This book was written to accomplish one goal: to teach network administrators what they need to know to understand the Internet security threat, the technologies used to prevent it, and the products that exist to help them. It's the book I wish I'd had when I couldn't find a common language between various vendors that I could use to compare firewall literature and books heavy on theory to the marketing blurbs I read on websites, or when I needed help matching a specific customer's requirements to a specific firewall product.
