Organization and Elements of This Book

When designing a secure network infrastructure, the workflow moves from the perimeter of the network to the inside of the network. After the perimeter is properly secured, the security architect can turn his or her attention to securing devices on the inside of the network perimeter where the endpoints reside. This structured approach is mimicked in the basic organization of this book.

The chapters of this book are organized into four major parts, with each part encapsulating a major idea in the field of network security:

    Part I: Network Security Architecture

    Part II: Perimeter Security
