An oft-repeated adage among telecommunication providers goes, “There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can’t do all ve, at least do the rst three. ” Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

This handbook is an authoritative, comprehensive reference on optical networks, the backbone of today’s communication and information society. The book reviews the many underlying technologies that enable the global optical communications infrastructure, but also explains current research trends targeted towards continued capacity scaling and enhanced networking flexibility in support of an unabated traffic growth fueled by ever-emerging new applications. The book is divided into four parts: Optical Subsystems for Transmission and Switching, Core Networks, Datacenter and Super-Computer Networking, and Optical Access and Wireless Networks. Each chapter is written by world-renown experts that represent academia, industry, and international government and regulatory agencies. Every chapter provides a complete picture of its field, from entry-level information to a snapshot of the respective state-of-the-art technologies to emerging research trends, providing something useful for the novice who wants to get familiar with the field to the expert who wants to get a concise view of future trends.

This book analyses the compatibility of data retention in the UK with the European Convention on Human Rights (ECHR). The increase in the use of modern technology has led to an explosion of generated data and, with that, a greater interest from law enforcement and intelligence agencies. In the early 2000s, data retention laws were introduced into the UK, and across the European Union (EU). This was met by domestic challenges before national courts, until a seminal ruling by the Court of Justice in the European Union (CJEU) ruled that indiscriminate data retention was incompatible with EU law. Since then, however, the CJEU has revised its position and made certain concessions, particularly under the guise of national security. This book focuses on data retention in the UK with the principal aim of examining compatibility with the ECHR. This is explored through a variety of ways including providing an account of democracy and why secret surveillance poses a threat to it, a history of data retention, assessing the seriousness that data retention poses to fundamental rights, the collection of rights that are affected by data retention which are crucial for a functioning democracy, the implications of who can be obligated to retain (and what to retain), the idea that data retention is a form of surveillance and ultimately, with all things considered, whether this is compatible with the ECHR. The work will be an invaluable resource for students, academics, researchers and policy-makers working in the areas of privacy, human rights law and surveillance.

Internet usage has become a facet of everyday life, especially as more technological advances have made it easier to connect to the web from virtually anywhere in the developed world.

The Handbook of Research on Modern Cryptographic Solutions for Computer and Cyber Security identifies emergent research and techniques being utilized in the field of cryptology and cyber threat prevention. Featuring theoretical perspectives, best practices, and future research directions, this handbook of research is a vital resource for professionals, researchers, faculty members, scientists, graduate students, scholars, and software developers interested in threat identification and prevention.

As you read this, your computer is in jeopardy of being hacked and your identity being stolen. Read this book to protect yourselves from this threat. The world’s foremost cyber security experts, from Ruby Lee, Ph.D., the Forrest G. Hamrick professor of engineering and Director of the Princeton Architecture Laboratory for Multimedia and Security (PALMS) at Princeton University; to Nick Mankovich, Chief Information Security Officer of Royal Philips Electronics; to FBI Director Robert S. Mueller III; to Special Assistant to the President Howard A. Schmidt, share critical practical knowledge on how the cyberspace ecosystem is structured, how it functions, and what we can do to protect it and ourselves from attack and exploitation. The proliferation of social networking and advancement of information technology provide endless benefits in our living and working environments. However, these benefits also bring horrors in various forms of cyber threats and exploitations. Advances in Cyber Security collects the wisdom of cyber security professionals and practitioners from government, academia, and industry across national and international boundaries to provide ways and means to secure and sustain the cyberspace ecosystem. Readers are given a first-hand look at critical intelligence on cybercrime and security—including details of real-life operations. The vast, useful knowledge and experience shared in this essential new volume enables cyber citizens and cyber professionals alike to conceive novel ideas and construct feasible and practical solutions for defending against all kinds of adversaries and attacks. Among the many important topics covered in this collection are building a secure cyberspace ecosystem; public–private partnership to secure cyberspace; operation and law enforcement to protect our cyber citizens and to safeguard our cyber infrastructure; and strategy and policy issues to secure and sustain our cyber ecosystem.
