A brand-new edition of the popular introductory textbook that explores how computer hardware, software, and networks work Computers are everywhere. Some are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak personal data about us. Governments and companies increasingly use computers to monitor what we do. Social networks and advertisers know more about us than we should be comfortable with. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? In this updated edition of Understanding the Digital World, Brian Kernighan explains how computer hardware, software, and networks work. Topics include how computers are built and how they compute; what programming is; how the Internet and web operate; and how all of these affect security, privacy, property, and other important social, political, and economic issues. Kernighan touches on fundamental ideas from computer science and some of the inherent limitations of computers, and new sections in the book explore Python programming, big data, machine learning, and much more. Numerous color illustrations, notes on sources for further exploration, and a glossary explaining technical terms and buzzwords are included. Understanding the Digital World is a must-read for readers of all backgrounds who want to know more about computers and communications.

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.

Mobile devices, such as smart phones, have achieved computing and networking capabilities comparable to traditional personal computers. Their successful consumerization has also become a source of pain for adopting users and organizations. In particular, the widespread presence of information-stealing applications and other types of mobile malware raises substantial security and privacy concerns. Android Malware presents a systematic view on state-of-the-art mobile malware that targets the popular Android mobile platform. Covering key topics like the Android malware history, malware behavior and classification, as well as, possible defense techniques.

Media reform plays an increasingly important role in the struggle for social justice. As battles are fought over the future of investigative journalism, media ownership, spectrum management, speech rights, broadband access, network neutrality, the surveillance apparatus, and digital literacy, what effective strategies can be used in the pursuit of effective media reform? Prepared by thirty-three scholars and activists from more than twenty-five countries, Strategies for Media Reform focuses on theorizing media democratization and evaluating specific projects for media reform. This edited collection of articles offers readers the opportunity to reflect on the prospects for and challenges facing campaigns for media reform and gathers significant examples of theory, advocacy, and activism from multinational perspectives.

It’s been ten years since open data first broke onto the global stage. Over the past decade, thousands of programmes and projects around the world have worked to open data and use it to address a myriad of social and economic challenges. Meanwhile, issues related to data rights and privacy have moved to the centre of public and political discourse.

As the open data movement enters a new phase in its evolution, shifting to target real-world problems and embed open data thinking into other existing or emerging communities of practice, big questions still remain. How will open data initiatives respond to new concerns about privacy, inclusion, and artificial intelligence? And what can we learn from the last decade in order to deliver impact where it is most needed?

The State of Open Data brings together over 60 authors from around the world to address these questions and to take stock of the real progress made to date across sectors and around the world, uncovering the issues that will shape the future of open data in the years to come.

This combination book and audio instructional program is designed to diminish the accents of men and women who speak English as their second language. It will help them speak standard American English with clarity, confidence, and accuracy. Specific exercises concentrate on vowel sounds, problematic consonants such as V, W, TH, the American R, and the often confusing American T sound. It teaches them to employ correct syllable stress, emphasize the correct words in a sentence for native sounding rhythm, speak with American intonation, link words for smoother speech flow, use common word contractions, and more. Additional topics that often confuse ESL students are also discussed and explained. They include distinguishing between casual and formal speech, homophones (for instance, they're and there), recognizing words with silent letters (comb, receipt, and others), and avoiding embarrassing pronunciation mistakes, such as mixing up "beach" and "bitch." Students are familiarized with many irregular English spelling rules and exceptions, and are shown how such irregularities can contribute to pronunciation errors. A native language guide references problematic accent issues of 13 different language backgrounds. Correct lip and tongue positions for all sounds are discussed in detail. There is also a link to downloadable audio that uses male and female voices to coach correct American-style pronunciation.

Good backup and recovery strategies are key to the health of any organization. Medium- to very-large-scale systems administrators have to protect large amounts of critical data as well as design backup solutions that are scalable and optimized to meet changing conditions. Pro Data Backup and Recovery will cover some of the more common backup applications, such as Symantec NetBackup/BackupExec, EMC NetWorker, and CommVault, but the main discussion will focus on the implementation of 21st century architectures that allow the backup software to be a "commodity" item. The underlying architecture provides the framework for meeting the requirements of data protection for the organization. This book covers new developments in data protection as well as the impact of single-instance storage upon backup infrastructures. It discusses the impact of backup and data replication, the often misapplied B2D and D2D strategies, and "tapeless" backup environments. Continuous data protection and remote replication strategies are also addressed as they are integrated within backup strategies-a very important topic today. Learn backup solution design regardless of specific backup software Design realistic recovery solutions Take into account new data protection standards and the impact of data replication Whether you are using NetBackup, CommVault, or some other backup software, Pro Data Backup and Recovery will give you the information you need to keep your data safe and available.

Big data, surveillance, crisis management. Three largely different and richly researched fields, however, the interplay amongst these three domains is rarely addressed. In this enlightening title, the link between these three fields is explored in a consequential order through a variety of contributions and series of unique and international case studies. Indeed, whilst considering crisis management as an "umbrella term" that covers a number of crises and ways of managing them, the reader will also explore the collection of "big data" by governmental crisis organisations. However, this volume also addresses the unintended consequences of using such data. In particular, through the lens of surveillance, one will also investigate how the use and abuse of big data can easily lead to monitoring and controlling the behaviour of people affected by crises. Thus, the reader will ultimately join the authors in their debate of how big data in crisis management needs to be examined as a political process involving questions of power and transparency. An enlightening and highly topical volume, Big Data, Surveillance and Crisis Management will appeal to postgraduate students and postdoctoral researchers interested in fields including Sociology and Surveillance Studies, Disaster and Crisis Management, Media Studies, Governmentality, Organisation Theory and Information Society Studies.

In The United States of Anonymous, Jeff Kosseff explores how the right to anonymity has shaped American values, politics, business, security, and discourse, particularly as technology has enabled people to separate their identities from their communications. Legal and political debates surrounding online privacy often focus on the Fourth Amendment's protection against unreasonable searches and seizures, overlooking the history and future of an equally powerful privacy right: the First Amendment's protection of anonymity. The United States of Anonymous features extensive and engaging interviews with people involved in the highest profile anonymity cases, as well as with those who have benefited from, and been harmed by, anonymous communications. Through these interviews, Kosseff explores how courts have protected anonymity for decades and, likewise, how law and technology have allowed individuals to control how much, if any, identifying information is associated with their communications. From blocking laws that prevent Ku Klux Klan members from wearing masks to restraining Alabama officials from forcing the NAACP to disclose its membership lists, and to refusing companies' requests to unmask online critics, courts have recognized that anonymity is a vital part of our free speech protections. The United States of Anonymous weighs the tradeoffs between the right to hide identity and the harms of anonymity, concluding that we must maintain a strong, if not absolute, right to anonymous speech.

The Internet has been transformed in the past years from a system primarily oriented on information provision into a medium for communication and community-building. The notion of Web 2.0, social software, and social networking sites such as Facebook, Twitter and MySpace have emerged in this context. With such platforms comes the massive provision and storage of personal data that are systematically evaluated, marketed, and used for targeting users with advertising. In a world of global economic competition, economic crisis, and fear of terrorism after 9/11, both corporations and state institutions have a growing interest in accessing this personal data. Here, contributors explore this changing landscape by addressing topics such as commercial data collection by advertising, consumer sites and interactive media; self-disclosure in the social web; surveillance of file-sharers; privacy in the age of the internet; civil watch-surveillance on social networking sites; and networked interactive surveillance in transnational space. This book is a result of a research action launched by the intergovernmental network COST (European Cooperation in Science and Technology).

Failure to appreciate the full dimensions of data protection can lead to poor data protection management, costly resource allocation issues, and exposure to unnecessary risks. Data Protection: Governance, Risk Management, and Compliance explains how to gain a handle on the vital aspects of data protection. The author begins by building the foundation of data protection from a risk management perspective. He then introduces the two other pillars in the governance, risk management, and compliance (GRC) framework. After exploring data retention and data security in depth, the book focuses on data protection technologies primarily from a risk management viewpoint. It also discusses the special technology requirements for compliance, governance, and data security; the importance of eDiscovery for civil litigation; the impact of third-party services in conjunction with data protection; and data processing facets, such as the role of tiering and server and storage virtualization. The final chapter describes a model to help businesses get started in the planning process to improve their data protection. By examining the relationships among the pieces of the data protection puzzle, this book offers a solid understanding of how data protection fits into various organizations. It allows readers to assess their overall strategy, identify security gaps, determine their unique requirements, and decide what technologies and tactics can best meet those requirements.

The 2009 Australasian Conference on Information Security and Privacy was the 14th in an annual series that started in 1996. Over the years ACISP has grown froma relativelysmall conferencewith a largeproportionof paperscoming from Australia into a truly international conference with an established reputation. ACISP 2009 was held at Queensland University of Technology in Brisbane, d- ing July 1-3, 2009. This year there were 106 paper submissions and from those 30 papers were accepted for presentation, but one was subsequently withdrawn. Authors of - cepted papers came from 17 countries and 4 continents, illustrating the inter- tional ?avorof ACISP. We would like to extend our sincere thanks to all authors who submitted papers to ACISP 2009. The contributed papers were supplemented by two invited talks from e- nent researchers in information security. Basie von Solms (University of Joh- nesburg), currently President of IFIP, raised the question of how well dressed is the information security king. L. Jean Camp (Indiana University) talked about how to harden the network from the friend within. We are grateful to both of them for sharing their extensive knowledge and setting challenging questions for the ACISP 2009 delegates. We were fortunate to have an energetic team of experts who formed the Program Committee. Their names may be found overleaf, and we thank them warmly for their considerable e?orts. This team was helped by an even larger number of individuals who reviewedpapers in their particularareasof expertise.

This provocative book offers a probing account of the erosion of privacy in American society, that shows that we are often unwitting, if willing, accomplices, providing personal data in exchange for security or convenience. The author reveals that in today's "information society," the personal data that we make available to virtually any organization for virtually any purpose is apt to surface elsewhere, applied to utterly different purposes. The mass collection and processing of personal information produces such tremendous efficiencies that both the public and private sector feel justified in pushing as far as they can into our private lives. And there is no easy cure. Indeed, there are many cases where privacy invasion is both hurtful to the individual and indispensable to an organization's quest for efficiency. And as long as we willingly accept the pursuit of profit, or the reduction of crime, or cutting government costs as sufficient reason for intensified scrutiny over our lives, then privacy will remain endangered.

The Internet Age has created vast and ubiquitous databases of personal information in universities, corporations, government agencies, and doctors' offices. Every week, stories of databases being compromised appear in the news. Yet, despite the fact that lost laptops and insecure computer servers jeopardize our privacy, privacy and security are typically considered in isolation. Advocates of privacy have sought to protect individuals from snooping corporations, while advocates of security have sought to protect corporations from snooping individuals. Securing Privacy in the Internet Age aims to merge the discussion of these two goals. The book brings together many of the world's leading academics, litigators, and public policy advocates to work towards enhancing privacy and security. While the traditional adversary of privacy advocates has been the government, in what they see as the role of the Orwellian Big Brother, the principal focus of this book is the fraternity of Little Brothers-the corporations and individuals who seek to profit from gathering personal information about others.

Vast amounts of data are collected by service providers and system administ- tors, and are available in public information systems. Data mining technologies provide an ideal framework to assist in analyzing such collections for computer security and surveillance-related endeavors. For instance, system administrators can apply data mining to summarize activity patterns in access logs so that potential malicious incidents can be further investigated. Beyond computer - curity, data mining technology supports intelligence gathering and summari- tion for homeland security. For years, and most recently fueled by events such as September 11, 2001, government agencies have focused on developing and applying data mining technologies to monitor terrorist behaviors in public and private data collections. Theapplicationof data mining to person-speci?cdata raisesseriousconcerns regarding data con?dentiality and citizens' privacy rights. These concerns have led to the adoption of various legislation and policy controls. In 2005, the - ropean Union passed a data-retention directive that requires all telephone and Internetservice providersto store data ontheir consumers for up to two yearsto assist in the prevention of terrorismand organized crime. Similar data-retention regulationproposalsareunderheateddebateintheUnitedStatesCongress. Yet, the debate often focuses on ethical or policy aspects of the problem, such that resolutions have polarized consequences; e. g. , an organization can either share data for data mining purposes or it can not. Fortunately, computer scientists, and data mining researchers in particular, have recognized that technology can beconstructedtosupportlesspolarizedsolutions. Computerscientistsaredev- oping technologies that enable data mining goals without sacri?cing the privacy and security of the individuals to whom the data correspond.

This book provides emergent knowledge relating to physical, cyber, and human risk mitigation in a practical and readable approach for the corporate environment. It presents and discusses practical applications of risk management techniques along with useable practical policy change options. This practical organizational security management approach examines multiple aspects of security to protect against physical, cyber, and human risk. A practical more tactical focus includes managing vulnerabilities and applying countermeasures. The book guides readers to a greater depth of understanding and action-oriented options.

This book highlights recent advances in smart cities technologies, with a focus on new technologies such as biometrics, blockchains, data encryption, data mining, machine learning, deep learning, cloud security, and mobile security. During the past five years, digital cities have been emerging as a technology reality that will come to dominate the usual life of people, in either developed or developing countries. Particularly, with big data issues from smart cities, privacy and security have been a widely concerned matter due to its relevance and sensitivity extensively present in cybersecurity, healthcare, medical service, e-commercial, e-governance, mobile banking, e-finance, digital twins, and so on. These new topics rises up with the era of smart cities and mostly associate with public sectors, which are vital to the modern life of people. This volume summarizes the recent advances in addressing the challenges on big data privacy and security in smart cities and points out the future research direction around this new challenging topic.

Seven days a week, twenty-four hours a day, electronic databases are compiling information about you. As you surf the Internet, an unprecedented amount of your personal information is being recorded and preserved forever in the digital minds of computers. For each individual, these databases create a profile of activities, interests, and preferences used to investigate backgrounds, check credit, market products, and make a wide variety of decisions affecting our lives. The creation and use of these databases--which Daniel J. Solove calls "digital dossiers"--has thus far gone largely unchecked. In this startling account of new technologies for gathering and using personal data, Solove explains why digital dossiers pose a grave threat to our privacy.

The Digital Person sets forth a new understanding of what privacy is, one that is appropriate for the new challenges of the Information Age. Solove recommends how the law can be reformed to simultaneously protect our privacy and allow us to enjoy the benefits of our increasingly digital world.
