Network System and Integrated Security Method for User Terminals Connected to the Internal Network and External Network Performed by the Network System

摘要

The present invention relates to a network system and an integrated security method for a user terminal connected to an internal network and an external network performed in the network system, and more particularly, by a control server, a first user terminal connected to the internal network is When the policy information is met, the access to the internal network of the first user terminal is permitted, and when the authentication information of the second user terminal connected to the external network is verified as valid by the authentication control unit, it is transmitted to the second user terminal. to establish a communication channel for the user terminal, and finally to resume the communication channel of the second user terminal when the second user terminal with the communication channel established by the control server conforms to the second internal policy information, A method of integrated security for a network system and a user terminal connected to an internal network and an external network performed in the network system, which enables the control server to manage the first user terminal connected to the first user terminal and the second user terminal connected to the external network will be.
