Title: Exactly on the mark!
Review: This book is exactly "on" regarding the SECUR exam. It is definitely worth adding to the library. It is clear, concise and right to the point. Several concepts such as character and interface mode and the Intrusion Detection System (IDS) on the router, which are critical to understand for certification, were picture perfect along with the other components of this book. I don't believe I have seen a more direct and to the point explanation on IPSec than the one contained inside the pages of this book. Even if you are not pursuing certification, this book will help clear up misconceptions regarding security and the IOS router with the firewall feature set.It is a "keeper".
