Summary: Mixed Bag
Review: Up through Chapter 7, this book presents a fairly good overview of information security in general, network security basics, cryptography, and a good measure of "security philosophy" as well. It reads pretty well and there are relatively few inconsistencies, until...From Chapter 8 onwards, there are lots of mistakes (my personal favorite is a botched explanation of TCP proxies on page 248) and many cases of examples not matching the explanatory text. And when it comes to enabling TACACS+ on routers, some sections of this book directly contradict Cisco's "IOS 12 Network Security" book. All in all, a decent reference for Cisco routers & firewalls, but you might want to supplement it with something more substantial. The O'Reilly books and Cheswick/Bellovin come to mind...
