Abstract

In this paper, we present some initial results about vulnerability of control systems that can be used in Internet of Things (IoT) applications. Up to our best knowledge, this paper is the first study about vulnerability of applied control systems in general, and especially in the IoT environment. The purpose of this paper is to examine fundamentals of linear control systems and consider vulnerability of its main features and concepts used in Internet of Things applications under potential malicious attacks. We examine vulnerabilities of system stability, controllability, observability, design of feedback loops, and design and placement of sensors and controllers (actuators). The detailed study is limited to the most important vulnerability issues in time-invariant, unconstrained, deterministic, linear physical systems. Several interesting and motivating examples are provided. We have outlined also some basic vulnerability studies for time-invariant nonlinear unconstrained systems, and indicate that such a study is particularly needed for distributed parameter systems that are very prone to outside physical and cyber-attacks.

CONCLUSIONS

Vulnerability of several main attributes (features) of linear control feedback systems that are integral parts of the IoT to malicious attacks was considered, and some motivating examples were presented. The study was limited to timeinvariant systems. Future research is needed to address these issues and propose the best defense strategies in cases of such attacks. It is expected that this paper will motivate corresponding vulnerability studies of time-invariant linear and nonlinear systems with algebraic constraints, and eventually the corresponding study will be extended to time varying and/or stochastic physical systems with and without constraints, as well as to distributed parameter physical systems whose dynamics is described by partial differential equations.
