“…To accommodate the changes in the operating context scenario, the AAPM uses a three-dimensional risk assessment tool. An example of this tool was the risk assessment cube introduced by Lanzrath et al (2020) in their research to evaluate the risk of electromagnetic attacks on smart grid substations (Lanzrath et al , 2020, p. 175).…”

PurposeDisturbances in terms of major crises such as pandemics, fluctuations in demand and oil price, energy consumption and supply chain can significantly impair the maintenance programs effectiveness and efficiency. Hence, there is an urgent need for an agile asset performance management (AAPM) framework.Design/methodology/approachThis paper's main objective is to design a comprehensive framework for an AAPM system that sustains the desired asset performance by reacting efficiently, quickly and intelligently to the changes in the operating context parameters and asset health conditions. Such a framework is adaptive to changes in scenarios and aims to systematise the decision support process, considering different objectives.FindingsThe development of the proposed framework has led to identifying an innovative way of seamless integration between crucial reliability and asset management tools. Also, the methodology implementation is expected to promote the practical use of its reliability tools and enable asset stakeholders to break silo working for clear communication around asset performance.Originality/valueThe implementation of the AAPM framework follows a new approach developed during this research and coined by the authors as the “8S approach.”

“…Under this scope, a threat that is growing in concern by experts and entities worldwide is the use of Intentional Electromagnetic Interference (IEMI). In this threat, perpetrators employ electromagnetic interference to disrupt, deceive or damage electronics of critical assets LANZRATH, SUHRKE and HIRSCH (2019). Considering the power and communication system onboard ships, electromagnetic disturbance can affect a vessel by two coupling means.…”

“…Therefore, the risk management process is particular for each sector to be evaluated since the threat scenarios may vary accordingly to the different HPEM sources and the target environment. In the context of offshore CIs, such as energy and airport infrastructures, the risk of HPEM has been investigated in recent years LANZRATH, SUHRKE and HIRSCH (2019);KRETH et al (2012). However, there is no evidence in the scientific literature of studies covering this threat to maritime vessels.…”

Known as Intentional Electromagnetic Interference (IEMI), perpetrators employ electromagnetic sources to intentionally disrupt, deceive or damage electronic devices by broadcasting or injecting disturbance signals. Modern ships are vulnerable to IEMI as they increasingly rely on electronic devices for their power, control, communication, and navigation systems. The prolonged disruption of the Global Positioning System (GPS) would bring huge financial losses to the maritime sector, for example. Given the wide range of attack possibilities employing electromagnetic interference, this paper discusses and contrasts different IEMI threats for the maritime application, divided here into jamming, spoofing, and use of high-power electromagnetic (HPEM) sources. For the case of HPEM, this paper proposes a simplified model to estimate the field strength at targeted electronics part of ships for HPEM weapons located in vicinities. Finally, this paper also presents guidelines oriented for stakeholders in the maritime sector on how to increase the IEMI security level of their assets.

“…Standardization offers a certain protection level against standardized attacks but attackers may develop their own strategies according to their technological expertise and imagination [2]. This a major concern regarding advanced digital technologies within smart grids [3], wire communications [4] (introducing repetitive crosstalk disturbances), wireless communications [5] [6], autonomous vehicles [7]. From the point of view of risk analysis or attack optimization, evaluation of worse or more favorable configurations are also the subject of questions.…”

In this paper, we apply a novel wavefront shaping technique within a cable network. By manipulating an array of crosstalk sources at different locations of the network, we demonstrate experimentally a strong enhancement of the intensity at a specific wire end where an impedance change occurs. The optimal wavefront for maximal focusing is determined noninvasively using the generalized Wigner-Smith operator. Our approach relies on two successive measurements of the scattering matrix measured at the injection ports, before and after the change. The optimal wavefront then closely corresponds to the first eigenstate of the generalized Wigner-Smith operator. Thus, a maximum intensity may be reached at a remote distance without cooperation of the target, opening up new perspectives in the context of electromagnetic aggressions or attacks (cybersecurity).
