Access control is one of the fundamental services that any Data Management System should provide. Its main goal is to protect data from unauthorized read and write operations. This is particularly crucial in today's open and interconnected world, where each kind of information can be easily made available to a huge user population, and where a damage or misuse of data may have unpredictable consequences that go beyond the boundaries where data reside or have been generated. This book provides an overview of the various developments in access control for data management systems. Discretionary, mandatory, and role-based access control will be discussed, by surveying the most relevant proposals and analyzing the benefits and drawbacks of each paradigm in view of the requirements of different application domains. Access control mechanisms provided by commercial Data Management Systems are presented and discussed. Finally, the last part of the book is devoted to discussion of some of the most challenging and innovative research trends in the area of access control, such as those related to the Web 2.0 revolution or to the Database as a Service paradigm. This book is a valuable reference for an heterogeneous audience. It can be used as either an extended survey for people who are interested in access control or as a reference book for senior undergraduate or graduate courses in data security with a special focus on access control. It is also useful for technologists, researchers, managers, and developers who want to know more about access control and related emerging trends. Table of Contents: Access Control: Basic Concepts / Discretionary Access Control for Relational Data Management Systems / Discretionary Access Control for Advanced Data Models / Mandatory Access Control / Role-based Access Control / Emerging Trends in Access Control

Autorentext

Felix Naumann studied mathematics, economy, and computer sciences at the University of Technology in Berlin. After receiving his diploma in 1997 he joined the graduate school "Distributed Information Systems" at Humboldt University of Berlin. He completed his Ph.D. thesis on "Quality-driven Query Answering" in 2000. In 2001 and 2002 he worked at the IBM Almaden Research Center on topics around data integration. From 2003-2006 he was an assistant professor of information integration at the Humboldt University of Berlin. Since 2006 he has held the chair for information systems at the Hasso Plattner Institute at the University of Potsdam in Germany. He is Editor-in-Chief of the Information Systems journal. His research interests are in the areas of information integration, data quality, data cleansing, text extraction, and-of course-data profiling. He has given numerous invited talks and tutorials on the topic of the book. Melanie Herschel finished her studies of information technology atthe University of Cooperative Education in Stuttgart in 2003. She then joined the data integration group at the Humboldt University of Berlin (2003-2006), and continued her research on data cleansing and data integration at the Hasso Plattner Institute at the University of Potsdam in Germany (2006-2008). She completed her Ph.D. thesis on "Duplicate Detection in XML Data" in 2007. In 2008, she worked at the IBM Almaden Research Center, concentrating her research on data provenance. Since 2009, she pursues research on data provenance and query analysis at the database systems group at the University of Tübingen in Germany. Besides her publications and invited talks on duplicate detection and data cleansing, Melanie Herschel has also been a member of several program committees and has chaired and organized a workshop on data quality.
