A technology for controlling network access based on a tunnel and a data flow in a network environment, including a node to detect, through an access control application, a network access event in which a target application accesses a destination network; check, through the access control application, whether or not there is a tunnel generated in a unit of nodes or IPs and applied from an external server, and whether or not there is a data flow generated in a unit of TCP sessions or applications and generated by the external server; if there is the applied tunnel and data flow, transmit a data packet of the target application through the applied tunnel by using a communication circuit; and if there is no applied tunnel or data flow, drop a data packet of the target application.
