A New Multilevel Framework for Cyber-Physical System Security

Cyber-Physical System (CPS) is a system of system which integrates physical system with cyber capability in order to improve the physical performance. It is being widely used in areas closely related to national economy and people's livelihood, therefore CPS security problems have drawn a global attention and an appropriate risk assessment for CPS is in urgent need. In this paper, a security framework for CPS is proposed. Then this paper analyzes the risk assessment on CPS these parts: assets, threat and vulnerability. At last this paper proposes a method of CPS simulation using Matlab, PLC and Emulab. Keywords-component; CPS; security; risk assessment;
