Abstract
The system and method for correlating network identities and addresses described herein may include a log correlation engine distributed on a network that identifies relationships between certain network identities and Internet Protocol (IP) and Ethernet addresses in the network. In particular, the log correlation engine may analyze various event logs that describe activity in a network to learn relationships between network identities and network addresses and generate alerts in response to discovering changes in the learned relationships. For example, the log correlation engine may identify authentication events described in the logs to map network identities to IP addresses, and may further analyze the logs to map the IP addresses to Ethernet addresses. Thus, the log correlation engine may discover new and changed relationships between the network identities, the IP addresses, and the Ethernet addresses.
