The unprecedented scale at which data is both produced and consumed today has generated a large demand for scalable data management solutions facilitating fast access from all over the world. As one consequence, a plethora of non-relational, distributed NoSQL database systems have risen in recent years and today's data management system landscape has thus become somewhat hard to overlook. As another consequence, complex polyglot designs and elaborate schemes for data distribution and delivery have become the norm for building applications that connect users and organizations across the globe - but choosing the right combination of systems for a given use case has become increasingly difficult as well. To help practitioners stay on top of that challenge, this book presents a comprehensive overview and classification of the current system landscape in cloud data management as well as a survey of the state-of-the-art approaches for efficient data distribution and delivery to end-user devices. The topics covered thus range from NoSQL storage systems and polyglot architectures (backend) over distributed transactions and Web caching (network) to data access and rendering performance in the client (end-user). By distinguishing popular data management systems by data model, consistency guarantees, and other dimensions of interest, this book provides an abstract framework for reasoning about the overall design space and the individual positions claimed by each of the systems therein. Building on this classification, this book further presents an application-driven decision guidance tool that breaks the process of choosing a set of viable system candidates for a given application scenario down into a straightforward decision tree.
This textbook describes the hands-on application of data science techniques to solve problems in manufacturing and the Industrial Internet of Things (IIoT). Monitoring and managing operational performance is a crucial activity for industrial and business organisations. The emergence of low-cost, accessible computing and storage, through Industrial Digital Technologies (IDT) and Industry 4.0, has generated considerable interest in innovative approaches to doing more with data. Data science, predictive analytics, machine learning, artificial intelligence and general approaches to modelling, simulating and visualising industrial systems have often been considered topics only for research labs and academic departments. This textbook debunks the mystique around applied data science and shows readers, using tutorial-style explanations and real-life case studies, how practitioners can develop their own understanding of performance to achieve tangible business improvements. All exercises can be completed with commonly available tools, many of which are free to install and use. Readers will learn how to use tools to investigate, diagnose, propose and implement analytics solutions that will provide explainable results to deliver digital transformation.

This book contributes to the scholarly debate on the forms and patterns of interaction and discourse in modern digital communication by probing some of the social functions that online communication has for its users. An array of experts and scholars in the field address a range of forms of social interaction and discourses expressed by users on social networks and in public media. Social functions are reflected through linguistic and discursive practices that are either those of 'convergence' or 'controversy' in terms of how the discourse participants handle interpersonal relations or how they construct meanings in discourses. In this sense, the book elaborates on some very central concerns in the area of digital discourse analysis that have been reported within the last decade from various methodological perspectives ranging from sociolinguistics and pragmatics to corpus linguistics. This edited collection will be of particular interest to scholars and students in the fields of digital discourse analysis, pragmatics, sociolinguistics, social media and communication, and media and cultural studies.

This book examines different aspects of network security metrics and their application to enterprise networks. One of the most pertinent issues in securing mission-critical computing networks is the lack of effective security metrics which this book discusses in detail. Since "you cannot improve what you cannot measure", a network security metric is essential to evaluating the relative effectiveness of potential network security solutions. The authors start by examining the limitations of existing solutions and standards on security metrics, such as CVSS and attack surface, which typically focus on known vulnerabilities in individual software products or systems. The first few chapters of this book describe different approaches to fusing individual metric values obtained from CVSS scores into an overall measure of network security using attack graphs. Since CVSS scores are only available for previously known vulnerabilities, such approaches do not consider the threat of unknown attacks exploiting the so-called zero day vulnerabilities. Therefore, several chapters of this book are dedicated to develop network security metrics especially designed for dealing with zero day attacks where the challenge is that little or no prior knowledge is available about the exploited vulnerabilities, and thus most existing methodologies for designing security metrics are no longer effective. Finally, the authors examine several issues on the application of network security metrics at the enterprise level. Specifically, a chapter presents a suite of security metrics organized along several dimensions for measuring and visualizing different aspects of the enterprise cyber security risk, and the last chapter presents a novel metric for measuring the operational effectiveness of the cyber security operations center (CSOC). Security researchers who work on network security or security analytics related areas seeking new research topics, as well as security practitioners including network administrators and security architects who are looking for state of the art approaches to hardening their networks, will find this book helpful as a reference. Advanced-level students studying computer science and engineering will find this book useful as a secondary text.

Currently, we see a variety of tools and techniques for specifying and implementing business processes. The problem is that there are still gaps and tensions between the different disciplines needed to improve business process execution and improvement in enterprises. Business process modeling, workflow execution and application programming are examples of disciplines that are hosted by different communities and that emerged separately from each other. In particular, concepts have not yet been fully elaborated at the system analysis level. Therefore, practitioners are faced again and again with similar questions in concrete business process projects: Which decomposition mechanism to use? How to find the correct granularity for business process activities? Which implementing technology is the optimal one in a given situation? This work offers an approach to the systematization of the field. The methodology used is explicitly not a comparative analysis of existing tools and techniques - although a review of existing tools is an essential basis for the considerations in the book. Rather, the book tries to provide a landscape of rationales and concepts in business processes with a discussion of alternatives.
Multiple antenna (MIMO) techniques are an essential component of any contemporary wireless communication system because they can significantly improve the performance over conventional single-antenna links. While MIMO techniques are relatively well understood at the link level, the interaction of multiple MIMO links and their impact on performance at the system level necessitate fundamentally new investigations. We propose a book that investigates the theoretical foundations of MIMO networks consisting of multiple simultaneous MIMO links and applies these principles in the design of next-generation wireless networks. About ten years ago, the information theoretic foundations of MIMO techniques were developed and showed the promise of using multiple antennas at both the transmitter and receiver of a wireless link. An enormous amount of research ensued to develop practical techniques for achieving these promised gains. Within the last few years, the information theory community has again made significant breakthroughs, this time in the understanding of multiuser MIMO systems. Currently in industry, new wideband wireless standards, including EV-DO Rev C, UMTS LTE, and WiMax, are under development to meet the insatiable demands for high-rate, ubiquitous wireless services. For the first time, and for all of these standards, MIMO technology will play an integral role in meeting the aggressive performance requirements for increased data rates, decreased latency, and improved coverage. Motivated by the confluence of these two eventsa "the emergence of multiuser MIMO theory and the development of commercial MIMO-based systemsa "we propose to connect the two worlds with a bookthat combines theory and practice. This book would provide a systematic survey of MIMO systems, starting with a review of MIMO link-level techniques and conventional single-antenna system-level techniques, summarizing the latest results in multiuser MIMO systems and developments in cross-layer techniques, and applying these techniques to the analysis and design of both current and future packet-based wireless networks. In addition to providing theoretical results, the book would serve as a reference for practicing communication engineers by providing useful descriptions of spatial channel models and system simulation methodologies for MIMO networks
"Moving Target Defense: Creating Asymmetric Uncertainty for Cyber Threats" was developed by a group of leading researchers. It describes the fundamental challenges facing the research community and identifies new promising solution paths. Moving Target Defense which is motivated by the asymmetric costs borne by cyber defenders takes an advantage afforded to attackers and reverses it to advantage defenders. Moving Target Defense is enabled by technical trends in recent years, including virtualization and workload migration on commodity systems, widespread and redundant network connectivity, instruction set and address space layout randomization, just-in-time compilers, among other techniques. However, many challenging research problems remain to be solved, such as the security of virtualization infrastructures, secure and resilient techniques to move systems within a virtualized environment, automatic diversification techniques, automated ways to dynamically change and manage the configurations of systems and networks, quantification of security improvement, potential degradation and more. "Moving Target Defense: Creating Asymmetric Uncertainty for Cyber Threats" is designed for advanced -level students and researchers focused on computer science, and as a secondary text book or reference. Professionals working in this field will also find this book valuable.
