Abstract
A node includes: a communication circuit; a processor operatively connected to the communication circuit; and a memory operatively connected to the processor and storing a target application and an access control application, wherein the memory stores instructions that when executed by the processor, cause the node to: detect a network access event of the target application to a destination network through the access control application, identify whether a tunnel corresponding to identification information of the target application and the destination network and authorized by an external server exists, transmit a data packet of the target application through the authorized tunnel using the communication circuit, when the authorized tunnel exists, and drop the data packet of the target application, when the authorized tunnel does not exist.
