Defending the Digital Frontier

Second Edition

"The book recognizes, and correctly characterizes, digital security according to one of the fundamental tenets of IT governance: security, like IT governance, is a management issue, not a technical one. This book takes a very practical approach to a critical issue, and provides executive management with sound, cost-effective techniques grounded in business realities. Management and the C-suite will do well to keep these techniques in mind when formulating IT strategies that are aligned with and support business goals."

"Ernst & Young has done a superb job in demonstrating why the integrity of Digital Information Systems is fundamental to success. The authors show that protecting computers from attack is only a small part of this task. This book focuses on handling systemic risk and complexity--the inevitable problems that arise when you integrate computerized information systems with human activity systems: namely the company itself, customers, suppliers, competitors, as well as the broader political and regulatory environment. I can recommend it as essential reading to all senior executives."
--Ian Angell
Professor of Information Systems, London School of Economics

"The CBI considers security of information to be a major issue for individuals and businesses in the growing digital world. This book makes clear, that the key to success in this new environment is in using technology effectively--technology cannot make a badly organised business good, but it can make agood business better. Ernst & Young has identified critical organisational and management processes that global companies need to implement to ensure that technology effectively secures information assets that are at the heart of today's economy."

Ausgehend von der Theorie und den Protokollen der Quantenkryptografie werden in dem Band die Servicequalitaten vorgestellt, die angesichts der aktuellen technischen Moeglichkeiten erreichbar sind. Unter Berucksichtigung wenig beachteter Gesichtspunkte der Kryptoanalyse diskutiert der Autor die erreichbare Sicherheit und untersucht die Moeglichkeiten des Quantencomputing. Anhand praxisnaher Aufgaben koennen Leser ihr Wissen vertiefen und lernen, die Techniken kritisch zu bewerten. Mit Programmieranleitung fur Simulationsversuche auf dem eigenen Rechner.

Industrial cyber-physical systems operate simultaneously in the physical and digital worlds of business and are now a cornerstone of the fourth industrial revolution. Increasingly, these systems are becoming the way forward for academics and industrialists alike. The very essence of these systems, however, is often misunderstood or misinterpreted. This book thus sheds light on the problem areas surrounding cyber-physical systems and provides the reader with the key principles for understanding and illustrating them. Presented using a pedagogical approach, with numerous examples of applications, this book is the culmination of more than ten years of study by the Intelligent Manufacturing and Services Systems (IMS2) French research group, part of the MACS (Modeling, Analysis and Control of Dynamic Systems) research group at the CNRS. It is intended both for engineers who are interested in emerging industrial developments and for master's level students wishing to learn about the industrial systems of the future.

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.
