"My students and I are big fans of this book. I have been using it regularly, since its publication, in the course "Network Security" that I teach in the Master of Science Program "Engineering and Computer Science" at the University of Verona, Italy. The course is structured in a number of theory lectures, covering the main aspects of network security, accompanied by a lab in which I have adopted [this] book. [It] delivers successfully and elegantly what it promises: it complements in an interesting and unique way the theory lectures. It allows students to carry out exercises and experiments on the topics that have been discussed in the lectures and, thanks to the accompanying software, they can choose to do this in the university lab or at home (or both). The assignment project proposed at the end of the book challenges the students in a very proficient way and, indeed, the ratings of the course by students have risen considerably since I adopted the book."   (Luca Viganò, Università di Verona, Italy)

"[F]or those looking for an intense but brief and concentrated introduction to some of the fundamentals of information security, to supplement other more comprehensivereferences, [this] is an excellent book." (Ben Rothke)
