A Survey on Cyber-Resilience Approaches for Cyber-Physical Systems
Résumé
Concerns for the resilience of Cyber-Physical Systems (CPS) in critical infrastructure are growing. CPS integrate sensing, computation,
control and networking into physical objects and mission-critical services, connecting traditional infrastructure to internet technologies.
While this integration increases service efficiency, it has to face the possibility of new threats posed by the new functionalities. This
leads to cyber-threats, such as denial-of-service, modification of data, information leakage, spreading of malware, and many others.
Cyber-resilience refers to the ability of a CPS to prepare, absorb, recover, and adapt to the adverse effects associated with cyber-threats,
e.g., physical degradation of the CPS performance resulting from a cyber-attack. Cyber-resilience aims at ensuring CPS survival, by
keeping the core functionalities of the CPS in case of extreme events. The literature on cyber-resilience is rapidly increasing, leading
to a broad variety of research works addressing this new topic. In this article, we create a systematization of knowledge about existing
scientific efforts of making CPS cyber-resilient. We systematically survey recent literature addressing cyber-resilience with a focus on
techniques that may be used on CPS. We first provide preliminaries and background on CPS and threats, and subsequently survey
state-of-the-art approaches that have been proposed by recent research work applicable to CPS. In particular, we aim at differentiating
research work from traditional risk management approaches, based on the general acceptance that it is unfeasible to prevent and
mitigate all possible risks threatening a CPS. We also discuss questions and research challenges, with a focus on the practical aspects
of cyber-resilience, such as the use of metrics and evaluation methods, as well as testing and validation environments.
