You can't succeed in the field of computer forensics without hands-on practiceand you can't get hands-on practice without real forensic data. The solution: Real Digital Forensics. In this book, a team of world-class computer forensics experts walks you through six detailed, highly realistic investigations and provides a DVD with all the data you need to follow along and practice.
From binary memory dumps to log files, this DVD's intrusion data was generated by attacking live systems using the same tools and methods real-world attackers use. The evidence was then captured and analyzed using the same tools the authors employ in their own investigations. This book relies heavily on open source tools, so you can perform virtually every task without investing in any commercial software.
You'll investigate environments ranging from financial institutions to software companies and crimes ranging from intellectual property theft to SEC violations. As you move step by step through each investigation, you'll discover practical techniques for overcoming the challenges forensics professionals face most often.
Inside, you will find in-depth information on the following areas:
Responding to live incidents in both Windows and Unix environments
Determining whether an attack has actually occurred
Assembling a toolkit you can take to the scene of a computer-related crime
Analyzing volatile data, nonvolatile data, and files of unknown origin
Safely performing and documenting forensic duplications
Collecting and analyzing network-based evidence in Windows and Unix environments
Reconstructing Web browsing, e-mail activity, and Windows Registry changes
Tracing domain name ownership and the source of e-mails
Duplicating and analyzing the contents of PDAs and flash memory devices
The accompanying DVD contains several gigabytes of compressed data generated from actual intrusions. This data mirrors what analysts might find in real investigations and allows the reader to learn about forensic investigations in a realisticsetting.

PrefacePreface
Our Purpose and Approach
Welcome to the book namedReal Digital Forensics. When we conceived this book, we wanted to give forensic investigators more than words to learn new skills. Many people express to us in our classes and speaking engagements a simple sentence we have heard hundreds of times: "How do I get into the field of computer forensics?" In our opinion, you cannot learn forensics unless you have hands-on practical experience. This brings up a more important question we usually hear next: "How do I get my hands on data to gain that experience?" This question is much more difficult to answer because the only data most people have to practice with comes from real casesand we all know that our clients do not want their data disseminated for learning tools! Therefore, it is difficult for most people to find data to practice with in order to sharpen their computer forensic skills. To answer this second question, we decided to publish this book with a DVD containing realistic evidence collected from several fictitious scenarios for the sole purpose of teaching the computer forensic tradecraft.
Most of the scenarios you will find throughout this book are very similar to types of cases that we investigate every day. We used the same tools attackers use when establishing a foothold in your network, the same methods rogue employees make use of to steal your trade secrets, and the same media we typically collect when we created the evidence files found on the DVD.
