    The Internet as we know it today is the result of a continuous activity for improving network communications, end user services, computational processes and also information technology infrastructures. The Internet has become a critical infrastructure for the human-being by offering complex networking services and end-user applications that all together have transformed all aspects, mainly economical, of our lives. Recently, with the advent of new paradigms and the progress in wireless technology, sensor networks and information systems and also the inexorable shift towards everything connected paradigm, first as known as the Internet of Things and lately envisioning into the Internet of Everything, a data-driven society has been created. In a data-driven society, productivity, knowledge, and experience are dependent on increasingly open, dynamic, interdependent and complex Internet services. The challenge for the Internet of the Future design is to build robust enabling technologies, implement and deploy adaptive systems, to create business opportunities considering increasing uncertainties and emergent systemic behaviors where humans and machines seamlessly cooperate

    Critical infrastructures are vital assets for public safety, economic welfare, and the national security of countries. The vulnerabilities of critical infrastructures have increased with the widespread use of information technologies. As Critical National Infrastructures are becoming more vulnerable to cyber-attacks, their protection becomes a significant issue for organizations as well as nations. The risks to continued operations, from failing to upgrade aging infrastructure or not meeting mandated regulatory regimes, are considered highly significant, given the demonstrable impact of such circumstances. Due to the rapid increase of sophisticated cyber threats targeting critical infrastructures with significant destructive effects, the cybersecurity of critical infrastructures has become an agenda item for academics, practitioners, and policy makers. A holistic view which covers technical, policy, human, and behavioural aspects is essential to handle cyber security of critical infrastructures effectively. Moreover, the ability to attribute crimes to criminals is a vital element of avoiding impunity in cyberspace. In this book, both research and practical aspects of cyber security considerations in critical infrastructures are presented. Aligned with the interdisciplinary nature of cyber security, authors from academia, government, and industry have contributed 13 chapters. The issues that are discussed and analysed include cybersecurity training, maturity assessment frameworks, malware analysis techniques, ransomware attacks, security solutions for industrial control systems, and privacy preservation methods

    In this article, we provide an introduction to simulation for cybersecurity and focus on three themes: (1) an overview of the cybersecurity domain; (2) a summary of notable simulation research efforts for cybersecurity; and (3) a proposed way forward on how simulations could broaden cybersecurity efforts. The overview of cybersecurity provides readers with a foundational perspective of cybersecurity in the light of targets, threats, and preventive measures. The simulation research section details the current role that simulation plays in cybersecurity, which mainly falls on representative environment building; test, evaluate, and explore; training and exercises; risk analysis and assessment; and humans in cybersecurity research. The proposed way forward section posits that the advancement of collecting and accessing sociotechnological data to inform models, the creation of new theoretical constructs, and the integration and improvement of behavioral models are needed to advance cybersecurity efforts

    While telemedicine and technology-enabled education are not new concepts and have significant bodies of research, in depth application to management and treatment of veteran Post-Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI) is relatively new. The conflicts in the Southwest Asia over the last two decades have significantly increased the need for healthcare and support services for these returning warriors. Creative thinking and innovative technologies are needed to meet the growing and changing demand of these patients in the face of many competing demands within the U.S. healthcare sector. This doctoral research study investigated the potential for a platform-agnostic (ad hoc) networking technology to serve as a trusted social networking and training platform for healthcare providers who are striving to provide quality healthcare that meets the needs of veterans suffering from PTSD and TBI. This research study analyzed the effectiveness of a digitally networked environment to deliver desired training and certification outcomes in a military healthcare environment. The level of acceptance of an ad hoc network technology (GridstreamRx) by healthcare professionals using it as an enabler of collaboration during the training process was evaluated. The results also assessed the readiness of healthcare professionals to use this Information Communications Technology (ICT), or analogous new applications and services, to help them perform their healthcare responsibilities. This thesis study, accomplished with the support of the U.S. Army and National Science Foundation, took place at two large military medical centers over a twelve-month period of time. Data was gathered from 568 healthcare professionals using quantitative survey instruments. Ninety-six respondents provided additional quantitative and qualitative inputs at various times during a proscribed training regimen. DeLone and McLean\u27s 2003 Information System Success Model, modified by findings of more recent research, provided the theoretical lens for analyzing the data from 32 of the training participants in determining the perceived net benefit of the GridstreamRx technology. The data gathered for the study showed, at the 95% level of confidence, that a majority of the professionals of these two medical centers would perceive a positive net benefit from using GridstreamRx in a healthcare training environment. The conclusion from this analysis was that not only are the healthcare providers in this study ready to use ICT and social networking in this professional setting, but also that GridstreamRx is an acceptable platform for performing these functions. The study participants provided input with respect to their priorities regarding information sharing techniques, functionality, and suggestions for improving the platform. The outcomes confirmed that GridstreamRx can be a successful introduction of ad hoc networking to telemedicine. This thesis concluded with recommendations for scholars and practitioners to pursue in the future; and should be followed up with further research and actions in order to build toward a Fully Integrated Virtual Healthcare Environment (FivHe)

    Finding the Missing Link between Corporate Social Responsibility and Firm Competitiveness through Social Capital: A Business Ecosystem Perspective

    Get PDF
    There are existing studies that successfully show the impact of corporate social responsibility (CSR) on firms’ financial performance. However, limited attention is paid to its impact on the business ecosystem. CSR could be seen as an investment for building a sustainable business ecosystem, which enhances the competitiveness of this system’s members. In that context, this study apprehends and captures the virtuous cycle of firm competitiveness. On analyzing data from interviews with seven firms, the study offers four propositions identifying the structure of the virtuous cycle linking CSR activities to firm competitiveness through the accumulation of social capital within business ecosystems. Based on those propositions, the study offers new insights into CSR research for academics and strategic planning guidelines for managers that integrate social and economic values for a sustainable business ecosystem and firm competitiveness

    Get PDF
    This book presents the paper form of the Special Issue (SI) on Smart Urban Water Networks. The number and topics of the papers in the SI confirm the growing interest of operators and researchers for the new paradigm of smart networks, as part of the more general smart city. The SI showed that digital information and communication technology (ICT), with the implementation of smart meters and other digital devices, can significantly improve the modelling and the management of urban water networks, contributing to a radical transformation of the traditional paradigm of water utilities. The paper collection in this SI includes different crucial topics such as the reliability, resilience, and performance of water networks, innovative demand management, and the novel challenge of real-time control and operation, along with their implications for cyber-security. The SI collected fourteen papers that provide a wide perspective of solutions, trends, and challenges in the contest of smart urban water networks. Some solutions have already been implemented in pilot sites (i.e., for water network partitioning, cyber-security, and water demand disaggregation and forecasting), while further investigations are required for other methods, e.g., the data-driven approaches for real time control. In all cases, a new deal between academia, industry, and governments must be embraced to start the new era of smart urban water systems
