Each DCS will be connected to the central server which will be the system web server. The proposed system is based on the three-tier client-server model. The application server is written in C#.Net. SQL database server 2005 is used for all the DCSs local database servers and for the system database server. Monitoring real time system alarm and all historical records are considered as part of the proposed system. The North Oil Refineries of Baiji (NORB) in northern Iraq is considered as a case study for the developed system. These refineries have twelve independent DCSs which are connected in a mesh network to form one system similar to an ordinary Supervisory Control And Data Acquisition (SCADA) system.展开更多

A terrorist attack on one oil refinery will have a catastrophic impact on oil production and the whole economy. It can also cause serious damage to the environment and even losses of human lives. The security of information systems and industrial control systems such as Supervisory Control and Data Acquisition (SCADA) systems and Distributed Control System (DCS) used in the oil industry is a major part of infrastructure protection strategy. This paper describes an attempt to use several security procedures to design a secure, robust system for the SCADA and DCS systems currently in use in the North Oil Refinery in the city of Baiji located in northern Iraq.展开更多
