Abstract

A system and a method for providing a secure network access of a terminal, the system including: a terminal; a gateway located at a boundary of a network to which the terminal belongs; and a server which manages data transmission between the terminal and the gateway. The server generates a control flow between the terminal and the server upon receiving a controller access request from the terminal; transmits, to the terminal, identification information of the control flow, and a threat detection policy stored in a database of the server; receives, from the terminal, the controller access update request including threat detection information indicating a result of executing a threat detection function installed in the terminal on the basis of the threat detection policy; and, when detection of a threat is confirmed from the threat detection information, cancels the control flow on the basis of the threat detection policy.
