Intrusion Signatures and Analysis opens with an introduction into the format of some of the more common sensors and then begins a tutorial into the unique format of the signatures and analyses used in the book. After a challenging four-chapter review, the reader finds page after page of signatures, in order by categories. Then the content digs right into reaction and responses covering how sometimes what you see isn¿t always what is happening. The book also covers how analysts can spend time chasing after false positives. Also included is a section on how attacks have shut down the networks and web sites of Yahoo, and E-bay and what those attacks looked like. Readers will also find review questions with answers throughout the book, to be sure they comprehend the traces and material that has been covered.
Chapter 1 introduces the reader to Analysis of Logs (including Snort, Tcpdump, and Syslog), IDS, and Firewalls. Even being a quick review, it is quite useful, though.Chapter 2 explains the way the cases are studied.
The covered vulnerabilities and attacks include:- Internet Security Threats- Routers and Firewalls Attacks- IP Spoofing- Networks Mapping and Scanning- Denial of Service- Trojans- Assorted Exploits- Buffer Overflows- IP Fragmentation- False Positives- Crafted Packets
At the bottom line, this is one of the 5 best computer security books I ever read. Even for non experts, the book can be a valuable tool to improve the understanding on this field.Try it.
It's great to learn intrusion detection, packet analysis, forensics, attack methodologies, attack recognition, and similar topics. And oh, by the way, if you have any interest at all in certification, Intrusion Signatures and Analysis is the study guide for one of the hottest new certs there is: SANS GIAC Intrusion Detection In Depth.You want experience? The real-world signatures in this book, along with the analysis, make this a wonderful reference book. There is, of course, no substitute for experience. However, this book provides an excellent baseline of experience for any Intrusion Analyst! From that baseline one should be able to better analyze future attacks; there is, after all, only so much an attacker can do.
This book was made possible by contributors to GIAC (Global Incident Analysis Center); professionals out "in the trenches" dealing with attacks of all shape and size on a daily basis. These traces were not generated in a lab; they're the same traces you will see on your network if you're looking for them.
I've already used this book as a reference guide and it sits on my shelf next to "TCP/IP Illustrated V1" by Dr. Richard Stevens and "Intrusion Detection: An Analysts Handbook V2" by Stephen Northcutt and Judy Novak- I use all on a regular basis.
Whether you are just starting out in the IDS realm or whether you're an established Analyst sitting on an enterprise of sensors this book is for you.

Included in these detects are some of the more unique pieces of analysis that have been performed at GIAC, with detailed write-ups of the analysis process and the logic applied in defining the conditions in which the events occured.
Once again, this is easy and interesting reading which will appeal to intrusion analyists of all levels. Further, this book gives neophytes a real sense of what can be monitered and how important intrusion detection is in security layering.
