Our chapter book on “Security Challenges of Networked Control Systems” has been published and can be found online:
Networked control systems (NCSs) are created by the integration of advanced communication networks, control systems, and computation techniques. This integration enhances efficiency and reliability at the expense of increased complexity and reduced security . For example, the reliance of NCSs on communication networks exposes these systems to attack vectors targeting generic networks. This chapter is an overview of pervasive NCSs’ applications, recent attacks on NCSs, and attack detection techniques. A mathematical framework for an NCS under common types of attack is presented, i.e., denial of service (DoS), false data injection (FDI), and time delay switch (TDS) attacks. Thereafter, the framework is used to developed an algorithm based on adaptive channel allocation and state estimation techniques to compensate for the destabilizing effects of TDS and FDI attacks simultaneously. Finally, the proposed algorithm is used in a case study to show the effect of injected attacks on different parts of an NCS and the capabilities of the detection algorithms. Simulation results show the algorithm can accurately detect attacks and can overcome the attack effects by adapting the communication channels.
