Suddenly your Web server becomes unavailable. When you investigate, you realize that a flood of packets is surging into your network. You have just become one of the hundreds of thousands of victims of a denial-of-service attack, a pervasive and growing threat to the Internet. What do you do? Internet Denial of Service sheds light on a complex and fascinating form of computer attack that impacts the confidentiality, integrity, and availability of millions of computers worldwide. It tells the network administrator, corporate CTO, incident responder, and student how DDoS attacks are prepared and executed, how to think about DDoS, and how to arrange computer and network defenses. It also provides a suite of actions that can be taken before, during, and after an attack. Inside, you'll find comprehensive information on the following topics How denial-of-service attacks are waged How to improve your network's resilience to denial-of-service attacks What to do when you are involved in a denial-of-service attack The laws that apply to these attacks and their implications How often denial-of-service attacks occur, how strong they are, and the kinds of damage they can cause Real examples of denial-of-service attacks as experienced by the attacker, victim, and unwitting accomplices The authors' extensive experience in handling denial-of-service attacks and researching defense approaches is laid out clearly in practical, detailed terms.
Disseminating Security Updates at Internet Scale describes a new system, "Revere", that addresses these problems. "Revere" builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. "Revere" also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure "Revere" overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of "Revere" gathered using a large-scale oriented approach. These measurements suggest that "Revere" can deliver security updates at the required scale, speed and resiliency for a reasonable cost. Disseminating Security Updates at Internet Scale will be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by "Revere". The "Revere" solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.
Internet heterogeneity is driving a new challenge in application development: adaptive software. Together with the increased Internet capacity and new access technologies, network congestion and the use of older technologies, wireless access, and peer-to-peer networking are increasing the heterogeneity of the Internet. Applications should provide gracefully degraded levels of service when network conditions are poor, and enhanced services when network conditions exceed expectations. Existing adaptive technologies, which are primarily end-to-end or proxy-based and often focus on a single deficient link, can perform poorly in heterogeneous networks. Instead, heterogeneous networks frequently require multiple, coordinated, and distributed remedial actions. Conductor: Distributed Adaptation for Heterogeneous Networks describes a new approach to graceful degradation in the face of network heterogeneity - distributed adaptation - in which adaptive code is deployed at multiple points within a network. The feasibility of this approach is demonstrated by conductor, a middleware framework that enables distributed adaptation of connection-oriented, application-level protocols. By adapting protocols, conductor provides application-transparent adaptation, supporting both existing applications and applications designed with adaptation in mind. Conductor: Distributed Adaptation for Heterogeneous Networks introduces new techniques that enable distributed adaptation, making it automatic, reliable, and secure. In particular, we introduce the notion of semantic segmentation, which maintains exactly-once delivery of the semantic elements of a data stream while allowing the stream to be arbitrarily adapted in transit. We also introduce a secure architecture for automatic adaptor selection, protecting user data from unauthorized adaptation. These techniques are described both in the context of conductor and in the broader context of distributed systems. Finally, this book presents empirical evidence from several case studies indicating that distributed adaptation can allow applications to degrade gracefully in heterogeneous networks, providing a higher quality of service to users than other adaptive techniques. Further, experimental results indicate that the proposed techniques can be employed without excessive cost. Thus, distributed adaptation is both practical and beneficial. Conductor: Distributed Adaptation for Heterogeneous Networks is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate-level students in computer science.
Over a century ago a series of shocking mutilation murders took place in a squalid, overcrowded district of Victorian London. Five women fell victim to a man driven by rage and violent fantasy. The newspapers of the day gave him a chilling nickname, a name that evokes images of gas-lit foggy streets and a top-hatted sinister figure carrying a Gladstone bag. From the outset, the murderer attained almost mythical status merely by virtue of his name and his uncanny ability to avoid detection. The legend of Jack the Ripper was born. Peter Hodgson’s detailed and entertaining overview of Ripper lore in fact, film and fiction analyses the fiend’s awesome legacy. He explores the institutions and the individuals: the Jewish community and their rituals with meat, the scandal-prone royal family, the Victorian police and their simplistic methods of investigation, the streetwalkers and their trade. This book compares the fiction with the reality of those ghastly events, and clearly shows how the real killer has been transformed into a creature of the mind–the ‘other’ Jack the Ripper. Examination of the victims’ mutilations reveals the true nature of ‘Jack’s’ grotesque fantasies. This aspect–coupled with his elementary anatomical knowledge–is used in conjunction with the FBI’s appraisal of the case to construct a unique psychological profile. From the long list of candidates the author reveals his prime suspect for the role of the world’s most infamous serial killer. Book reviews online: PublishedBestsellers website.

The aim of this book is to bring together the information available on established clostridial diseases of the gastrointestinal tract, including the more recent observations with respect to the mechanisms of action and to critically review the data available which implicate clostridia in the gastrointestinal diseases of unknown etiology such as infantile necrotizing enterocolitis and large bowl cancer. Information on the wide range of gut diseases in animals, both natural and laboratory induced, in which clostridia have been shown to be involved or are being implicated, has been included, as in many instances these observations sever to help delineate the etiologies of human disease.

William Avery Bishop is recognized as the British EmpireÕs highest-scoring WWI ace, credited with 72 combat victories, third-ranking behind von Richthofen and Ren Fonck. He scored many of his successes on his own, prevailing only by dint of personal courage, daring and superior marksmanship. This remarkable manÕs story has been detailed in many books and articles, but renowned author Peter Kilduff is adamant that so far the full truth has not been told. Famed for his evenhanded, thorough, exhaustive and forensic research, Kilduff sets out to bring new light to missions and kills so far steeped in controversy. As so many of BishopÕs victories were achieved during solo combat, all will be examined and scrutinized, drawing on German, British and Canadian archival sources, BishopÕs private correspondence, and accounts by friends and foes. Such an approach provides as complete an account as possible which also serves as a valuable reference work containing many previously unpublished images.
Portraying themselves as challenging blind religious dogma with evidence-led skepticism, the neo-atheist movement claims that the New Testament contains unreliable tales about a mythical figure who, far from being the resurrected Lord of life, may not even have lived. This comprehensive critique documents the falsehood of these neo-atheist claims, correcting their historical and philosophical mistakes to show how we can get at the truth about the historical Jesus.
Deutschland ist durch seine regionale Struktur - mit vielen Zentren intensiver wirtschaftlicher Aktivität - besonders interessant für Analysen zu räumlichen Mechanismen von Städten und zu Wechselwirkungen zwischen Regionen. Mit steigender Bevölkerungszahl in den Städten dient das Pendeln zwischen Wohn- und Arbeitsort als räumlicher Ausgleichsmechanismus und führt zu Interaktionen zwischen regionalen Arbeitsmärkten. Der Autor untersucht, wie lokale Arbeitsmärkte interagieren, wie stark besiedelte Märkte bei der Suche nach einem neuen Arbeitsplatz helfen und wie Beschäftigte auf Änderungen ihrer Pendlerdistanzen reagieren. Die verschiedenen Blickwinkel und die Verwendung von Mikro- und georeferenzierten Daten bieten neue empirische Erkenntnisse über die Interaktionen zwischen regionalen Arbeitsmärkten und das Mobilitätsverhalten in Deutschland.

When first published in 2006, Rats Alley was a ground-breaking piece of research, the first-ever study of trench names of the Western Front. Now, in this fully updated and revised second edition, the gazetteer has been extended to well over 20,000 trench names, complete with map references – in itself an essential tool for any First World War researcher. However, combined with the finely considered history and analysis of trench naming during the First World War, this is an edition that no military history enthusiast should be without. Discover when, how and why British trenches were first named and follow the names' fascinating development throughout the First World War, alongside details of French and German trench-naming practices. Looked at from both contemporary and modern points of view, the names reveal the full horror of trench warfare and throw an extraordinary sidelight on the cultural life of the period, and the landscape and battles of the Western Front. Names such as Lovers Lane, Idiot Corner, Cyanide Trench, Crazy Redoubt, Doleful Post, Furies Trench, Peril Avenue, Lunatic Sap and Gangrene Alley can be placed in context. With useful information on where original trench maps are held, and how to obtain copies, Rats Alley is a vital volume for both military and family historians.

Bridging the clinical electrophysiological investigation with the neurological consultation Acutely ill patients present with symptoms that don’t immediately yield a diagnosis. Electrophysiological testing can support diagnosis but only if the appropriate tests are ordered. They must be properly interpreted in conjunction with the actual symptoms. Clinical Electrophysiology presents a wide range of symptoms with specific electrophysiological results. The handbook shows how the complete picture leads to better diagnostic, prognostic or therapeutic conclusions. The book is organized by the presenting neurological problem in a clinical setting. For each case the authors provide a possible electrophysiological result. This is interpreted and tied to the patient’s symptoms to yield a clinical solution. The handbook avoids theoretical discussion to provide a direct practical guide that: Begins with the patient’s symptoms Uses a range of electrophysiological modalities Shows different test results for similar symptoms Relates clinical observation to electrophysiological testing A final casebook section presents readers with rarer clinical challenges for self-testing. Providing practical, to-the-point guidance on electrophysiological investigations, Clinical Electrophysiology will guide all neurologists attending acutely ill patients.
Rikisha to Rapid Transit: Urban Public Transport Systems and Policy in Southeast Asia examines the historical development of urban public transport systems and policy in Southeast Asia. The focus is on the passenger transport sector of the urban economy and the dilemmas facing decision-makers with regard to the choice of technology and organization. The prime target of the monograph is the development studies field in which urban public transport has been a neglected topic. The book is organized into three parts. Part 1 assesses Western, Japanese, and overseas Chinese models and their relevance to decision-making in Southeast Asia. Part 2 examines the evolution of transport systems and policy in five capitals (Singapore, Bangkok, Jakarta, Manila, and Kuala Lumpur) and several provincial cities (Penang, Surabaya, Davao City, Chiang Mai, Baguio and Metro Cebu). Part 3 brings out the implications of this study for theory and practice. The argument is structured in this way in order to preserve the historical sequence which will become progressively clearer as the study unfolds, particularly as there is ""a very positive indication...that the transport situation in cities results as much from historical development as from the interaction of forces currently at play.

Data matching (also known as record or data linkage, entity resolution, object identification, or field matching) is the task of identifying, matching and merging records that correspond to the same entities from several databases or even within one database. Based on research in various domains including applied statistics, health informatics, data mining, machine learning, artificial intelligence, database management, and digital libraries, significant advances have been achieved over the last decade in all aspects of the data matching process, especially on how to improve the accuracy of data matching, and its scalability to large databases. Peter Christen’s book is divided into three parts: Part I, “Overview”, introduces the subject by presenting several sample applications and their special challenges, as well as a general overview of a generic data matching process. Part II, “Steps of the Data Matching Process”, then details its main steps like pre-processing, indexing, field and record comparison, classification, and quality evaluation. Lastly, part III, “Further Topics”, deals with specific aspects like privacy, real-time matching, or matching unstructured data. Finally, it briefly describes the main features of many research and open source systems available today. By providing the reader with a broad range of data matching concepts and techniques and touching on all aspects of the data matching process, this book helps researchers as well as students specializing in data quality or data matching aspects to familiarize themselves with recent research advances and to identify open research challenges in the area of data matching. To this end, each chapter of the book includes a final section that provides pointers to further background and research material. Practitioners will better understand the current state of the art in data matching as well as the internal workings and limitations of current systems. Especially, they will learn that it is often not feasible to simply implement an existing off-the-shelf data matching system without substantial adaption and customization. Such practical considerations are discussed for each of the major steps in the data matching process.
