摘　　要：入侵攻击模拟验证系统作为提高电网安全性的一种代表性工具,通过自动模拟从内外部对网络、系统和应用程序发起的广泛攻击,实现模拟攻击,评估系统安全能力。然而,针对电力网络中主要面临的长期且多阶段的高级持续攻击,现存入侵攻击模拟验证系统的设计却普遍存在一定的局限性,不能有效地进行全面模拟和防御。针对上述问题,本文提出了一种面向电力网络高级持续攻击防御的自动化入侵攻击模拟验证系统设计方案,该方案采用虚拟化与流量模拟技术实现了对电力网络的实战仿真,并在仿真环境中,通过对比防护前后攻击的效果来对高级持续攻击的防护措施进行有效性验证。本文首先基于虚拟化技术实现了针对高级持续攻击的基础网络与组件的模拟,其次采用流量模拟技术实现了系统中电网业务流量和高级持续攻击流量的双重模拟,最后搭建了面向高级持续攻击的实战场景,实现了防护措施的有效性验证模块。经试验表明,本文所提方案能够较好地进行电力网络攻防实验和防御长期多阶段的高级持续攻击。As a representative tool to improve the security of power grids, the Intrusion Attack Simulation Verification System automatically simulates a wide range of attacks on networks, systems, and applications from inside and outside, realizes simulated attacks, and evaluates system security capabilities. However, in view of the long-term and multi-stage advanced persistent attacks mainly faced in power networks, the design of the existing intrusion attack simulation and verification system has some limitations, and it cannot be effectively simulated and defended. In order to solve the above problems, this paper proposes a design scheme for the automatic intrusion attack simulation and verification system for advanced continuous attack defense of power network, which uses virtualization and traffic simulation technology to realize the ac
