Cyber-physical security of Wide-Area Monitoring, Protection and Control in a smart grid environment
Smart grid initiatives will produce a grid that is increasingly dependent on its cyber infrastructure in order to support the numerous power applications necessary to provide improved grid monitoring and control capabilities. However, recent findings documented in government reports and other literature, indicate the growing threat of cyber-based attacks in numbers and sophistication targeting ...
متن کاملCyber-Physical System Security of a Power Grid: State-of-the-Art
As part of the smart grid development, more and more technologies are developed and deployed on the power grid to enhance the system reliability. A primary purpose of the smart grid is to significantly increase the capability of computer-based remote control and automation. As a result, the level of connectivity has become much higher, and cyber security also becomes a potential threat to the c...
متن کاملSecurity of Information Flow in the Electric Power Grid
The confidentiality of information in a system can be breached through unrestricted information flow. The formal properties of non-deducibility and non-inference are often used to assess information flow in purely cyber environments. However, in a “cyber-physical system” (CPS), i.e., a system with significant cyber and physical components, physical actions may allow confidential information to ...
متن کاملCyber Attack Surface Analysis of Advanced Metering Infrastructure
Cyber attacks on critical infrastructure have been an issue of importance in industry over the past several years, as well as a focus of academic research. Cyber attacks of various types and magnitude have been on the rise targeted specifically at power grids. A successful attack on the power grid could result in significant impacts including grid shutdown, cascading failures, damage to the inf...
متن کاملState Estimation and Contingency Analysis of the Power Grid in a Cyber-Adversarial Environment
Contingency analysis is a critical activity in the context of the power infrastructure, because it provides a guide for resiliency and enables the grid to continue operating even in the case of failure. A critical issue with the current evolution of the power grid into a so-called smart grid is the introduction of cyber-security threats due to the pervasive deployment of communication networks ...
