hacking linux exposed 3rd edition is a complete rewrite and (in my opinion) loses the power of the previous editions.



the first two editions have numerous examples of exploits followed by appropriate strategies for defending against them. the current edition is jargon and alphabet soup found within the field of security. about the only redeeming feature of the latest edition is a concise summary of security software for linux found in the appendix.



i teach linux security (usually in the spring) and i know how difficult it is keep current with examples of exploits. what i demonstrate one year is unavailable the next! however, the red books really attempted to demonstrate the various vulnerabilities the blue book is generality and vocabulary.
