Hacking Risk Analysis of Web Trojan in Electric Power System

The threat from web Trojan in electric power systems (EPS) is complex, which perhaps infects computers, damage SCADA system, or even cause electricity fail. The paper presents the potential Trojan attack risks of EPS by analyzing the security architecture of power systems, such as firewall, intrusion detection system and intrusion prevention system. The paper analyzed some possible attack methods from web Trojan and Botnet. In order to find or track the possible Trojan attacks, the detection and defense methods in virtual power system surroundings, such as web-based SCADA system, VMware station, honeynet, anti-Trojan software and operation system security, are presented.
