Intentional and unintentional cyber threats are an ever-present risk for such critical infrastructures and for businesses that rely on 100 percent uptime of their operational facilities. The need for remote monitoring, control, maintenance, and data access have resulted in many Supervisory Control and Data Acquisition (SCADA) systems and Distributed Control Systems (DCS) to be accessible either directly from the Internet or through corporate networks. This paper proposed a Distributed Control System Network Architecture for Securing SCADA system. It is consists of a layered defense-in-depth approach that will enable administrator to watch their networks at every level. The primary concerns for the control system network includes securing remote access, validating and authenticating every device and user on the control system network, and assuring the integrity of the data.
