system

Abstract

A method of generating a consolidated asset inventory database. The method creates a consolidated asset inventory based on asset information obtained from various sources, in which asset objects are associated with various asset attributes. The consolidation includes, for a given network infrastructure asset, identifying asset data from multiple sources relating to the same asset based on common identifier values and combining the identified asset data into a consolidated data representation of the asset associated with the common identifier value(s) and including attributes from the multiple sources. After identifying an asset attribute for which a value in the consolidated asset data representation is missing or invalid, a trained prediction model is applied to other attributes of the asset to generate a predicted value for the identified attribute which is stored in the consolidated asset data representation in the database. Methods for identifying network connectivity and detecting network anomalies are also disclosed.
