Work-in-Progress: Reliability Evaluation of Power SCADA System with Three-Layer IDS

Yenan Chen, Linsen Li, Zhaoqian Zhu, Yue Wu

Abstract: The SCADA (Supervisory Control And Data Acquisition) has become ubiquitous in industrial control systems. However, it may be exposed to cyber attack threats when it accesses the Internet. We propose a three-layer IDS (Intrusion Detection System) model, which integrates three main functions: access control, flow detection and password authentication. We use the reliability test system IEEE RTS-79 to evaluate the reliability. The experimental results provide insights into the establishment of the power SCADA system reliability enhancement strategies.
