A truly wonderful book, well deserving of its legandary status. Seems to cover Unix security from just about every angle possible, and even as a Sys Admin of 5 years' experience, I felt it had a lot to teach me. Not only is it informative, but it's also quite witty as well!

I would love to see these guys write an 'advanced' companion volume, with examples of the weak coding that resulted in past sendmail/fingerd exploits, etc.
