ICPSS Lecture Notes - Lesson 1 - Intro To Cyber-Physical Systems Security

Introduction

What are CPS’s

• Cyber-physical systems are the integration of computing and physical domains
  • usually done to improve reliability and performance

Parts of a CPS

• Generation system
  • where electrons are first generated using whatever source
• Then push into transmission system
  • transmission system is basically a wheelbarrow
• Ends in distribution system
  • step down in voltage, and leaves from there to a home

Key Equipment

• Transformer
  • steps voltage up or down as needed
• Circuit breaker
  • sits ahead of transformer and protects and other components downline
• Recloser
  • protects the circuit feeding your home, similar to a circuit breaker

Compromise

• If a component is compromised, biggest problem locally is outages
• Bigger problem is destabilization of grid, causing much larger outages
