中文摘要
针对敌对势力有组织性网络攻击呈现为高级持续性威胁(Advanced Persistent Threat,APT)和协同攻击、电网信息物理系统(Cyber-Physical Systems,CPS)中协同网络攻击引发跨空间级联故障机理不明确、无法建立有效防御体系的问题,从电网CPS整体视角,研究协同网络攻击下电网CPS跨空间级联故障演化机理和早期防御方法,以保障电网的安全稳定运行:研究协同网络攻击与电网级联故障之间的耦合触发逻辑,提出考虑耦合触发逻辑的跨空间级联故障演化模型;从攻击者视角建立考虑多重动态因素的协同网络攻击约束条件集合,研究与最优协同网络攻击决策对偶的动态规划问题及其求解方法;研究协同网络攻击下的跨空间级联故障早期预警方法,并从防御者视角建立考虑多重动态因素的最优防御方案动态规划问题并提出求解方法,为实现电网CPS跨空间级联故障的早期预警和有效主动防御提供理论与方法支撑。
英文摘要
The organized cyberattacks lunched by hostile forces are usually advanced persistent threats (APT) and coordinated attacks. The mechanism of cascading failures across spaces caused by coordinated cyberattacks in Grid Cyber-Physical Systems (GCPS) is unclear, so that it is difficult to construct an effective defense system. To solve this problem, the evolution mechanism, early warning and defense methods of cascading failures across spaces caused by coordinated cyberattacks are investigated from the overall perspective of GCPS, so as to ensure the safe and stable operation of GCPS. Firstly, the coupling triggering logic between coordinated cyberattacks and cascading failures in GCPS is studied, and the evolution model of cascading failures across spaces considering the coupling triggering logic is proposed. Then, a set of coordinated cyberattacks constraint conditions considering multiple dynamic factors is constructed from the attacker's perspective, and the solutions of dynamic programming problems for optimal coordinated cyberattacks decision is studied. Finally, in order to support for both security situation awareness and effective dynamic defense of GCPS, a novel early warning model of cascading failures across spaces considering coordinated cyberattacks is proposed, and a dynamic programming problem considering multiple dynamic factors is established from the defender's perspective and its solution method is presented. This work could be the theory basis of early warning and active defense systems for cascading failures in GCPS caused by coordinated cyberattacks.
