物联网(IoT)支持的能源设备的广泛采用在提高生活质量的同时，也扩大了电网系统的攻击面。敌手可以非法控制大量这样的设备，并将它们用作危害物理网格操作的手段，这种机制称为物联网僵尸网络攻击。本文旨在提高网络物理电网对此类攻击的恢复能力。具体地说，我们使用流行病模型来理解僵尸网络的动态形成，这有助于评估网格的网络层脆弱性。攻击者的目标是利用该漏洞进行成功的物理危害，而系统运营商的目标是通过降低网络风险来确保电网的正常运行。我们开发了一个有效防御设计的优化框架，通过考虑战略攻击行为来增强网络物理网格的弹性。案例研究证实了所设计的方法。
The wide adoption of Internet of Things (IoT)enabled energy devices improves the quality of life, but simultaneously, it enlarges the attack surface of the power grid system. The adversary can gain illegitimate control of a large number of these devices and use them as a mean to compromise the physical grid operation, a mechanism known as the IoT botnet attack. This paper aims to improve the resiliency of cyberphysical power grids to such attacks. Specifically, we use an epidemic model to understand the dynamic botnet formation which facilitates the assessment of cyber layer vulnerability of the grid. The attacker aims to exploit this vulnerability to enable a successful physical compromise, while the system operator’s goal is to ensure a normal operation of the grid by mitigating cyber risks. We develop an optimization framework for effective defense design that enhances cyber-physical grid resiliency by considering strategic attack behaviors. Case studies are used to corroborate the devised approach
