作为控制电网运行的"大脑",调度自动化系统是网络攻击的高价值目标。由具有背景知识的有组织攻击方研制的针对性恶意软件,可模仿震网病毒的方式侵入调度系统发起遥控线路跳闸等选择性精确攻击。国内电力系统现有基于边界安全的纵深防护体系及在建的基于可信计算技术的防护体系均无法完全杜绝此类攻击。文中以针对性恶意软件侵入调度自动化主机不引起大停电为目标,研究基于虚构诱骗陷阱的容侵性主动安全防护作为最后一道防线。根据恶意软件可能采取的攻击策略,虚构线路作为诱骗陷阱,诱使恶意软件攻击虚构的重要元件,并在陷阱遭攻击时切换到备用调度系统以终止攻击。基于IEEE 118节点系统的仿真分...

As a “brain”to control the power grid operation, the dispatching automation system is a high-value target for cyber-attack. The targeted malware, developed by well-organized adversary with in-depth context information, could intrude into the dispatching system and initiate precise attack following the propagation pattern of Stuxnet. The likelihood of cyber-attack could not be entirely eliminated by the existing cyber security defense approaches in domestic electric power system, such as the protective systems based on network border security and trusted computing technologies. In o...
