Network asset correlator for cybersecurity operations
Disclosed herein are methods, systems, and processes for utilizing computing entity resolution for network asset correlation. A scanned dataset that includes newly scanned node information that identifies newly scanned nodes on a network is received from a security server. The newly scanned node information is extracted from the scanned dataset and indicates that the newly scanned nodes cannot be identified as being part of existing computing devices in the network. The newly scanned node information is processed with a network asset correlator and the processing results in a set of asset correlation results for the newly scanned nodes. An existing computing device is identified based on a highest disparate correlation probability in the set of asset correlation results and the security server is instructed to perform a security action on the identified existing computing device.
