Proposal Of Countermeasure Against Attacks Similar To Stuxnet

Transcript

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. DCS (Distributed Control System) 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, we 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. This is considered as a real threat to the states [1] and can lead to disasters [2]. A multitude of vulnerabilities currently affects these systems. These vulnerabilities are exploited for various reasons such as cybercrime, industrial espionage or other. The objective of our work is to analyze the workings of Stuxnet and to propose countermeasures to strengthen the security of command control systems.
