"The book itself is a diagram of clarification, containing hundreds of examples of work by those who favor the communication of information over style and academic postulation—and those who don't. Many blurbs such as this are written without a thorough reading of the book. Not so in this case. I read it and love it. I suggest you do the same." —Richard Saul Wurman «This handsome, clearly organized book is itself a prime example of the effective presentation of complex visual information.» —eg magazine «It is a dream book, we were waiting for…on the field of information. On top of the incredible amount of presented knowledge this is also a beautifully designed piece, very easy to follow…» —Krzysztof Lenk, author of Mapping Websites: Digital Media Design «Making complicated information understandable is becoming the crucial task facing designers in the 21st century. With Designing Information, Joel Katz has created what will surely be an indispensable textbook on the subject.» —Michael Bierut «Having had the pleasure of a sneak preview, I can only say that this is a magnificent achievement: a combination of intelligent text, fascinating insights and – oh yes – graphics. Congratulations to Joel.» —Judith Harris, author of Pompeii Awakened: A Story of Rediscovery Designing Information shows designers in all fields – from user-interface design to architecture and engineering – how to design complex data and information for meaning, relevance, and clarity. Written by a worldwide authority on the visualization of complex information, this full-color, heavily illustrated guide provides real-life problems and examples as well as hypothetical and historical examples, demonstrating the conceptual and pragmatic aspects of human factors-driven information design. Both successful and failed design examples are included to help readers understand the principles under discussion.

Your expert guide to information security As businesses and consumers become more dependent on complex multinational information systems, the need to understand and devise sound information security systems has never been greater. This title takes a practical approach to information security by focusing on real-world examples. While not sidestepping the theory, the emphasis is on developing the skills and knowledge that security and information technology students and professionals need to face their challenges. The book is organized around four major themes: * Cryptography: classic cryptosystems, symmetric key cryptography, public key cryptography, hash functions, random numbers, information hiding, and cryptanalysis * Access control: authentication and authorization, password-based security, ACLs and capabilities, multilevel and multilateral security, covert channels and inference control, BLP and Biba's models, firewalls, and intrusion detection systems * Protocols: simple authentication protocols, session keys, perfect forward secrecy, timestamps, SSL, IPSec, Kerberos, and GSM * Software: flaws and malware, buffer overflows, viruses and worms, software reverse engineering, digital rights management, secure software development, and operating systems security Additional features include numerous figures and tables to illustrate and clarify complex topics, as well as problems-ranging from basic to challenging-to help readers apply their newly developed skills. A solutions manual and a set of classroom-tested PowerPoint(r) slides will assist instructors in their course development. Students and professors in information technology, computer science, and engineering, and professionals working in the field will find this reference most useful to solve their information security issues. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department. An Instructor Support FTP site is also available.

This fully updated edition demonstrates how businesses can succeed in creating a new culture of information management compliance (IMC) by incorporating an IMC philosophy into a corporate governance structure. Expert advice and insight reveals the proven methodology that adopts the principles, controls, and discipline upon which many corporate compliance programs are built and explains how to apply this methodology to develop and implement IMC programs that anticipate problems and take advantage of opportunities. Plus, you'll learn how to measure information management compliance through the use of auditing and monitoring, following the proper delegation of program roles and components, and creating a culture of information management awareness.

This book introduces policy, government, and security professionals to the concept of “information warfare,” covering its evolution over the last decade and its developments among such economic and political giants as China, Russia, Japan, India, and Singapore. The text describes various conceptions of information warfare, along with how they function in military, diplomatic, political, and economic contexts. Recent notable cyber attacks are analyzed, the challenges faced by countries who fail to secure their cyberspace (Japan, the US, etc.) are enumerated, and ways to distinguish between cybercrime, cyberwarfare, and cyberterrrorism are discussed.

The essential guide to effective IG strategy and practice Information Governance is a highly practical and deeply informative handbook for the implementation of effective Information Governance (IG) procedures and strategies. A critical facet of any mid- to large-sized company, this “super-discipline” has expanded to cover the management and output of information across the entire organization; from email, social media, and cloud computing to electronic records and documents, the IG umbrella now covers nearly every aspect of your business. As more and more everyday business is conducted electronically, the need for robust internal management and compliance grows accordingly. This book offers big-picture guidance on effective IG, with particular emphasis on document and records management best practices. Step-by-step strategy development guidance is backed by expert insight and crucial advice from a leading authority in the field. This new second edition has been updated to align with the latest practices and regulations, providing an up-to-date understanding of critical IG concepts and practices. Explore the many controls and strategies under the IG umbrella Understand why a dedicated IG function is needed in today’s organizations Adopt accepted best practices that manage risk in the use of electronic documents and data Learn how IG and IT technologies are used to control, monitor, and enforce information access and security policy IG strategy must cover legal demands and external regulatory requirements as well as internal governance objectives; integrating such a broad spectrum of demands into workable policy requires a deep understanding of key concepts and technologies, as well as a clear familiarity with the most current iterations of various requirements. Information Governance distills the best of IG into a primer for effective action.

The Growing Imperative Need for Effective Information Security Governance With monotonous regularity, headlines announce ever more spectacular failures of information security and mounting losses. The succession of corporate debacles and dramatic control failures in recent years underscores the necessity for information security to be tightly integrated into the fabric of every organization.

What are we to make of the information society? Many prominent theorists have argued it to be the most profound and comprehensive transformation of economy, culture and politics since the rise of the industrial way of life in the 18th century. Some saw its arrival in a positive light, where the dreams of democracy, of ‘connectivity’ and ‘efficiency’ constituted a break with the old ways. But other thinkers viewed it more in terms of the recurrent nightmare of capitalism, where the processes of exploitation, commodification and alienation are given much freer rein than ever before. In this book Robert Hassan, a prominent theorist in new media and its effects, analyses and critically appraises these positions and forms them into a coherent narrative to illuminate the phenomenon. Surveying the works of major information society theorists from Daniel Bell to Nicholas Negroponte, and from Vincent Mosco to Manuel Castells, The Information Society is an invaluable resource for understanding the nature of the information society—as well as the meta-processes of neoliberal globalisation and the revolution in information technologies that made it possible.
