Strengthen the Security of SCADA Systems Through Polling

摘要

The critical information infrastructure is a system of facilities, services, rules and ways of information processing, the suspension or disruption of the functionality of which can lead to a serious negative impact. In addition to this concept, a new area in the military and economic space is emerging - the Cyber Space Domain. The security of SCADA systems is of particular importance in strategically important for the economy industrial and infrastructure sites. The article presents a theoretical model for protection of devices operating in SCADA systems, which can directly communicate and interact with various field devices such as sensors, valves, pumps, motors, drives, etc., through a human-machine interface.
