This book is targeted at senior students in any of the many branches of Information Technology, including Computer Science, Informatics and Information Systems.

It is intended to introduce the students to the operation of the research process in these subjects. It highlights the essential aspects of various research methods.

The exercises at the end of the chapters are intended to encourage students to learn from published reports; to stimulate them to think about applying each method to a research problem of their own; and to point them to related topics that were not covered in the chapter.

Digital forensics deals with the acquisition, preservation, examination, analysis and presentation of electronic evidence. Networked computing, wireless communications and portable electronic devices have expanded the role of digital forensics beyond traditional computer crime investigations. Practically every crime now involves some aspect of digital evidence; digital forensics provides the techniques and tools to articulate this evidence. Digital forensics also has myriad intelligence applications. Furthermore, it has a vital role in information assurance a" investigations of security breaches yield valuable information that can be used to design more secure systems.

Advances in Digital Forensics II describes original research results and innovative applications in the emerging discipline of digital forensics. In addition, it highlights some of the major technical and legal issues related to digital evidence and electronic crime investigations. The areas of coverage include:

• Themes and Issues in Digital Forensics
• Evidence Collecting and Handling
• Forensic Techniques
• Operating System and File System Forensics
• Network Forensics
• Portable Electronic Device Forensics
• Linux and File System Forensics
• Training, Governance and Legal Issues

This book is the second volume in the anual series produced by the International Federation for Information Processing (IFIP) Working Group 11.9 on Digital Forensics, an international community of scientists, engineers and practitioners dedicated to advancing the state of the art of research and practice in digital forensics. The bookcontains a selection of twenty-five edited papers from the First Annual IFIP WG 11.9 Conference on Digital Forensics, held at the National Center for Forensic Science, Orlando, Florida, USA in the spring of 2006.

Advances in Digital Forensics is an important resource for researchers, faculty members and graduate students, as well as for practitioners and individuals engaged in research and development efforts for the law enforcement and intelligence communities.

Martin S. Olivier is a Professor of Computer Science and co-manager of the Information and Computer Security Architectures Research Group at the University of Pretoria, Pretoria, South Africa.

Sujeet Shenoi is the F.P. Walter Professor of Computer Science and a principal with the Center for Information Security at the University of Tulsa, Tulsa, Oklahoma, USA.

Database and Application Security XV provides a forum for original research results, practical experiences, and innovative ideas in database and application security. With the rapid growth of large databases and the application systems that manage them, security issues have become a primary concern in business, industry, government and society. These concerns are compounded by the expanding use of the Internet and wireless communication technologies.

This volume covers a wide variety of topics related to security and privacy of information in systems and applications, including:

• Access control models;
• Role and constraint-based access control;
• Distributed systems;
• Information warfare and intrusion detection;
• Relational databases;
• Implementation issues;
• Multilevel systems;
• New application areas including XML.

Database and Application Security XV contains papers, keynote addresses, and panel discussions from the Fifteenth Annual Working Conference on Database and Application Security, organized by the International Federation for Information Processing (IFIP) Working Group 11.3 and held July 15-18, 2001 in Niagara on the Lake, Ontario, Canada.
