While electromagnetic attacks against radars can be carried out externally, primarily by military actors, research has recently shown that marine radar is also vulnerable to attacks from cyberspace. These can be carried out internally, less “loudly”, and with significantly less effort and know-how, thus posing a general threat to the shipping industry, the global maritime transport system, and world trade. Based on cyberattacks discussed in the scientific community and a simulation environment for marine radar systems, we investigate in this work to which extent existing Intrusion Detection System (IDS) solutions can secure vessels’ radar systems, how effective their detection capability is, and where their limits lie. From this, we derive a research gap for radar-specific methods and present the first two approaches in that direction. Thus, we pave the way for necessary future developments of anomaly detection specific for marine navigation radars.

While existing literature proposes effective IIDS solutions evaluated in controlled environments, their deployment in real-world industrial settings poses several challenges. This paper highlights two critical yet often overlooked aspects that significantly impact their practical deployment, i.e., the need for sufficient amounts of data to train the IIDS models and the challenges associated with finding suitable hyperparameters, especially for IIDSs training only on genuine ICS data. Through empirical experiments conducted on multiple state-of-the-art IIDSs and diverse datasets, we establish the criticality of these issues in deploying IIDSs. Our findings show the necessity of extensive malicious training data for supervised IIDSs, which can be impractical considering the complexity of recording and labeling attacks in actual industrial environments. Furthermore, while other IIDSs circumvent the previous issue by requiring only benign training data, these can suffer from the difficulty of setting appropriate hyperparameters, which likewise can diminish their performance. By shedding light on these challenges, we aim to enhance the understanding of the limitations and considerations necessary for deploying effective cybersecurity solutions in ICSs, which might be one reason why IIDSs see few deployments.

Here, blockchain technology emerges as a possible driver that satisfies demands even in settings with mutually distrustful stakeholders. We identify significant benefits achieved by blockchain technology for Industry 4.0 but also point out challenges and corresponding design options when applying blockchain technology in the industrial domain. Furthermore, we survey diverse industrial sectors to shed light on the current intersection between blockchain technology and industry, which provides the foundation for ongoing as well as upcoming research. As industrial blockchain applications are still in their infancy, we expect that new designs and concepts will develop gradually, creating both supporting tools and groundbreaking innovations. internet-of-production Springer Advances in Information Security 17 Blockchains – A Handbook on Fundamentals, Platforms and Applications 978-3-031-32145-0 10.1007/978-3-031-32146-7_17 1 JanPennekamp LennartBader EricWagner JensHiller RomanMatzutt KlausWehrle article 2024_pennekamp_supply-chain-survey ACM Computing Surveys 2024 2 1 56 2 Supply chains form the backbone of modern economies and therefore require reliable information flows. In practice, however, supply chains face severe technical challenges, especially regarding security and privacy. In this work, we consolidate studies from supply chain management, information systems, and computer science from 2010--2021 in an interdisciplinary meta-survey to make this topic holistically accessible to interdisciplinary research. In particular, we identify a significant potential for computer scientists to remedy technical challenges and improve the robustness of information flows. We subsequently present a concise information flow-focused taxonomy for supply chains before discussing future research directions to provide possible entry points. information flows; data communication; supply chain management; data security; data sharing; systematic literature review internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-pennekamp-supply-chain-survey.pdf ACM 0360-0300 10.1145/3606693 1 JanPennekamp RomanMatzutt ChristopherKlinkmüller LennartBader MartinSerror EricWagner SidraMalik MariaSpiß JessicaRahn TanGürpinar EduardVlad Sander J.

The lack of mutual trust in such networks results in challenges that are exacerbated by stringent requirements for shipping conditions or quality, and where actors may attempt to reduce costs or cover up incidents. In this paper, we develop and comprehensively study four scenarios that eventually lead to end-to-end-secured sensing in complex IoT-based supply chains with many mutually distrusting actors, while highlighting relevant pitfalls and challenges—details that are still missing in related work. Our designs ensure that sensed data is securely transmitted and stored, and can be verified by all parties. To prove practical feasibility, we evaluate the most elaborate design with regard to performance, cost, deployment, and also trust implications on the basis of prevalent (mis)use cases. Our work enables a notion of secure end-to-end sensing with minimal trust across the system stack, even for complex and opaque supply chain networks. blockchain technology; reliability; security; trust management; trusted computing; trusted execution environments internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-pennekamp-secure-sensing.pdf 2169-3536 10.1109/ACCESS.2024.3350778 1 JanPennekamp FritzAlder LennartBader GianlucaScopelliti KlausWehrle Jan TobiasMühlberg inproceedings 2024-dahlmanns-cired 2024 The increasing demands on the power grid require intelligent and flexible solutions that ensure the grid's stability. Many of these measures involve sophisticated communication between the control center and the stations that is not efficiently realizable using traditional protocols, e.g., IEC 60870-5-104. To this end, IEC 61850 introduces data models which allow flexible communication. Still, the specification leaves open how DSOs should interconnect their stations to realize resilient communication between the control center and station devices. However, DSOs require such communication to adapt modern solutions increasing the grid's capacity, e.g., adaptive protection systems. In this paper, we present our envisioned network and communication concept for future DSO's ICT infrastructures that enables the control center to resiliently and flexibly communicate with station devices. For resilience, we suggest interconnecting each station with two distinct communication paths to the control center, use MPLS-TP and MPTCP for fast failovers when a single link fails, and mTLS to protect the communication possibilities against misuse. Additionally, in accordance with IEC 61850, we envision the control center to communicate with the station devices using MMS by using the station RTU as a proxy. ven2us Proceedings of the CIRED workshop on Increasing Distribution Network Hosting Capacity 2024, June 19-20, 2024, Vienna, Austria Vienna CIRED workshop on Increasing Distribution Network Hosting Capacity 2024 June 19-20, 2024 1 MarkusDahlmanns Ina BereniceFink GerritErichsen GuosongLin ThomasHammer BurkhardBorkenhagen SebastianSchneider ChristofMaahsen KlausWehrle inproceedings 2024-basels-demo 2024 For a long time, attacks on radar systems were limited to military targets. With increasing interconnection, cyber attacks have nowadays become a serious complementary threat also affecting civil radar systems for aviation traffic control or maritime navigation. Hence, operators need to be enabled to detect and respond to cyber attacks and must be supported by defense capabilities. However, security research in this domain is only just beginning and is hampered by a lack of adequate test and development environments. In this demo, we thus present a maritime Radar Cyber Security Lab (RCSL) as a holistic framework to identify vulnerabilities of navigation radars and to support the development of defensive solutions. RCSL offers an offensive tool for attacking navigation radars and a defensive module leveraging network-based anomaly detection. In our demonstration, we will showcase the radars’ vulnerabilities in a simulative environment and demonstrate the benefit of an application-specific Intrusion Detection System.
