The purpose of this book is to discuss, in depth, the current state of research and practice in database security, to enable readers to expand their knowledge. The book brings together contributions from experts in the field throughout the world. Database security is still a key topic in mist businesses and in the public sector, having implications for the whole of society.

This book documents progress and presents a broad perspective of recent developments in database security. It also discusses in depth the current state-of-the-art in research in the field. A number of topics are explored in detail including: current reseearch in database security and the state of security controls in present commercial database systems. Database Security IX will be essential reading for advanced students working in the area of database security research and development in for industrial researchers in this technical area.

This book aims to discuss in depth the current state of research and practice in database security. It documents progress and provides researchers and students with a broad perspective of recent developments in what is recognised as a key topic in business and in the public sector.

New technology is always evolving and companies must have appropriate security for their business to be able to keep up-to-date with the changes. With the rapid growth in internet and www facilities, database security will always be a key topic in business and in the public sector and has implications for the whole of society. Database Security Volume XII covers issues related to security and privacy of information in a wide range of applications, including: Electronic Commerce Informational Assurances Workflow Privacy Policy Modeling Mediation Information Warfare Defense Multilevel Security Role-based Access Controls Mobile Databases Inference Data Warehouses and Data Mining. This book contains papers and panel discussions from the Twelfth Annual Working Conference on Database Security, organized by the International Federation for Information Processing (IFIP) and held July 15-17, 1998 in Chalkidiki, Greece. Database Security Volume XII will prove invaluable reading for faculty and advanced students as well as for industrial researchers and practitioners working in the area of database security research and development.

The current state of database security research and practice is explored in this volume. Contributions are sourced from a wide range of international specialists involved in the field, ensuring a comprehensive cross-fertilization of ideas. Progress achieved in the following areas is given particular emphasis: user groups and roles; database architecture; inference analysis and control; database models; queries, updates and transactions; policy modelling; access control and application design. Invited papers provide a perspective on the implications of security in health care systems, plus current trends in database technology and their impact on security concepts.

Many commercial and defense applications require a database system that protects data of different sensitivities while still allowing users of different clearances to access the system. This book is a collection of papers covering aspects of the emerging security technology for multilevel database systems. It contains reports on such landmark systems as SeaView, LDV, ASD, Secure Sybase, the UNISYS secure distributed system, and the secure entity-relationship system GTERM. Much of the research is concerned with the relational model, although security for the entity-relationship and object-oriented models of data are also discussed. Because the field is so new, it has been extremely difficult to learn about the research going on in this area, until now. This book will be invaluable to researchers and system designers in database systems and computer security. It will also be of interest to data users and custodians who are concerned with the security of their information. This book can also be used as a text for an advanced topics course on computer security in a computer science curriculum.
