Cyber-Physical Industrial Control System Testbed A Cyber-Security Solution

Abstract

In this project , the hybr id testbed architecture is selected for the development of ICS testbed where the Tennessee Eastman (TE) plant is simulated inside PC and the remaining components are implemented using real indust r ial hardware. TE plant is selected as the indust r ial process for the developed cybersecur ity testbed due to the following reasons. First , the TE modTheel is a well-known chemical process plant used in cont rol systems research and it dynamics is well-understood. Second, it should be proper ly cont rolled otherwise small disturbance will dr ive the system toward an unsafe and unstable operat ion. The inherent unstable open-loop proper ty of the TE process model presents a real-wor ld scenar io in which a cyber -at tack could represent a real r isk to human safety, environmental safety, and economic viability. Third, the process is complex, coupled and nonlinear , and has many degrees of freedom by which to cont rol and per turb the dynamics of the process.
