    Designing Security Policies for Complex SCADA Systems Protection

    The management and protection of these SCADA systems must constantly evolve towards integrated decision making and policy driven by cyber security requirements. The current research stream in this domain aims, accordingly, to foster the smartness of the field equipment which exist through the generic concept of SCADA management and operation. Those components are governed by policies which depend on the components roles, as well as on the evolution of the crisis which also confer to the latter the latitude to react based on their own perception of the crisis evolution. Their latitude is calculated based on the component smartness and is strongly determined by, and depending on, the cyber safety of the component environment. Existing work related to crisis management tends to consider that components evolve and are organized in systems but as far as we know, no systemic solution exists which integrates all of the above requirements. This paper proposes an innovative version of ArchiMate® for the SCADA components modelling purpose to enrich their collaborations and, more particularly, the description of their behavior endorsed in the cyber-policy. Our work has been illustrated in the frame of a critical infrastructure in the field of petroleum supply and storage networks

    Introducing the STAMP method in road tunnel safety assessment

    Get PDF
    After the tremendous accidents in European road tunnels over the past decade, many risk assessment methods have been proposed worldwide, most of them based on Quantitative Risk Assessment (QRA). Although QRAs are helpful to address physical aspects and facilities of tunnels, current approaches in the road tunnel field have limitations to model organizational aspects, software behavior and the adaptation of the tunnel system over time. This paper reviews the aforementioned limitations and highlights the need to enhance the safety assessment process of these critical infrastructures with a complementary approach that links the organizational factors to the operational and technical issues, analyze software behavior and models the dynamics of the tunnel system. To achieve this objective, this paper examines the scope for introducing a safety assessment method which is based on the systems thinking paradigm and draws upon the STAMP model. The method proposed is demonstrated through a case study of a tunnel ventilation system and the results show that it has the potential to identify scenarios that encompass both the technical system and the organizational structure. However, since the method does not provide quantitative estimations of risk, it is recommended to be used as a complementary approach to the traditional risk assessments rather than as an alternative.

    The future of Cybersecurity in Italy: Strategic focus area

    Get PDF
    This volume has been created as a continuation of the previous one, with the aim of outlining a set of focus areas and actions that the Italian Nation research community considers essential. The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

    Bibliographical review on cyber attacks from a control oriented perspective

    Get PDF
    This paper presents a bibliographical review of definitions, classifications and applications concerning cyber attacks in networked control systems (NCSs) and cyber-physical systems (CPSs). This review tackles the topic from a control-oriented perspective, which is complementary to information or communication ones. After motivating the importance of developing new methods for attack detection and secure control, this review presents security objectives, attack modeling, and a characterization of considered attacks and threats presenting the detection mechanisms and remedial actions. In order to show the properties of each attack, as well as to provide some deeper insight into possible defense mechanisms, examples available in the literature are discussed. Finally, open research issues and paths are presented.Peer ReviewedPostprint (author's final draft

    A Survey of Smart Grid Systems on Electric Power Distribution Network and Its Impact on Reliability

    Get PDF
    This paper presents an excerpt of a more comprehensive survey of smart grid systems on electric power distribution networks and its impact on reliability. The survey was carried out as part of the feasibility study in Nigeria to determine its enhance-ability on the smartness of a conventional (traditional) distribution network. A smart grid is not a single technology but multiplex technologies in which the combination of different areas of engineering, communication and energy management systems are done. Consequently, a comprehensive review of various approaches and their impact on reliability of the network is presented. Furthermore, this paper introduces the smart grid technology and its features, reliability impacts and emerging issues and challenges that arise from the smart grid system applications. The benefit of this comprehensive survey is to provide a reference point for educational advancement on the recently published articles in the areas of smart grid systems on electric power distribution network as well as to stimulate further research interest
