Most of the Dummies series books are appetite wetters at best and that's where they end.

They touch on the advanced things but don't explain enough for you to really fully realize the potential of anything. It's sort of like going into a suntan studio with a 3/4 raincoat on. You might get something out of being there but not enough for it to really be useful.

This book is no exception.

While it does touch on things such as ARP poisoning and Net Stumbler as well as some other useful starting points, it leaves a lot to be desired when it comes to expanding enough to make things worthwhile. It's a good introduction book but if you're planning on doing some real penetrations or penetration testing there are better books suited for this.

I would call this one a pre-reference reference book. At best.
