The EC-Council|Press Ethical Hacking and Countermeasures series is comprised of four books covering a broad base of topics in offensive network security, ethical hacking, and network defense and countermeasures. The content of this series is designed to immerse the reader into an interactive environment where they will be shown how to scan, test, hack, and secure information systems. A wide variety of tools, viruses, and malware is presented in these books, providing a complete understanding of the tactics and tools used by hackers. The full series of books helps prepare readers to take and succeed on the C|EH certification exam from EC-Council.
The whole series is the curriculum for the Certified Ethical Hacker (CEH) curriculum. It does a great job preparing you for this exam. I was surprised how many of the tools in the curriculum are out of date or less than optimal compared to some better COTS tools out there. Granted, F/OSS should be covered extensively, but not to the exclusion of good COTS solutions.
