Introduction to Information Security

A Strategic-Based Approach

Most introductory texts provide a technology-based survey of methods and techniques that leaves the reader without a clear understanding of the interrelationships between methods and techniques. By providing a strategy-based introduction, the reader is given a clear understanding of how to provide overlapping defenses for critical information. This understanding provides a basis for engineering and risk-management decisions in the defense of information. Information security is a rapidly growing field, with a projected need for thousands of professionals within the next decade in the government sector alone. It is also a field that has changed in the last decade from a largely theory-based discipline to an experience-based discipline. This shift in the field has left several of the classic texts with a strongly dated feel. Provides a broad introduction to the methods and techniques in the field of information security Offers a strategy-based view of these tools and techniques, facilitating selection of overlapping methods for in-depth defense of information Provides very current view of the emerging standards of practice in information security

Introduction to Information Quality

This is a sound textbook for Information Technology and MIS undergraduate students, and MBA graduate students and all professionals looking to grasp a fundamental understanding of information quality. The authors performed an extensive literature search to determine the Fundamental Topics of Data Quality in Information Systems. They reviewed these topics via a survey of data quality experts at the International Conference on Information Quality held at MIT. The concept of data quality is assuming increased importance. Poor data quality affects operational, tactical and strategic decision-making, and yet error rates of up to 70%, with 30% typical are found in practice (Redman). Data that is deficient leads to misinformed people, who in turn make bad decisions. Poor quality data impedes activities such as re-engineering business processes and implementing business strategies. Poor data quality has contributed to major disasters in the federal government, NASA, Information Systems, Federal Bureau of Investigation, and most busineses. The diverse uses of data and the increased sharing of data that has arisen as a result of the widespread introduction of data warehouses have exacerbated deficiencies with the quality of data (Ballou). In addition, up to half the cost of creating a data warehouse is attributable to poor data quality. The management of data quality so as to ensure the quality of information products is examined in Wang. The purpose of this book is to alert our IT-MIS-Business professionals to the pervasiveness and criticality of data quality problems. The secondary agenda is to begin to arm the students with approaches and the commitment to overcome these problems. The current authors have a combined list of over 200 published papers on data and information quality.

Introduction to Information Behaviour

This landmark textbook is an essential primer for students and practitioners interested in information seeking, needs and behaviour, user studies and information literacy. Introduction to Information Behaviour uses a combination of theory and practical context to map out what information behaviour is and what we currently know about it, before addressing how it can be better understood in the future. Nigel Ford argues that new understandings of information behaviour research may help maximise the quality and effectiveness of the way information is presented, sought, discovered, evaluated and used. The book introduces the key concepts, issues and themes of information behaviour, illustrates them using key research studies, and provides a clear path through the complex maze of theories and models. The book is structured to move from the basics to the more complex and employs the pedagogical device of “THINK” boxes which invite the reader to think about concepts as they are introduced in order to consolidate their understanding before moving on. Case studies are included throughout the text and each chapter concludes with a round-up of what has been covered, highlighting the implications for professional information practice. The key topics covered include: Defining information behaviour and why is it useful to know about it Information needs Information seeking and acquisition Collaborative information behaviour Factors affecting information behaviour Models and theories of information behaviour Research approaches and methodologies Designing information systems The future trajectory of information behaviour research and practice. Readership: This book will be core reading for students around the world, particularly those on library and information science courses. It will also be of interest to practitioners and professional information users, providers and developers.

Introduction to Information Visualization

Information Visualization is a relatively young field that is acquiring more and more concensus in both academic and industrial environments. 'Information Visualization' explores the use of computer-supported interactive graphical representations to explain data and amplify cognition. It provides a means to comunicate ideas or facts about the data, to validate hypotheses, and facilitates the discovery of new facts via exploration. This book introduces the concepts and methods of Information Visualization in an easy-to-understand way, illustrating how to pictorially represent structured and unstructured data, making it easier to comprehend and interpret. Riccardo Mazza focuses on the human aspects of the process of visualization rather than the algorithmic or graphic design aspects.

Codes: An Introduction to Information Communication and Cryptography

Many people do not realise that mathematics provides the foundation for the devices we use to handle information in the modern world. Most of those who do know probably think that the parts of mathematics involvedare quite ‘cl- sical’, such as Fourier analysis and di?erential equations. In fact, a great deal of the mathematical background is part of what used to be called ‘pure’ ma- ematics, indicating that it was created in order to deal with problems that originated within mathematics itself. It has taken many years for mathema- cians to come to terms with this situation, and some of them are still not entirely happy about it.
