Cloud-Assisted Dynamic Resilience for Cyber-Physical Control Systems

We are increasingly witness to the enormous security problems that cyber-physical control systems have and their susceptibility to certain types of attacks. An attractive way to coordinate the situation and ensure resilience in lineal times could be through redundancy-based restoration mechanisms. For this reason, in this article, we present a network infrastructure based on three layers, where the redundant support is primarily concentrated on a fog-based structure to protect a specific subset of cyber-physical control devices. The specification of the context and the abstract construction of the approach include a set of conceptual theories related to structural controllability, power dominance, supernode, and opinion dynamics, where the validation of the approach is subject to a practical analysis based on two threat case studies.
