Who should read this guide What is covered in this guide P R E F A C E About this Guide This guide is intended for a Sidewinder G2 administrator. You should read this guide if you are responsible for configuring and managing a Sidewinder G2 Security Appliance. This guide assumes you have: A working knowledge of UNIX and Windows operating systems. A basic understanding of system administration. A working knowledge of the Internet and its associated terms and applications. An understanding of networks and network terminology, including TCP/IP protocols. This guide provides complete administration information on all Sidewinder G2 security appliance functions and features. If you are already responsible for the network to which the Sidewinder G2 will be connected, you will find that you perform the same basic administrative tasks on the Sidewinder G2. However, some of these tasks will differ from standard UNIX systems because of the extra security mechanisms that are included with Sidewinder G2. Note: Because it is much easier to administer the Sidewinder G2 using the Admin Console rather than by entering commands, this document focuses on using the Admin Console whenever possible. Each chapter in this guide describes the use and general configuration of one or more related Sidewinder G2 features. Each chapter also includes background information to describe how the underlying technology relates to a Sidewinder G2 configuration. Table 1 provides a description for each chapter included in this guide. P Preface: About this Guide xix
