“…The human being becomes a subsystem of CPS, which is an uncontrollable and unpredictable factor to CPS. The researches in [62][63][64][259][260] introduce the recent exploration from molding human being's behavior to management for this problem. What's more, CPS is tightly embedded in the physical world and will be influenced by the environment easily.…”

Though Cyber Physical Systems (CPS) become very popular in last the decade, dependability of CPS is still a critical issue and related survey is rare. We try to spell out the jigsaw of technologies and figure out the technical trends of dependable self-managing CPS. This survey first recalls the motivation and the similar concepts. By analyzing four generic architectures, we summarize the common characteristics and related assurance technologies, and propose a more generic environment-in-loop processing flow of CPS and a formal interaction flow between physical space and cyber space. Further, the similarity between correctness and dependability is formally analyzed and the new five research questions of dependable self-managing CPS are presented. Then we review the critical technologies and related correctness verification & validation (V&V) methods, the architectures for dependable self-managing CPS. Further, the detail dependability management and V&V technologies are surveyed, which covers the areas of running-time fault management methods and whole life cycle V&V technologies, maintenance and available tool sets. For holistic CPS development, Modeling techniques and MDE (model driven engineering) based V&V methods are analyzed in detail. Then we complete the jigsaw of technologies and figure out the missing part. Further, we propose the technical challenges and the further direction. To our best knowledge, this is the first comprehensive survey on dependable self-managing CPS development and evaluation.

“…In CPSs, cyber and physical processes are dependent and interact with each other through feedback control loops (e.g., embedded cyber controllers monitor and control the system physical variables, whilst physical processes affect, at the same time, the monitoring system and the computation units by wired or wireless networks [8,100,107]). The benefit of such self-adaptive capabilities is the reason why CPSs are increasingly operated in energy, transportation, medical and healthcare, and other applications [33,93,107].…”

A B S T R A C TRisk assessment must evolve for addressing the existing and future challenges, and considering the new systems and innovations that have already arrived in our lives and that are coming ahead. In this paper, I swing on the rapid changes and innovations that the World that we live in is experiencing, and analyze them with respect to the challenges that these pose to the field of risk assessment. Digitalization brings opportunities but with it comes also the complexity of cyber-phyiscal systems. Climate change and extreme natural events are increasingly threatening our infrastructures; terrorist and malevolent threats are posing severe concerns for the security of our systems and lives. These sources of hazard are extremely uncertain and, thus, difficult to describe and model quantitatively.Some research and development directions that are emerging are presented and discussed, also considering the ever increasing computational capabilities and data availability. These include the use of simulation for accident scenario identification and exploration, the extension of risk assessment into the framework of resilience and business continuity, the reliance on data for dynamic and condition monitoring-based risk assessment, the safety and security assessment of cyber-physical systems.The paper is not a research work and not exactly a review or a state of the art work, but rather it offers a lookout on risk assessment, open to consideration and discussion, as it cannot pretend to give an absolute point of view nor to be complete in the issues addressed (and the related literature referenced to).

“…Cyber–physical systems (CPSs) combine and coordinate physical processes with high automation level through interconnections via the cyber domain (Colombo, Karnouskos, Kaynak, Shi, & Yin, ; Jazdi, ; Lee, ; Wan et al., ). They are increasingly operated in aerospace, automotive, transportation, medical and healthcare, and energy (Bradley & Atkins, ; Khaitan & McCalley, ; Lee, ). Specifically to nuclear energy, the introduction of digital instrumentation and control (I&C) systems allows nuclear power plants (NPPs) to take advantage of CPSs (IAEA, ) for improved control and safety.…”

Adversarial Risk Analysis to Allocate Optimal Defense Resources for Protecting Cyber–Physical Systems from Cyber Attacks

2019

Defenders have to enforce defense strategies by taking decisions on allocation of resources to protect the integrity and survivability of cyber-physical systems (CPSs) from intentional and malicious cyber attacks. In this work, we propose an adversarial risk analysis approach to provide a novel one-sided prescriptive support strategy for the defender to optimize the defensive resource allocation, based on a subjective expected utility model, in which the decisions of the adversaries are uncertain. This increases confidence in cyber security through robustness of CPS protection actions against uncertain malicious threats compared with prescriptions provided by a classical defend-attack game-theoretical approach. We present the approach and the results of its application to a nuclear CPS, specifically the digital instrumentation and control system of the advanced lead-cooled fast reactor European demonstrator.
