Overview of Network Security Defense Technologies for Power Systems

Abstract

As the cybersecurity situation continues to get tougher, more and more attackers are beginning to place their attention on power system networks, and the struggle between various countries is shifting from the real world to cyberspace. Power system network security protection is crucial. Humans have become inseparable from electricity, so it is vital to ensure power security. Whether for political or war purposes, many attacks related to power systems have occurred throughout history, resulting in extremely serious consequences and extremely high property damage. And power systems require special protection due to their high speed, high energy, and high-risk characteristics. In this paper, we analyze past network attacks on electric power systems, summarize common network attacks, analyze common network security protection means in the industry, dig into the progress of network security protection research on the electric power system, explore how traditional network security protection means including firewall, antivirus software, intrusion detection, and honeypot technology are applied on the electric power system.
