| Abstract [eng] |
Industrial control systems are used in electric, water and wastewater, oil and natural gas, transportation, chemical, pharmaceutical and other industries. Malicious activities in industrial control systems can have a large impact in the real word such as an increased risk to human safety and health, negative impact to the environment and economy, large financial loss. Modern industrial control systems are becoming more vulnerable, because business networks and industrial networks are becoming more interconnected. Therefore, standard information technology attacks and vulnerabilities are being exploited in industrial networks. This work analyzes intrusion detection methods for industrial control networks. Based on found flaws a new system is proposed, which could detect early signs of intrusion, when the internal network is being mapped. A prototype for the proposed system is developed and analyzed. |
