When consider a title, the audienced and projected population should be considered. This book fails both.I read a lot of computer books, since I work on networks and I wouldn't want to do anything else for a living. I hope the authors have something other to do than writing, since they do it so very poorly. The book is badly titled and terribly written. After an hour's struggle I set it aside. It rambles and presents topics such that retention is all but impossible. Simply put, Hacking Exposed has nothing to do with hacking, cracking and everything to do with the boring diatribes of those big on theorectical security and lean on practice. Deep discounts are definately in order.
