Digital Twins for Cyber-Physical Systems Security (Dagstuhl Seminar 22171)

Authors: Alvaro Cárdenas Mora, Simin Nadjm-Tehrani, Edgar Weippl, and Matthias Eckhart

Published in: Dagstuhl Reports, Volume 12, Issue 4 (2022)

Abstract
Cyber-physical systems (CPSs) may constitute an attractive attack target due to the increased networking of components that yields an expanded attack surface. If their physical control capabilities are compromised, safety implications may arise. Thus, it is vital that the CPSs being engineered are thoroughly tested and that adequate response measures can be realized upon detecting intruders during operation. However, security testing is hard to conduct due to expensive hardware, limited maintenance periods, and safety risks. Furthermore, the increased stealthiness of threat actors requires new intrusion detection and response methods. Interestingly, digital twins have become an important concept in industrial informatics to solve similar problems, yet with a non-security-related focus: Digital twins that virtually replicate the real systems provide cost-efficient modeling, testing, monitoring, and even predictive capabilities. However, until recently, the digital-twin concept has mainly focused on production optimizations or design improvements without considering its potential for CPS security. The Dagstuhl Seminar 22171 "Digital Twins for Cyber-Physical Systems Security" therefore aimed to serve as an interdisciplinary, open knowledge-sharing platform to investigate the benefits and challenges of applying the digital-twin concept to improve the security of CPSs.

Managing Industrial Control Systems Security Risks for Cyber Insurance (Dagstuhl Seminar 21451)

Authors: Simon Dejung, Mingyan Liu, Arndt Lüder, and Edgar Weippl

Published in: Dagstuhl Reports, Volume 11, Issue 10 (2022)

Abstract
Industrial control systems (ICSs), such as production systems or critical infrastructures, are an attractive target for cybercriminals, since attacks against these systems may cause severe physical damages/material damages (PD/MD), resulting in business interruption (BI) and loss of profit (LOP). Besides financial loss, cyber-attacks against ICSs can also harm human health or the environment or even be used as a kind of weapon. Thus, it is of utmost importance to manage cyber risks throughout the ICS’s lifecycle (i.e., engineering, operation, decommissioning), especially in light of the ever-increasing threat level that is accompanied by the progressive digitization of industrial processes. However, asset owners may not be able to address security risks sufficiently, nor adequately quantify them in terms of their potential impact (physical and non-physical) and likelihood. A self-deceptive solution might be using insurance to transfer these risks and offload them from their balance sheet since the underlying problem remains unsolved. The reason for this is that the exposure for asset owners remains and mitigation measures may still not be implemented adequately while the insurance industry is onboarding unassessed risks and covering it often without premium and without managing the potential exposure of accumulated events. The Dagstuhl Seminar 21451 "Managing Industrial Control Systems Security Risks for Cyber Insurance" aimed to provide an interdisciplinary forum to analyze and discuss open questions and current topics of research in this area in order to gain in-depth insights into the security risks of ICSs and the quantification thereof.

Blockchains, Smart Contracts and Future Applications (Dagstuhl Seminar 18152)

Authors: Foteini Baldimtsi, Stefan Katzenbeisser, Volkmar Lotz, and Edgar Weippl

Published in: Dagstuhl Reports, Volume 8, Issue 4 (2018)

Abstract
This report documents the Dagstuhl seminar 18152 "Blockchains, Smart Contracts & Future Applications". While Bitcoin currently works well in practice, there are many open questions regarding the long-term perspective of blockchain technologies, for both public and private/permissioned blockchains. It is yet unclear how processes can be designed to work in predictive ways and how to embed security in the lifecycle of smart contract development and deployment. Furthermore, the distributed nature of the system needs to be considered when thinking about which groups or individuals can influence future developments. Similar to 'real-world' societies, blockchains are based on mutual recognition of conventions. Diverse academic disciplines as well as industry can and need to collaborate to advance research in blockchain and to fully understand how the technology might impact our future lives.
