Now, I've read some pretty bad books on penetration testing and nobody seemed to get this fun subject right! Good news - this time somebody did! This great tome ("Assessing Network Security") comes to us direct from the bunkers of Redmond. Written by three Microsoft security researchers, the book provides a great overview as well as in-depth coverage of assessing security via pen testing, scanning, IT audit and other means.
The books starts from 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 about the subject. The book then goes into developing and maintaining the pentesting skills, and descends into choosing the 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. All the host latest content (wireless, Bluetooth and web assessments) is well represented in the book. A fairly insightful social engineering testing section (that touched on dumpster diving and other non-network assessment methods) is also present. My favorite chapter was the one on 'case studies' - examples of specific threats/tests against web, email, VPN and domain controller systems.
Among other features that I liked 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 sidebars provide the needed relief when the text gets too process-oriented at times.
The book 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 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.
