This open access book presents the main scientific results from the H2020 GUARD project. The GUARD project aims at filling the current technological gap between software management paradigms and cybersecurity models, the latter still lacking orchestration and agility to effectively address the dynamicity of the former. This book provides a comprehensive review of the main concepts, architectures, algorithms, and non-technical aspects developed during three years of investigation; the description of the Smart Mobility use case developed at the end of the project gives a practical example of how the GUARD platform and related technologies can be deployed in practical scenarios. We expect the book to be interesting for the broad group of researchers, engineers, and professionals daily experiencing the inadequacy of outdated cybersecurity models for modern computing environments and cyber-physical systems.

Social networks have created a plethora of problems regarding privacy and the protection of personal data. The use of social networks has become a key concern of legal scholars, policy-makers and the operators as well as users of those social networks. This pathbreaking book highlights the importance of privacy in the context of today's new electronic communication technologies as it presents conflicting claims to protect national and international security, the freedom of the Internet and economic considerations. Using the New Haven School of Jurisprudence's intellectual framework, the author presents the applicable law on privacy and social media in international and comparative perspective, focusing on the United States, the European Union and its General Data Protection Regulation of 2018 as well as Germany, the United Kingdom and Latin America. The book appraises the law in place, discusses alternatives and presents recommendations in pursuit of a public order of human dignity.

This surprising study of online political mobilization shows that money and organizational sophistication influence politics online as much as off, and casts doubt on the democratizing power of digital activism. The internet has been hailed as a leveling force that is reshaping activism. From the Arab Spring and Occupy Wall Street to Black Lives Matter and #MeToo, digital activism seemed cheap, fast, and open to all. Now this celebratory narrative finds itself competing with an increasingly sinister story as platforms like Facebook and Twitter-once the darlings of digital democracy-are on the defensive for their role in promoting fake news. While hashtag activism captures headlines, conservative digital activism is proving more effective on the ground. In this sharp-eyed and counterintuitive study, Jen Schradie shows how the web has become another weapon in the arsenal of the powerful. She zeroes in on workers' rights advocacy in North Carolina and finds a case study with broad implications. North Carolina's hard-right turn in the early 2010s should have alerted political analysts to the web's antidemocratic potential: amid booming online organizing, one of the country's most closely contested states elected the most conservative government in North Carolina's history. The Revolution That Wasn't identifies the reasons behind this previously undiagnosed digital-activism gap. Large hierarchical political organizations with professional staff can amplify their digital impact, while horizontally organized volunteer groups tend to be less effective at translating online goodwill into meaningful action. Not only does technology fail to level the playing field, it tilts it further, so that only the most sophisticated and well-funded players can compete.

"Amateur hour has arrived, and the audience is running the show
"
In a hard-hitting and provocative polemic, Silicon Valley insider and pundit Andrew Keen exposes the grave consequences of today's new participatory Web 2.0 and reveals how it threatens our values, economy, and ultimately the very innovation and creativity that forms the fabric of American achievement.
Our most valued cultural institutions, Keen warns--our professional newspapers, magazines, music, and movies--are being overtaken by an avalanche of amateur, user-generated free content. Advertising revenue is being siphoned off by free classified ads on sites like Craigslist; television networks are under attack from free user-generated programming on YouTube and the like; file-sharing and digital piracy have devastated the multibillion-dollar music business and threaten to undermine our movie industry. Worse, Keen claims, our "cut-and-paste" online culture--in which intellectual property is freely swapped, downloaded, remashed, and aggregated--threatens over 200 years of copyright protection and intellectual property rights, robbing artists, authors, journalists, musicians, editors, and producers of the fruits of their creative labors.
In today's self-broadcasting culture, where amateurism is celebrated and anyone with an opinion, however ill-informed, can publish a blog, post a video on YouTube, or change an entry on Wikipedia, the distinction between trained expert and uninformed amateur becomes dangerously blurred. When anonymous bloggers and videographers, unconstrained by professional standards or editorial filters, can alter the public debate and manipulate public opinion, truth becomes a commodity to be bought, sold, packaged, and reinvented.
The very anonymity that the Web 2.0 offers calls into question the reliability of the information we receive and creates an environment in which sexual predators and identity thieves can roam free. While no Luddite--Keen pioneered several Internet startups himself--he urges us to consider the consequences of blindly supporting a culture that endorses plagiarism and piracy and that fundamentally weakens traditional media and creative institutions.
Offering concrete solutions on how we can reign in the free-wheeling, narcissistic atmosphere that pervades the Web, THE CULT OF THE AMATEUR is a wake-up call to each and every one of us.

Friendship is regarded as crucial to living a good life. But how does friendship make our lives better? Do all friendships make our lives better? What sorts of interactions are necessary for maintaining valuable friendships? This book answers these questions via a philosophical exploration of friendship and the ways that it contributes value to our lives. Diane Jeske uses this philosophical analysis to assess the impact of our ever-growing use of social media: Do interactions via social media interfere with our ability to maintain genuine friendships? Do such interactions undermine the contribution of friendship to the value of our lives? In addressing these topics, Jeske examines the contemporary notion of a 'frenemy,' the ways in which we deliberately craft our social media personas, the role of the physical body in friendship, and the ways in which social media's exacerbation of our fear of being left out and of comparison-based envy can impact our relationships. Written in a clear and engaging style, Friendship and Social Media brings philosophical rigor and clarity to the task of determining how we can responsibly use social media in our own lives. It is essential reading for anyone interested in the ethics of interpersonal relationships and the social impact of technology.

Many of the most dynamic public companies, from Alibaba to Facebook to Visa, and the most valuable start-ups, such as Airbnb and Uber, are matchmakers that connect one group of customers with another group of customers. Economists call matchmakers multisided platforms because they provide physical or virtual platforms for multiple groups to get together. Dating sites connect people with potential matches, for example, and ride-sharing apps do the same for drivers and riders. Although matchmakers have been around for millennia, they're becoming more and more popular--and profitable--due to dramatic advances in technology, and a lot of companies that have managed to crack the code of this business model have become today's power brokers. Don't let the flashy successes fool you, though. Starting a matchmaker is one of the toughest business challenges, and almost everyone who tries to build one, fails. In Matchmakers, David Evans and Richard Schmalensee, two economists who were among the first to analyze multisided platforms and discover their principles, and who've consulted for some of the most successful platform businesses in the world, explain how matchmakers work best in practice, why they do what they do, and how entrepreneurs can improve their chances for success. Whether you're an entrepreneur, an investor, a consumer, or an executive, your future will involve more and more multisided platforms, and Matchmakers--rich with stories from platform winners and losers--is the one book you'll need in order to navigate this appealing but confusing world.

DDoS Attacks: Evolution, Detection, Prevention, Reaction, and Tolerance discusses the evolution of distributed denial-of-service (DDoS) attacks, how to detect a DDoS attack when one is mounted, how to prevent such attacks from taking place, and how to react when a DDoS attack is in progress, with the goal of tolerating the attack. It introduces types and characteristics of DDoS attacks, reasons why such attacks are often successful, what aspects of the network infrastructure are usual targets, and methods used to launch attacks. The book elaborates upon the emerging botnet technology, current trends in the evolution and use of botnet technology, its role in facilitating the launching of DDoS attacks, and challenges in countering the role of botnets in the proliferation of DDoS attacks. It introduces statistical and machine learning methods applied in the detection and prevention of DDoS attacks in order to provide a clear understanding of the state of the art. It presents DDoS reaction and tolerance mechanisms with a view to studying their effectiveness in protecting network resources without compromising the quality of services. To practically understand how attackers plan and mount DDoS attacks, the authors discuss the development of a testbed that can be used to perform experiments such as attack launching, monitoring of network traffic, and detection of attacks, as well as for testing strategies for prevention, reaction, and mitigation. Finally, the authors address current issues and challenges that need to be overcome to provide even better defense against DDoS attacks.

The information infrastructure - comprising computers, embedded devices, networks and software systems - is vital to operations in every sector: chemicals, commercial facilities, communications, critical manufacturing, dams, defense industrial base, emergency services, energy, financial services, food and agriculture, government facilities, healthcare and public health, information technology, nuclear reactors, materials and waste, transportation systems, and water and wastewater systems. Global business and industry, governments, indeed society itself, cannot function if major components of the critical information infrastructure are degraded, disabled or destroyed.Critical Infrastructure Protection XIV describes original research results and innovative applications in the interdisciplinary field of critical infrastructure protection. Also, it highlights the importance of weaving science, technology and policy in crafting sophisticated, yet practical, solutions that will help secure information, computer and network assets in the various critical infrastructure sectors. Areas of coverage include: Aviation Infrastructure Security; Vehicle Infrastructure Security; Telecommunications Systems Security; Industrial Control Systems Security; Cyber-Physical Systems Security; and Infrastructure Modeling and Simulation. This book is the fourteenth volume in the annual series produced by the International Federation for Information Processing (IFIP) Working Group 11.10 on Critical Infrastructure Protection, an international community of scientists, engineers, practitioners and policy makers dedicated to advancing research, development and implementation efforts focused on infrastructure protection. The book contains a selection of sixteen edited papers from the Fourteenth Annual IFIP WG 11.10 International Conference on Critical Infrastructure Protection, held at SRI International, Arlington, Virginia, USA in the spring of 2020. Critical Infrastructure Protection XIV is an important resource for researchers, faculty members and graduate students, as well as for policy makers, practitioners and other individuals with interests in homeland security.

This volume focuses on predicting users' attendance at a future event at specific time and location based on their common interests. Event attendance prediction has attracted considerable attention because of its wide range of potential applications. By predicting event attendance, events that better fit users' interests can be recommended, and personalized location-based or topic-based services related to the events can be provided to users. Moreover, it can help event organizers estimating the event scale, identifying conflicts, and help manage resources. This book first surveys existing techniques on event attendance prediction and other related topics in event-based social networks. It then introduces a context-aware data mining approach to predict the event attendance by learning how users are likely to attend future events. Specifically, three sets of context-aware attributes are identified by analyzing users' past activities, including semantic, temporal, and spatial attributes. This book illustrates how these attributes can be applied for event attendance prediction by incorporating them into supervised learning models, and demonstrates their effectiveness through a real-world dataset collected from event-based social networks.

An optimistic and nuanced portrait of a generation that has much to teach us about how to live and collaborate in our digital world. Born since the mid-1990s, members of Generation Z comprise the first generation never to know the world without the internet, and the most diverse generation yet. As Gen Z starts to emerge into adulthood and enter the workforce, what do we really know about them? And what can we learn from them? Gen Z, Explained is the authoritative portrait of this significant generation. It draws on extensive interviews that display this generation's candor, surveys that explore their views and attitudes, and a vast database of their astonishingly inventive lexicon to build a comprehensive picture of their values, daily lives, and outlook. Gen Z emerges here as an extraordinarily thoughtful, promising, and perceptive generation that is sounding a warning to their elders about the world around them-a warning of a complexity and depth the "OK Boomer" phenomenon can only suggest. Much of the existing literature about Gen Z has been highly judgmental. In contrast, this book provides a deep and nuanced understanding of a generation facing a future of enormous challenges, from climate change to civil unrest. What's more, they are facing this future head-on, relying on themselves and their peers to work collaboratively to solve these problems. As Gen Z, Explained shows, this group of young people is as compassionate and imaginative as any that has come before, and understanding the way they tackle problems may enable us to envision new kinds of solutions. This portrait of Gen Z is ultimately an optimistic one, suggesting they have something to teach all of us about how to live and thrive in this digital world.

This book presents refereed proceedings of the Third International Conference on Advances in Cyber Security, ACeS 2021, held in Penang, Malaysia, in August 2021.

The papers are organized in the following topical sections: Internet of Things, Industry 4.0 and Blockchain, and Cryptology; Digital Forensics and Surveillance, Botnet and Malware, DDoS, and Intrusion Detection/Prevention; Ambient Cloud and Edge Computing, SDN, Wireless and Cellular Communication; Governance, Social Media, Mobile and Web, Data Privacy, Data Policy and Fake News.

This book stems from the CyberBRICS project, which is the first major attempt to produce a comparative analysis of Internet regulations in the BRICS countries - namely, Brazil, Russia, India, China, and South Africa. The project has three main objectives: 1) to map existing regulations; 2) to identify best practices; and 3) to develop policy recommendations in the various areas that compose cybersecurity governance, with a particular focus on the strategies adopted by the BRICS countries to date. Each study covers five essential dimensions of cybersecurity: data protection, consumer protection, cybercrime, the preservation of public order, and cyberdefense. The BRICS countries were selected not only for their size and growing economic and geopolitical relevance but also because, over the next decade, projected Internet growth is expected to occur predominantly in these countries. Consequently, the technology, policy and governance arrangements defined by the BRICS countries are likely to impact not only the 3.2 billion people living in them, but also the individuals and businesses that choose to utilize increasingly popular applications and services developed in BRICS countries according to BRICS standards. Researchers, regulators, start-up innovators and other Internet stakeholders will find this book a valuable guide to the inner workings of key cyber policies in this rapidly growing region.

This book addresses challenges that new technologies and the big data revolution pose to existing regulatory and legal frameworks. The volume discusses issues such as blockchain and its implications for property transactions and taxes, three (or four) dimensional title registration, land use and urban planning in the age of big data, and the future of property rights in light of these changes. The book brings together an interdisciplinary collection of chapters that revolve around the potential influence of disruptive technologies on existing legal norms and the future development of real estate markets. The book is divided into five parts. Part I presents a survey of the current available research on blockchain and real estate. Part II provides a background on property law for the volume, grounding it in fundamental theory. Part III discusses the changing landscapes of property rights while Part IV debates the potential effects of blockchain on land registration. Finally the book concludes with Part V, which is devoted to new technological applications relevant to real estate. Providing an interdisciplinary perspective on emerging technologies that have the potential to disrupt the real estate industry and the regulation of it, this book will appeal to a broad audience, consisting of scholars, policy-makers, practitioners, and students, interested in real estate, law, economics, blockchain, and technology policy.

'A major analysis of our world's political crisis' - Joel Wainwright The collapse of neoliberal hegemony in the western world following the financial crash of 2007-8 and subsequent rise of right-wing authoritarian personalities has been described as a crisis of 'the political' in western societies. But the crisis must be seen as global, rather than focusing on the west alone. Pakistan is experiencing rapid financialisation and rapacious capture of natural resources, overseen by the country's military establishment and state bureaucracy. Under their watch, trading and manufacturing interests, property developers and a plethora of mafias have monopolised the provision of basic needs like housing, water and food, whilst also feeding conspicuous consumption by a captive middle-class. Aasim Sajjad-Akhtar explores neoliberal Pakistan, looking at digital technology in enhancing mass surveillance, commodification and atomisation, as well as resistance to the state and capital. Presenting a new interpretation of our global political-economic moment, he argues for an emancipatory political horizon embodied by the 'classless' subject.

This book discusses issues relating to the application of AI and computational modelling in criminal proceedings from a European perspective. Part one provides a definition of the topics. Rather than focusing on policing or prevention of crime - largely tackled by recent literature - it explores ways in which AI can affect the investigation and adjudication of crime. There are two main areas of application: the first is evidence gathering, which is addressed in Part two. This section examines how traditional evidentiary law is affected by both new ways of investigation - based on automated processes (often using machine learning) - and new kinds of evidence, automatically generated by AI instruments. Drawing on the comprehensive case law of the European Court of Human Rights, it also presents reflections on the reliability and, ultimately, the admissibility of such evidence. Part three investigates the second application area: judicial decision-making, providing an unbiased review of the meaning, benefits, and possible long-term effects of 'predictive justice' in the criminal field. It highlights the prediction of both violent behaviour, or recidivism, and future court decisions, based on precedents. Touching on the foundations of common law and civil law traditions, the book offers insights into the usefulness of 'prediction' in criminal proceedings.

Pensar el estudio de la comunicacion como una "guerra" implica reconocer que este no es un campo de estudio delimitado por una sola disciplina o una estricta definicion del concepto "comunicacion". Exige, tambien, identificar diversas tradiciones de investigacion, asi como explorar los principales dilemas que han guiado varias disciplinas en distintas epocas historicas y latitudes del mundo. Esta coleccion de tres volumenes propone, entonces, analizar la comunicacion y los medios desde diversas trincheras. Estos diversos panoramas, enfoques, tradiciones, epocas, escuelas, autores y sus preocupaciones dialogan entre si. No hay consensos definitivos; pero tampoco perdedores o ganadores en el debate. La "guerra" consiste, entonces, en identificar lo que esta en juego, en reconocer la diversidad de opiniones e intereses y en considerar el vasto arsenal disponible para resolver los grandes dilemas de la comunicacion. Volumen II. Tradiciones de pensamiento y escuelas Este segundo volumen de La comunicacion y sus guerras teoricas. Introduccion a las teorias de la comunicacion y los medios analiza y contrasta distintas escuelas de pensamiento comunmente ancladas en fronteras nacionales: la influencia norteamericana, el pensamiento frances, la Escuela de Frankfurt, los estudios culturales ingleses, la propuesta de la Escuela Invisible, los planteamientos de la escuela canadiense o el enfoque critico desde America Latina. Estas diversas tradiciones han evolucionado de manera paralela, pero desde trincheras y paradigmas encontrados. Sin embargo, los analisis en este tomo de expertas y expertos en cada tradicion dejan ver que es posible rastrear origenes e intereses comunes. Y aunque las diferencias siguen siendo evidentes, en la mayoria de los casos residen en aspectos menos visibles como: el regimen politico bajo el cual estas escuelas se desarrollan, el interes, el financiamiento e incluso, el impulso que las y los propios academicos dan a algunos temas frente a otros.

Approximately 80 percent of the world's population now owns a cell phone, which can hold evidence or contain logs about communications concerning a crime. Cameras, PDAs, and GPS devices can also contain information related to corporate policy infractions and crimes. Aimed to prepare investigators in the public and private sectors, Digital Forensics for Handheld Devices examines both the theoretical and practical aspects of investigating handheld digital devices. This book touches on all areas of mobile device forensics, including topics from the legal, technical, academic, and social aspects of the discipline. It provides guidance on how to seize data, examine it, and prepare it as evidence for court. This includes the use of chain of custody forms for seized evidence and Faraday Bags for digital devices to prevent further connectivity and tampering of evidence. Emphasizing the policies required in the work environment, the author provides readers with a clear understanding of the differences between a corporate investigation and a criminal investigation. The book also: Offers best practices for establishing an incident response policy and seizing data from company or privately owned digital devices Provides guidance in establishing dedicated examinations free of viruses, spyware, and connections to other devices that could taint evidence Supplies guidance on determining protocols for complicated crime scenes with external media and devices that may have connected with the handheld device Considering important privacy issues and the Fourth Amendment, this book facilitates an understanding of how to use digital forensic tools to investigate the complete range of available digital devices, including flash drives, cell phones, PDAs, digital cameras, and netbooks. It includes examples of commercially available digital forensic tools and ends with a discussion of the education and certifications required for various careers in mobile device forensics.

Governing Privacy in Knowledge Commons explores how privacy impacts knowledge production, community formation, and collaborative governance in diverse contexts, ranging from academia and IoT, to social media and mental health. Using nine new case studies and a meta-analysis of previous knowledge commons literature, the book integrates the Governing Knowledge Commons framework with Helen Nissenbaum's Contextual Integrity framework. The multidisciplinary case studies show that personal information is often a key component of the resources created by knowledge commons. Moreover, even when it is not the focus of the commons, personal information governance may require community participation and boundaries. Taken together, the chapters illustrate the importance of exit and voice in constructing and sustaining knowledge commons through appropriate personal information flows. They also shed light on the shortcomings of current notice-and-consent style regulation of social media platforms. This title is also available as Open Access on Cambridge Core.

Sponsored by the Communication, Information Technologies, and Media Sociology section of the American Sociological Association (CITAMS), this volume focuses on media and social movements. Contributing authors draw on cases as diverse as the Harry Potter Alliance to youth oriented, non-profit educational organizations, in order to assess systematically how media environments, systems, and usage affect collective action in the 21st century. The volume demonstrates that the study of media and social movements has developed into a vibrant sub-field stretched across Communication Studies, Political Science, and Sociology, and illustrates the need for serious interdisciplinary research. Chapters in the volume reinforce the need to examine many kinds of media (such as fiction) for social movements, particularly in terms of recruitment and framing. They show the critical importance of connecting classic and contemporary social movement research when trying to understand topics such as recruitment, identity, and discourse, even when these are playing out in the digital world. Chapters explore the difficulties that organizations face in organizing whether or not they are primarily offline or online; the ways that digital media usage affects various organizational functions and effectiveness; and the importance of examining the role of youth in social movements across all of these topics.

Exploring the social implications of digital transformation, as well as demonstrating how we might use digital transformation to further sociological knowledge, this incisive Handbook provides an extensive overview of cutting-edge research on the digital turn of modern society. Bringing together contributions from more than 60 experts spanning a wide range of disciplines, Jan Skopek explores how digital technologies inextricably permeate the ways we go about our everyday lives, from how we seek information and carry out economic transactions to how we construct our identities and pursue and maintain social relationships. Chapters investigate timely issues related to social theory and social research in the digital age, including the study of online behaviour, digital social inequalities, and the micro- and macro-level consequences of digital technological change. Covering state-of-the-art quantitative and qualitative research methodologies in digital sociology, this Research Handbook serves as a comprehensive resource for teaching and research in a continually developing field. Cross-disciplinary in scope, this dynamic Research Handbook will be essential reading for a diverse audience of academics, researchers, students, and practitioners, particularly in the fields of sociology, demography, computer and information sciences, economics, business, and psychology.
