Hands-on Ethical Hacking and Network Defense
This is the textbook for a course I am doing at the moment. To be honest the book is kind of old and nothing special, but I read it so it gets at least a brief mention here. Overall the book is too dated to be particularly useful, and I find it hard to believe that something better hasn't been published in the intervening 11 years. That said, if I ever need to enumerate NetWare servers (remember those?) I'll know where to look for information!
