Nmap Network Scanning is the official guide to the Nmap Security Scanner, a free and open source utility used by millions of people for network discovery, administration, and security auditing. From explaining port scanning basics for novices to detailing low-level packet crafting methods used by advanced hackers, this book suits all levels of security and networking professionals. A 42-page reference guide documents every Nmap feature and option, while the rest of the book demonstrates how to apply those features to quickly solve real-world tasks. Examples and diagrams show actual communication on the wire.
Topics include subverting firewalls and intrusion detection systems, optimizing Nmap performance, and automating common networking tasks with the Nmap Scripting Engine. Hints and instructions are provided for common uses such as taking network inventory, penetration testing, detecting rogue wireless access points, and quashing network worm outbreaks. Nmap runs on Windows, Linux, and Mac OS X.
Nmap's original author, Gordon "Fyodor" Lyon, wrote this book to share everything he has learned about network scanning during more than 11 years of Nmap development. Visit http://nmap.org/book for more information and sample chapters.
Earlier this year Fyodor sent me a pre-publication review copy of his new self-published book, Nmap Network Scanning (NNS). I had heard of Fyodor's book when I wrote my 3 star review of Nmap in the Enterprise in June, but I wasn't consciously considering what could be in Fyodor's version compared to the Syngress title. Although the copy I read was labelled "Pre-Release Beta Version," I was very impressed by this book. Now that I have the final copy (available from Amazon) in my hands, I am really pleased with the product. In short, if you are looking for *the* book on Nmap, the search is over: NNS is a winner.
I've reviewed dedicated "tool" books before, including titles about Snort, Nessus, and Nagios. NNS dives into the internals of Nmap unlike any other title I've read. Without Nmap author Fyodor as the author, I think any competitor would need to have thoroughly read the source code of the application to have a chance at duplicating the level of detail Fyodor includes in NNS.
Instead of just describing how to use Nmap, Fyodor explains how Nmap works. Going even further, he describes the algorithms used to implement various tests, and why he chose those approaches. The "Idle Scan Implementation Algorithsm" section in Ch 5 is a great example of this sort of material. I will probably just refer students of my TCP/IP Weapons School class to this part of NNS when we discuss the technique!
One of the best parts of NNS, mentioned but explained in no other text, is the Nmap Scripting Engine (NSE). Ch 9 is all about NSE, with a brief intro to Lua and excellent documentation of using and building upon NSE. Beyond this groundbreaking material readers will find many examples of Nmap case studies from users. This and other sections help make NNS a practical book, showing how people use Nmap in their environments for a variety of purposes.
