【摘要】：电力信息物理系统(cyber-physical system,CPS)中,电力系统的调度控制和生产管理高度依赖于信息系统,是网络攻击的高价值目标。鉴于攻击方选取的攻击模式和对象因目的不同而有明显差异,文章将对电力CPS的网络攻击分为无特定目的、以获取经济利益为目的、以破坏电网稳定为目的 3类,分别进行了讨论。首先结合北美电网信息系统相关大停电分析了无特定目的网络攻击和信息系统自身随机失效与异常对电网的影响;然后综述了谋求经济利益的攻击中窃电行为检测方法;最后,假定以破坏电网稳定为目的的恶意软件能借用震网病毒传播模式侵入实时控制区,结合我国与北美电力企业在SCADA系统和广域保护等系统应用上存在的差异,分析了攻击方可能选择的攻击对象、攻击模式和后果,讨论了智能电表和SCADA中的针对性入侵检测方法。
[Abstract]:The power of information system (Cyber-Physical system, physical CPS), scheduling control and production management of power system is highly dependent on information system, is a high value target of cyber attacks. In view of the fact that there were significant differences between the attack and attack mode selection of objects for different purposes, this chapter of the power CPS network attack is specific objective to obtain economic benefits for the purpose to destroy the stability of power system for the purpose of 3 categories are discussed respectively. Firstly, analysis of the specific purpose of network attack and information system from random failure and abnormal impact on power grid information system related with the North American blackout; then reviews the acts of stealing attack in the pursuit of economic interests detection method; finally, assume that damage to the power grid stability for the purpose of malicious software can use the Stuxnet virus spread patterns of invasive real-time control area, combined with China's North American Electric Power Enterprises The differences between system applications such as SCADA system and wide area protection are analyzed. The attack objects, attack modes and consequences that the attackers may choose are analyzed, and the targeted intrusion detection methods in smart meters and SCADA are discussed.
