    The essential dynamics of information infrastructures

    This paper inquires into the complexities of contemporary IT solutions based on a case study of the EU’s eCustoms initiatives using Manuel DeLanda’s Assemblage Theory. Technological innovations have enabled information infrastructures with dramatically increased number and heterogeneity of included components, and their dynamic and unexpected interactions. Unfortunately, lack of understanding of how the increasing complexity influences development initiatives is hampering effective information infrastructure development. Assemblage Theory can be seen as holistic synthesis of previous research streams seeking to explain how information infrastructures evolve in social contexts. Accordingly, in this paper it helps us getting a holistic grasp of the complexity of contemporary IT solutions and the “essence” of their dynamics. Through Assemblage Theory we explain how the European eCustoms information infrastructure has through a dialectic between stabilizing and destabilizing processes assumed its current shape - a result of decisions taken decades ago, path dependency, complexity, and accumulated emergence

    Tracking advanced persistent threats in critical infrastructures through opinion dynamics

    Get PDF
    Advanced persistent threats pose a serious issue for modern industrial environments, due to their targeted and complex attack vectors that are difficult to detect. This is especially severe in critical infrastructures that are accelerating the integration of IT technologies. It is then essential to further develop effective monitoring and response systems that ensure the continuity of business to face the arising set of cyber-security threats. In this paper, we study the practical applicability of a novel technique based on opinion dynamics, that permits to trace the attack throughout all its stages along the network by correlating different anomalies measured over time, thereby taking the persistence of threats and the criticality of resources into consideration. The resulting information is of essential importance to monitor the overall health of the control system and cor- respondingly deploy accurate response procedures.

    Modelling interdependencies between the electricity and information infrastructures

    The aim of this paper is to provide qualitative models characterizing interdependencies related failures of two critical infrastructures: the electricity infrastructure and the associated information infrastructure. The interdependencies of these two infrastructures are increasing due to a growing connection of the power grid networks to the global information infrastructure, as a consequence of market deregulation and opening. These interdependencies increase the risk of failures. We focus on cascading, escalating and common-cause failures, which correspond to the main causes of failures due to interdependencies. We address failures in the electricity infrastructure, in combination with accidental failures in the information infrastructure, then we show briefly how malicious attacks in the information infrastructure can be addressed

    Syrian Refugees and the Digital Passage to Europe: Smartphone Infrastructures and Affordances

    Get PDF
    This research examines the role of smartphones in refugees’ journeys. It traces the risks and possibilities afforded by smartphones for facilitating information, communication, and migration flows in the digital passage to Europe. For the Syrian and Iraqi refugee respondents in this France-based qualitative study, smartphones are lifelines, as important as water and food. They afford the planning, navigation, and documentation of journeys, enabling regular contact with family, friends, smugglers, and those who help them. However, refugees are simultaneously exposed to new forms of exploitation and surveillance with smartphones as migrations are financialised by smugglers and criminalized by European policies, and the digital passage is dependent on a contingent range of sociotechnical and material assemblages. Through an infrastructural lens, we capture the dialectical dynamics of opportunity and vulnerability, and the forms of resilience and solidarity, that arise as forced migration and digital connectivity coincide

    The power of creative thinking in situations of uncertainties: the almost impossible task of protecting critical infrastructures

    Get PDF
    A good and scientific analysis starts with a closer look at the conceptualisation at hand. The definition of CIP is not easy because of its wide range. This paper examines infrastructures that are critical and need protection. Each word entails a specific connotation and is characterized by several components

    Interdisciplinary and physics challenges of Network Theory

    Full text link
    Network theory has unveiled the underlying structure of complex systems such as the Internet or the biological networks in the cell. It has identified universal properties of complex networks, and the interplay between their structure and dynamics. After almost twenty years of the field, new challenges lie ahead. These challenges concern the multilayer structure of most of the networks, the formulation of a network geometry and topology, and the development of a quantum theory of networks. Making progress on these aspects of network theory can open new venues to address interdisciplinary and physics challenges including progress on brain dynamics, new insights into quantum technologies, and quantum gravity.Comment: (7 pages, 4 figures
