| summary | Great pentesting book |
Assessing Network Security starts with a nice overview of key principles of security (definitely not news for industry practitioners, but nice anyway), and then goes on to defines vulnerability assessment, penetration testing and security audit. A critically important section on reporting the findings is also nicely written, and shows that the authors are knowledgeable, and interested in showing a complete security process rather than just the looking-for-leaks part.
The authors then go into developing and maintaining pentesting skills, including advice on choosing training and resources (nice for those starting in the field). The actual pentesting process is split into non-intrusive (combining the usual "intelligence gathering" with port scans, sweeps and various host queries) and intrusive tests (such as running a vulnerability scanner, brute-forcing passwords, DoS testing and others). Some entries seem to belong in both categories (such as sniffing) but are placed into the intrusive section, for whatever reason. Up-to-date content (wireless, Bluetooth and web assessment, for instance) is well represented.
The authors also include a fairly insightful social engineering testing section (touching on dumpster diving and other non-network assessment methods). My favorite chapter was the one presenting various case studies - examples of specific threats/tests against Web, email, VPN and domain controller systems.
Among other features that I liked in Assessing Network Security were 'notes from the field' sidebars with fun stories related by authors, and FAQs at the end of each section. On the down side, the book is somewhat Windows-focused (although it is amazingly vendor-neutral in most respects, considering the source). The book is also somewhat dry, although the sidebars provide some needed relief when the text gets too process-oriented at times.
Assessing Network Security is largely about methodology, but I'd have preferred to see a bit more technical content, since it is a 600-page volume. I think the checklists present in the Appendix are a great step in that direction.
Overall, I enjoyed the book and think it is both a great guide and a reference for most security professionals, especially for those starting to be involved with penetration testing.

The utility of the book comes from not just spreading the word about security, but having to do so in forums and formats that require it to be relevant, useable and correct.
As a security consultant and trainer myself I can attest to the gap between theory and practice and the need to put security issues in to terms that are able to be applied in the real world.
Comments above that assume that just because someone works for Microsoft, they don't know how things work in reality are generalisations made out of ignorance or jealousy. This book is a good example that the truth about Microsoft employees, like security, is often misunderstood.

I'm not talking about just potential root exploits and the like, but also about things like file permissions, which I find are hard to get exactly right on Unix (read: Linux with no special ACL stuff installed), where the file system does not support inheritance of security attributes.
Many Linux distros come with a script that's run nightly to report potential vulnerabilities, changed files etc. There are also tools like Snort and Tripwire. I also use Munin and check it daily for signs of DOS attacks and other suspicious activity (eg., a sudden increase in the number of listening ports).
