Security Assessment for Cyber Physical Distribution Power System Under Intrusion Attacks

Cyber Physical Security for Power Grid Protection

A Specification-based Intrusion Detection Framework for Cyber-physical Environment in Electric Power System

The emergence of high-speed networks in electric power systems creates a tight interaction of cyber infrastructure with the physical infrastructure and makes the power system susceptible to cyber penetration and attacks. To address this problem, this paper proposes an innovative approach to develop a specification-based intrusion detection framework that leverages available information provided...

Aligning Cyber-Physical System Safety and Security

Safety and security are two key properties of Cyber-Physical Systems (CPS). Safety is aimed at protecting the systems from accidental failures in order to avoid hazards, while security is focused on protecting the systems from intentional attacks. They share identical goals – protecting CPS from failing. When aligned within a CPS, safety and security work well together in providing a solid foun...

Cyber-Physical System Security and Impact Analysis

Electric power grids have been identified as critical infrastructures. They are increasingly dependent on Information and Communication Technologies (ICTs) for the operation and control of physical facilities. It can be envisioned that on top of the power infrastructure reside ICT layers that are coupled with the electric grids. As the ICT connectivity increases, so does the potential for cyber...

Characterizing Cyber-Physical Attacks on Water Distribution Systems

This work contributes a modeling framework to characterize the effect of cyber-physical attacks (CPAs) on the hydraulic behavior of water distribution systems. The framework consists of an attack model and a MATLAB toolbox named epanetCPA. The former identifies the components of the cyber infrastructure (e.g., sensors or programmable logic controllers) that are potentially vulnerable to attacks...
