Abstract
Disclosed herein are a method, a device, and a non-transitory computer readable medium for detecting user migration from an enterprise network to a non-enterprise network by using DNS probing. The method includes detecting at least one of a change in state of network connection and change in operational state of a user migration computing device. A domain name system (DNS) query is generated in response to detecting the at least one of a change in state of network connection and change in operational state of a user migration computing device. Further, the DNS query is sent to at least one of a plurality of DNS servers. If an expected DNS response is received, it is determined that the user migration computing device is in the enterprise network. If expected DNS response is not received, that the user migration computing device is outside the enterprise network.
