pciWhen I first received this book from Syngress I was very excited. I knew nothing about PCI compliance — other than it was big ticket item and everyone processing Visa transactions was affected in some way because of it. I can honestly say that I tore through this book and didn’t put it down until I reached chapter 13. I was completely wrapped up in it as it was something I knew nothing about and wanted to know more!

Chapters 1 through 3 introduce you to the concepts behind PCI compliance including what it is and who needs to comply. These chapters really set the stage for what the rest of the book has to offer the reader.

Chapter 4 provides a technology overview of firewalls, intrusion systems, antivirus solutions, and common system default settings. Personally I felt that Chapter 4 was filler content just to add a chapter. It may, however, serve as a good reference for those in management roles who do not have “hands-on” interaction with the architecture of their environment.

Chapter 5 explains how to go about protecting your cardholder data as dictated by PCI requirements 3 & 4. This is a great chapter for anyone new to securing infrastructure to meet the requirements of a PCI audit. The authors also provide a fantastic section entitled “The Absolute Essentials” which offers suggestions on the minimum protection you can employ to protect your cardholder data.

Chapter 6 was by far my most favorite chapter and Syngress has offered it as a free download from their website. Many of you know what I do for a living and know how important understanding logging and requirements for logging is for my day-to-day duties. This chapter focuses around PCI Requirement 10 which details how you must handle the log data collected in your PCI environment. As soon as I started reading this chapter I knew that Dr. Anton Chuvakin had written this section of the book, or at least had a heavy insight into its direction. This chapter alone makes the book worth its weight in gold.

Chapter 7 details the importance of access control in your PCI environment. For obvious reasons, access to your cardholder data must be recorded and checked with a fine tooth comb. User privileges, authentication, authorization, and user education is also covered in this chapter. This chapter goes further to provide examples of ensuring your Windows, Unix/Linux, and Cisco infrastructure meet PCI requirements.

Chapter 8 explains how to leverage vulnerability management solutions to meet the requirements outlined in sections 5, 6, and 11 of the PCI requirement. The authors also provide two very good case studies to help the reader put things into perspective.

Chapter 9 focusses on the monitoring and testing of your environment. The authors are quick to point out that monitoring and testing must continue even after the audit in order to ensure you remain compliant.

Chapter 10 details how to drive your PCI project from the business side in order to ensure you accomplish your objectives. Suggestions are provided on budgeting time and resources, keeping staff in the loop, and justifying the business case to your executive team. The authors also offer a step-by-step “checklist” for ensuring your project runs smoothly and that all of your bases are covered.

Chapter 11 explains the various responsibilities within the organization for ensuring the PCI project succeeds. One of the key things to take away from this chapter is the role of the Incident Response team and its need to understand the requirements of PCI compliance.

Chapter 12 is a really good “eye-opener” that prepares you for the failure of your first audit. The key thing to take away from this is chapter is to not blame the auditor the same way you shouldn’t blame a referee in sports. They’re simply there to do their job to the best of their ability. If you have a problem with the way they are doing their job, bring it up with their superior. Perhaps their decision will get overturned?

Chapter 13 brings you into a “OK, now what?” phase. This chapter provides a detailed overview of the various requirements and breaks each requirement into “Policy Checks” and “Hands-on Assessments” sections. The policy checks discuss policies that should be reviewed to verify that they are up-to-date and the hands-on assessments sections give ideas on testing these policies. The beauty part is that the authors suggest open source solutions to help you protect your PCI compliant investment.

I give this book 5 stars as it is the best PCI reference I have found on the market. Everything I found in this book will allow me to understand the compliance requirements of my existing customers, their process, and their overall goals. Hats off to the entire team of authors.

windowsforensicThere are very few books on the topic of Windows Forensic Analysis and Harlan Carvey has taken it upon himself to provide the security community with a guided tour of the inner workings of Microsoft operating systems. As Microsoft does not yet offer a “forensic” track in it’s training offerings most forensic knowledge of Windows comes from on the job experience or tool specific training offered by a vendor.

This book begins by leading you through the collection of evidence. The author provides you with examples of collecting data from live running systems using commercial tools, tools native to Windows, and advanced perl scripts which are provided on the accompanying DVD. Locard’s Exchange Principle, a principle unknown to me prior to reading this book, is explained in great detail and is reference throughout the book. The concept is further demonstrated in an example using my favorite security tool, Netcat. People who respond to incidents need to know what to look for. Harlan dives deep into the key items of interest and explains how to pay special attention to volatile information such as system time, network connections, clipboard contents, and mapped drives, to name a few.

Once you have collected your data the author moves into specific chapters on how to analyze and make sense of it. Harlan does a fantastic job of explaining how to analyze memory (dumping the memory, analyzing crash dumps, reading through memory, etc.), analyzing the registry (tracking user activity, explaining how processes autostart from registry entries, etc.), analyzing windows files (working with event logs, common document formats, alternate data streams, etc.), analyzing executable files (static and dynamic analysis), and finally rootkits (detecting and preventing).

On the cover of the book the author has a quote by Troy Larson, Senior Forensic Investigator of Microsoft’s IT Security Group which states:

“The Registry Analysis chapter alone is worth the price of the book.”

When I first received the book I thought “Wow, that’s a glowing recommendation” and upon reading the book cover to cover I couldn’t agree more. I have yet to see a book which takes you through the intricacies of the Windows Registry in such a way that I, being a Linux person, could easily relate to.

The rootkit chapter was a little light on content but the rest of the book makes up for it. There are books out there dedicated to rootkits and I wouldn’t expect the author to provide a book that explains everything about everything and still expect people to be able to carry it with them.

The accompanying DVD contains the scripts mentioned in the book, some videos explaining the use of some tools, as well as a bonus folder that contains … well I’ll let you buy the book to find out what cool tools are provided.

This book should be on every analysts shelf whether they perform Windows forensic analysis as part of their role, or think that they might be called upon to do so in a pinch. I also think that this book is a fantastic supplement to any Microsoft training and any security training you may receive in the future.

I give this book 4.5 stars as it is easy to read and kept my interest throughout the entire book.

Do yourself a favor and pick up this book today.

The good people at Syngress, with the help of Harlan Carvey and Jeremiah Grossman, have sent me too new books to review. I can’t wait to tear into both of these titles!

windowsforensicWindows Forensic Analysis Including DVD Toolkit

From Syngress:

One thing that many computer forensic examiners have noticed is an over reliance by investigators on what forensic analysis tools are telling them, without really understanding where this information is coming from or how it is being created or derived.

The age of “Nintendo forensics” (i.e., loading an acquired image into a forensic analysis application and pushing a button) is over. As analysts and examiners, we can no longer expect to investigate a case in such a manner. Cybercrime has increased in sophistication, and investigators need to understand what artifacts are available on a system, as well as how those artifacts are created and modified. With this level of knowledge, we come to understand that the absence of an artifact is itself an artifact. In addition, more and more presentations and material are available regarding anti-forensics, or techniques used to make forensic analysis more difficult. Moreover, there have been presentations at major conferences that discuss the anti-forensic technique of using the forensic analysts’ training and tools against them.

This book is intended to address the need for a more detailed, granular level of understanding. It attempts not only to demonstrate what information is available to the investigator on both a live Windows system and in an acquired image but also to provide information on how to locate additional artifacts that may be of interest.

xssCross Site Scripting Attacks: Xss Exploits and Defense

From Syngress:

Cross Site Scripting Attacks starts by defining the terms and laying out the ground work. It assumes that the reader is familiar with basic web programming (HTML) and JavaScript. First it discusses the concepts, methodology, and technology that makes XSS a valid concern. It then moves into the various types of XSS attacks, how they are implemented, used, and abused. After XSS is thoroughly explored, the next part provides examples of XSS malware and demonstrates real cases where XSS is a dangerous risk that exposes internet users to remote access, sensitive data theft, and monetary losses. Finally, the book closes by examining the ways developers can avoid XSS vulnerabilities in their web applications, and how users can avoid becoming a victim. The audience is web developers, security practitioners, and managers.

counter_hack I’ve just hit page 302 of Counter Hack Reloaded: A Step-by-Step Guide to Computer Attacks and Effective Defenses (2nd Edition) and I must say that this is one of the few books on ‘hacking’ that has kept my interest. I’ve read similar books in the past but none have actually been written in a manner that keeps the reader wanting to read cover-to-cover instead of using the book for reference material. I’ll post a full review when I’m done.

Interim Rating – 4/5 Stars
