Proposal of Countermeasure against Attacks Similar to Stuxnet

A command control system refers to a general control system of a production system of a process or of another type of dynamic system, wherein the control elements are not centralized, but are distributed throughout the system; and each component or sub- system is controlled by one or more controllers. Distributed Control System (DCS) is a computerized control system used to control the production line in the industry The entire controller system is connected via networks communication and monitoring. DCS is a very broad term used in various industries, to monitor and control distributed equipment. Nowadays, there are generally an information system upstream command control systems. To ensure the security of a system, users must secure the weakest link of this system. Thus, a flaw in the information system can lead to a multitude of command control system vulnerabilities. The objective of this article is to analyze the workings of Stuxnet, and to propose countermeasures to strengthen the security of command control systems.
