Networked control systems under certain cyber attacks are analyzed. The communication network of these control systems make them vulnerable to attacks from malicious outsiders. The authors' paper deals with two types of attacks: attacks on the network nodes and attacks on the communication between the nodes. They propose a distributed scheme to detect and isolate the attacks using observers. Furthermore, they discuss how to reduce the number of observer nodes while maintaining the coverage of the entire network.
