The present invention relates to an apparatus and a method for remotely dividing an access network. More specifically, the present invention secures security applied to a physical network separation constitution by perfectly dividing communication traffic of an external network and an internal network in a logical network separation constitution by relaying remote access for the external network of an internal network terminal by controlling the session interworking process of data of the external network and an access control message through a separated communication channel; maintains compatibility between the different communication protocols or the different operating systems and improves the security of the network separation by relaying the remote access between the access session and the data session by relaying the remote access by reconstructing the external network data received from the external network terminal and the access control message of the internal network terminal after a parsing process; and improves the efficiency of management and the convenience of usage in the network separation constitution by effectively controlling the security and the usage according to a security level in each user and by controlling the relaying the access session and the data session by analyzing the access control message and the external network data according to the monitoring rule of usage management control and rule based security control. |
