Abstract: A network traffic analysis method for tracking, analyzing, and mitigating security threats in a network includes receiving information based on monitoring traffic at a plurality of layers at one or more monitors deployed in the network utilizing deep packet inspection; receiving information based on monitoring the traffic at an endpoint of the network; analyzing the monitored traffic from the endpoint and the one or more monitors to determine network infrastructure and cyber security posture of the network infrastructure; and providing visualizations based on the network infrastructure and the cyber security posture, continuously to track threats, watch lateral movement in the network of the traffic, and determine security event history in the network.
