Abstract
Network traffic logs of network traffic to and from host devices connected to a network that were collected over time are accessed. For each host device identified in the logs, a set of network traffic features indicative of whether the host device behaves like a Network Address Translation (NAT) device or an end host device is extracted from the logs for the host device. Each feature has values that vary over time based on the logs. A trained host device behavior classifier classifies the host device as either a NAT device or an end host device based on one or more of the feature values.
