Product Description:
Nmap, or Network Mapper, is a free, open source tool that is available under the GNU General Public License as published by the Free Software Foundation. It is most often used by network administrators and IT security professionals to scan corporate networks, looking for live hosts, specific services, or specific operating systems. Part of the beauty of Nmap is its ability to create IP packets from scratch and send them out utilizing unique methodologies to perform the above-mentioned types of scans and more. This book provides comprehensive coverage of all Nmap features, including detailed, real-world case studies.
. Understand Network Scanning
Master networking and protocol fundamentals, network scanning techniques, common network scanning tools, along with network scanning and policies.
. Get Inside Nmap

I've been a system administrator for several years. I've never used Nmap before because I thought it was just a hacking tool. Two months ago one of our security consultants had this book with him and I took a look at it. I had no idea that Nmap could be used to do so many everyday tasks. I ordered my copy that day and I have been using Nmap ever since.
Chapter 1 is a basic overview of basic network protocols, OSI model, and network scanning techniques. A new user (and especially someone new to security) will find this information very useful and informative. More experienced users can probably skip this chapter. One good piece of advice in this chapter is to make sure you have permission to run Nmap. As a system administrator of an entire domain I have permission to use tools like Nmap, but I did receive a call from the security folks because they don't usually see Nmap traffic in my segment! (Chapter 8 shows how they discovered it)
Chapter 2 has some good information on using Nmap to perform network inventory, assessment management, and compliance testing. I created a simple script that runs every morning and sends me a report of the active hosts, what operating system they are running, what ports are open, and what services are installed. This is great! I discovered a system already that someone had installed an application on overnight that is not allowed per our company policy. I was able to quickly locate the system and have the administrator remove the application. I used the information in Chapter 4 to put together my scripts. It has a lot of good examples. I really like the additional features you get with Zenmap such as the Command Wizard and the ability to create profiles. I created profiles for the commands I commonly run for each of my zones.
Chapter 6 - WOW - this chapter gets into the weeds of Nmap fingerprints. I especially liked how this chapter also pointed out how to use Nmap to justify your IT budget. I will be putting that advice to good use soon to justify OS and application upgrades!
NDiff has already come in very handy and I am hoping to port some of my scripts to Bilbo. I am going to start using some of the monitoring techniques in Chapter 8 to monitor my domain to make sure no one else is scanning. I also plan to move on to some of the advanced scanning techniques covered to learn about evasion, spoofing, and perimeter device testing, but I'm not there yet. I highly recommend this book for other folks like me who manage systems and networks, it has made my job a lot easier!

Wow. What a light weight book! I expect (and usually receive) MUCH better from Syngress. This book would make a good "Dummies" book, but it is way too lightweight for a security professional's use.
Editorially, the book is well written, and Syngress did its usual good job of finding all the typos. (I think I only saw one really glaring typo in the book.) Where Syngress fell down was on content review, and having someone review the book for an appropriate depth of content. Their marketing folks also greatly overhyped the content on the book's covers, giving the impression of in-depth content on topics that have only minimal coverage.
I purchased the book because it was advertised as having information on "Automate Tasks with the Nmap Scripting Engine." Yeah, 3 pages. Reading the description of the book, I would have expected great detail on the NSE, including how to write NSE scripts. Not a word of advise on how to do so. Not even an illustration showing a sample script.
The cover of the book also advertises "Analyze Real-World Scans and Examples." That lead me to expect to pick up new tips and tricks on using nmap's advanced scanning capabilities. I had hoped to find some examples of creating and interpreting advanced scans. Not a word on how to create and interpret anything more than trivial to basic scans.
I was also hoping to have see some detailed and in-depth information in the book about firewall testing and IDS evasion. Again, little to no content here.
If you have ever actually read the nmap man page, don't waste your money on this book. You would be better off reading some of the papers on Fyodor's (namp's creator) web site (http://nmap.org/docs.html) and save yourself $50. Or, save your money and buy Fyodor's book when it comes out 'any day now.'
I really have to wonder if the authors have ever even seen Fyodor talk on nmap at any of the security conferences. If they had, I would have thought that the book would have had a lot more depth than it did. Even his most basic talks have FAR more depth than this book.
I am really really disappointed in this book. Syngress should have had it reviewed by someone who is an advanced user of nmap. I cannot believe how little information there is in this book for anyone beyond a very first time user.
I notice that one of the authors is working on her PhD. I hope she puts a lot more detail and depth into her dissertation than she did this book. Otherwise, I can guarantee her it would never make it out of committee.

For a book that's roughly 200 pages long (and it's a smaller book in terms of overall dimensions--near "pamphlet" size) I was somewhat disappointed with the book. Many IT related books are far less expensive! The contents of the book matched much of the information found on Nmap's site (insecure.org). The number of URL links in this book (pointing to this site) made me feel like I should have saved my 40 bucks and gone straight to the website. If you're looking for comprehensive information on Nmap just buy Fyodor's/Insecure.org's book (which should be out in the subsequent month). Of course, if you prefer to have your bank account 'hacked' (losing 40 some dollars) feel free to buy this book instead.

Initially I hoped Nmap in the Enterprise (NITE) would live up to its title. I was excited to see "Automate Tasks with the Nmap Scripting Engine (NSE)" on the cover, in addition to the "Enterprise" focus. It turns out that beyond a few command line options of which I was not previously aware, and some good info on interpreting OS fingerprinting output in Ch 6, I didn't learn much by reading NITE. If you are new to Nmap or network scanning you will probably like NITE, but if you want a real enterprise focus or information on NSE you will be disappointed.
If you're going to make "Enterprise" part of the title for NITE, I would expect more attention paid to one of the biggest problems in enterprise scanning: data management. You can scan all you want, but the real problem is doing something intelligent with the output. With about 21 pages of text, Ch 7 (Tooling Around With Nmap) is the closest NITE comes to saying something about managing Nmap output beyond the single, smallish scan scenario. Unfortunately, the chapter is not up to the task.
Some might consider it unfair to criticize the book if there really is no enterprise-quality Nmap support application available. If that is the case, I have two replies. First, change the focus. Second, implement that application, and include it in the book. If you think the second is too much work, consider my reviews of the Hacking Exposed titles on Wireless, VoIP, or Cisco. All three author teams wrote specific tools to address shortcomings in each of their subject areas, and then included them in their three books. Not all authors can do this, but that level of effort really contributes to an outstanding book.
Turning to NSE, I hoped to learn about how to use Lua scripting with Nmap. The section on NSE is less than three full pages (pp 116-118) and basically concludes with a reference to the Nmap home page for more information. In the one place where the newest book on Nmap could have differentiated itself from its predecessors (many other Syngress books, Osborne's Anti-Hacker Toolkit or Hacking Exposed, and so on), NITE avoids the issue.
Aside from these issues, NITE is a good book for those with basic or perhaps intermediate experience with Nmap. Most of the items I found useful could have been gleaned from the Nmap man page or changelog, but I'll mention a few here. P 96 shows using the --reason switch to give more detail on responses from targets. PP 97-99 show using the -sL switch for list scans and -PN as the replacement for -P0. Note that Table 4.2 says -sN replaces -P0; it should say -PN replaces -P0 due to confusion with -PO (used for Internet Protocol enumeration). I liked the --osscan-limit switch on p 111 to only perform OS identification against targets offering at least one open and one closed port. P 127 reminded me of runtime interaction commands, like v/V for verbosity, d/D for debugging, and p/P for packet tracing. P 129 demonstrated the value of using --log-errors.
Ch 6 (Nmap OS Fingerprinting) was my favorite chapter. I liked the explanation of the components of an OS fingerprint. I hadn't seen this so thoroughly explained elsewhere, although it might exist. Overall, I should mention that the book was much better written than the average Syngress title. I credit the two (and only) authors for this level of quality.
If you have no other references for Nmap, and you use the tool in limited engagements, you should buy this book. If you're looking for help with real enterprise use or advanced Nmap usage, keep looking. Perhaps a second edition will address these issues?

I've been using Nmap for a few years now as a basic scanner, not needing more that the little that I have needed it. This book give a great overview to the basics of nmap and good ways to log your scans. it's very current, they use nmap 4.50 in the book and 4.60 just came out so it's very current. For any network administrators out there that haven't used nmap or were scared of the command line, get this book. nmap is the best, you'll learn a great deal about using it in your network to map your network out. The authors show you how to log, do some assessment tests, scan, etc.
it's funny that ethereal/wireshark, snort...etc all have many books written about them, but there's only 2 that i know of for nmap, this one, Professor Messer has a whole site dedicated to nmap and he has written an ebook (also own it, great! and he has webinars). I know Fyodor is compiling a book but who knows when that'll be out.
Do yourself a favor if you administer any network, get this book because nmap will be your new best friend!!!
Great!
