LOL. At the ACCU conference, I read all of the security books. They’re all crap.
One particularly memorable one has “world’s best security reference” as part of the cover text. And yet, with a whole chapter on Samba, it “forgets” to mention the hashing scheme used by Samba - MD4, otherwise known as “crackable by any moron in approximately 3 hours, and soon to be crackable instantaneously, we’re just waiting for the freely available kit to be completed”.
This is quite apart from failing to explain the key elements of the SMB password system, and the main gotchas, DESPITE the fact that I know they are written in to the manpages!
So much crap out there in books. Sigh.
