Virtual private network (VPN) model for AIS real time monitoring

The need for a ship monitoring system based on Automatic Identification System (AIS) has been developed and provides many broad benefits for the maritime world in Indonesia. The system can become an early warning system (EWS) for ship operators, port operators, and even ship owners for tracking a movement of their ships. By internet connection based Virtual Private Network (VPN) can connect several remote base stations (RBS), VPN technology can integrate many RBS from several remote places into one AIS monitoring system. VPN-based internet connection is used to guarantee a secure network, private internet connection, and can access a network remotely. VPN technology encrypts data exchange even before data transmission reaches the public network. Connecting to the internet using a VPN connection is like accessing the internet using a special tunnel, not in the main internet network. Thus the use of a VPN-based internet connection in the AIS monitoring system can ensure the security of data transmission from RBS to the AIS monitoring server.
