This book is an easy-to-read guide to using IPCop in a variety of
different roles within the network. The book is written in a very
friendly style that makes this complex topic easy and a joy to read. It
first covers basic IPCop concepts, then moves to introduce basic IPCop
configurations, before covering advanced uses of IPCop. This book is
for both experienced and new IPCop users.

What you will learn from this book

Chapter 1 briefly introduces some firewall and networking concepts. The
chapter introduces the roles of several common networking devices and
explains how firewalls fit into this.

2 introduces the IPCop package itself, discussing how IPCop’s
red/orange/blue/green interfaces fit into a network topology. It then
covers the configuration of IPCop in other common roles, such as those
of a web proxy, DHCP, DNS, time, and VPN server.

Chapter 3
covers three sample scenarios where we learn how to deploy IPCop, how
IPCop interfaces connect to each other and to the network as a whole.

4 covers installing IPCop. It outlines the system configuration
required to run IPCop, and explains the configuration required to get
IPCop up and running.

In Chapter 5, we will learn how to employ
the various tools IPCop provides us with to administrate, operate,
troubleshoot, and monitor our IPCop firewall

Chapter 6 starts
off with explaining the need for an IDS in our system and then goes on
to explain how to use the SNORT IDS with IPCop.

Chapter 7
introduces the VPN concept and explains how to set up an IPSec VPN
configuration for a system. Special focus is laid on configuring the
blue zone — a secured wireless network augmenting the security of a
wireless segment, even one already using WEP or WPA.

Chapter 8
demonstrates how to manage bandwidth using IPCop making use of traffic
shaping techniques and cache management. The chapter also covers the
configuration of the Squid web proxy and caching system.

9 focuses on the vast range of add-ons available to configure IPCop to
suit our needs. We see how to install add-ons and then learn more about
common add-ons like SquidGuard, Enhanced Filtering, Blue Access,
LogSend, and CopFilter.  

Chapter 10 covers IPCop security risks, patch management and some security and auditing tools and tests.

Chapter 11 outlines the support IPCop users have in the form of mailing lists and IRC.
