Windows Forensics and Incident Recovery

Description

As long as networks of Microsoft Windows systems are managed,

administered, and used by people, security incidents will occur. Windows

systems are highly pervasive throughout the entire computing infrastructure,

from home and school systems, to high-end e-commerce sites. In contrast to

this pervasiveness, information regarding conducting effective incident

response and forensic audit activities on Windows systems is limited. While

there are many security books available, none focus specifically on Windows

security. There are also resources available online, but they are scattered and

often too general. This book is a compilation of all the information currently

available on this subject. It is for anyone who manages or administers Windows

systems (including home users) and needs to know how to react when they

suspect that an incident has occurred. It guides the reader through

information, tools, and techniques that are required to conduct incident

response or a live forensics audit activities. By providing the necessary

background for understanding how incidents occur and how data can be

hidden on compromised systems, the reader will have a better understanding of

the "whys" and "hows" of incident response and forensic audit activities. *It is

important to note that regulatory issues are also pushing organizations toward

better security and incident preparedness policies.


Features

The first book completely devoted to this important part of security in a Windows environment.

° A one-stop shop for Microsoft Windows sys admins to find technical security information.

° The CD-Rom contains unique tools the author has written (code, network packet captures, and the results of a capture using the tools) and research methodologies that the reader can implement immediately.

° Provides strong examples and case studies to enhance understanding.

-Mark Burnett, security consultant and author

  • The first book to focus on forensics and incident recovery in a Windows environment

  • Teaches through case studies and real world-examples

  • Companion CD contains unique tools developed by the author.

  • Covers Windows Server 2003, Windows 2000, Windows NT, and Windows XP

If you're responsible for protecting Windows systems, firewalls and anti-virus aren't enough. You also need to master incident response, recovery, and auditing. Leading Windows security expert and instructor Harlan Carvey offers a start-to-finish guide to the subject: everything administrators must know to recognize and respond to virtually any attack.

Drawing on his widely acclaimed course, Carvey uses real-world examples to cover every significant incident response, recovery, and forensics technique. He delivers a complete incident response toolset that combines today's best open source and freeware tools, his own exclusive software and scripts, and step-by-step instructions for using them. This book's tools and techniques apply to every current and professional version of Windows: NT, 2000, XP, and Windows Server 2003. Coverage includes:

  • Developing a practical methodology for responding to potential attacks

  • Preparing your systems to prevent and detect incidents

  • Recognizing the signatures of an attack-in time to act

  • Uncovering attacks that evade detection by Event Viewer, Task Manager, and other Windows GUI tools

  • Using the Forensic Server Project to automate data collection during live investigations

  • Analyzing live forensics data in order to determine what occurred

CD-ROM INCLUDED

CD-ROM contains incident response and forensics toolkit code developed by the author, sample network packet captures, as well as data collected from compromised systems using the Forensic Server Project. You can also access Carvey's website at http://www.windows-ir.com for code samples, updates, and errata.

Acknowledgments

I'd like to start by thanking Larry Leibrock and Jay Heiser for getting me started down this road. Several years ago, I had developed a 2-day, hands-on incident response course for Windows 2000, and Larry provided me with my initial opportunity to teach it at the University of Texas in Austin. This book began its life as the presentation for the incident response course. I had done a technical review of Jay and Warren Kruse's computer forensics book, and Jay provided my name to his former editor as someone who may be interested in writing a book on the subject of Windows security.

Karen Gettman offered me the opportunity to write this book, and I decided to take it. I'd had articles published, but I'd never written a book. Karen and her assistant, Elizabeth Zdunich, kept me on track throughout this process.

I'd like to thank several of the reviewers as well. Of all of the reviewers who've been involved in this process, I'd like to recognize Jennifer Kolde, Mike Lyman, and Jason Chan for their efforts and input. The reviews from these three individuals provided valuable constructive criticism regarding the content and structure of the book. I can't say that I followed all the advice they provided, but I did read and consider everything they said thoroughly. With their help and insight, I didn't feel as if I were working on this book alone. Thanks, guys, for your time and effort. And Jen, thanks for indulging me all those time I'd email you with thoughts about your comments. Those exchanges gave me even more insight into to the content of the book, as well as the subject of incident response on Windows systems, in general.

Finally, and most importantly, I'd like to thank Terri Dougherty. I've written a book, and yet I can't seem to find the words to express my gratitude for your support throughout this process. Thank you. I owe you a debt that I will be repaying for a long time.

Author

Harlan Carvey¿s interest in computer and information security began while he was an officer in the U.S. military, during which time he earned his master¿s degree in Electrical Engineering. After leaving military service, he began working in the field of commercial and government information security consulting, performing vulnerability assessments and penetration tests. While employed at one company, he was the sole developer of a program for collecting security-specific information (i.e., Registry entries, file information, configuration settings, etc.) from Windows NT systems during vulnerability assessments. The purpose of the product was to overcome shortfalls in commercial scanning products and provide more valuable information to the customer. Harlan has also done considerable work in the area of incident response and forensics, performing internal and external investigations. He has also written a number of proof-of- concept tools for educating users in such topics as Windows null sessions, file signature analysis, and the retrieval of metadata from a variety of files.

Harlan¿s experience with computers began in the early ¿80s, with a Timex-Sinclair 1000. Around that time, he was learning to program BASIC on an Apple IIe. From there, he moved on to computers such as the Epson QX-10 and the TRS-80, on which he programmed BASIC learned PASCAL, using the TurboPASCAL compiler. Since then, he¿s worked with SunOS and Solaris systems, as well as various versions of DOS and Windows, OS/2, and Linux.

Harlan has presented at Usenix, DefCon9, Black Hat, GMU2003 on various topics specific to issues on Windows platforms, such as data hiding. He has had articles published in the Information Security Bulletin and on the SecurityFocus web site.
