Abstract

The smart grid is creating new security vulnerabilities due to the deployment of networked devices into the traditional grid. A core component of the smart grid is the advanced metering infrastructures (AMIs), which increase the attack surface due to smart devices deployed at households. Manual management of security incidents in such a large and complex system is impractical, and the need for automated response and recovery to attacks is critical. This paper addresses that challenge through two main contributions. First, we introduce and classify an extended set of AMI-specific cyber incident response actions. Second, we define a cost model and an approach to translate security properties into monetary costs. The cost model is a key element in enabling an automated response engine to make optimal decisions and mitigate cyber incidents.
AMI中自动响应和恢复响应动作的成本建模
由于将联网设备部署到传统电网中,智能电网正在产生新的安全漏洞。智能电网的核心组成部分是高级计量基础设施(ami),由于家庭中部署了智能设备,这增加了攻击面。在如此庞大而复杂的系统中手动管理安全事件是不切实际的,对攻击的自动响应和恢复的需求是至关重要的。本文通过两个主要贡献来解决这一挑战。首先,我们介绍并分类了一组扩展的ami特定网络事件响应动作。其次,我们定义了一个成本模型和一种将安全属性转换为货币成本的方法。成本模型是实现自动化响应引擎做出最佳决策和减少网络事件的关键因素。
