What you are holding in your hands now is a book about Check Point FireWall-1 NG. It covers the essentials of the product. Each chapter discusses a major feature of the product or a specific topic that will help you plan for or maintain your FireWall-1 NG installation. You get step-by-step configuration instructions for many features in FireWall-1 complete with screenshots and several sample configurations you can try. The book also includes lots of information from my FireWall-1 Frequently Asked Questions (FAQs) on http://www.phoneboy.com.
Not every feature of FireWall-1 is covered in this text. The "essential" features I have chosen to cover are based on my experience as someone who has supported this product since 1996. Other peripheral topics, like encryption and network security, are covered briefly as they relate to FireWall-1 but are not covered in great detail. I feel that other authors do a better job of covering these topics?some examples are provided in Appendix H.
A summary of the chapters in this book follows. Note that where sample configurations are said to exist in a chapter, it means there are step-by-step examples you can follow to set up your own equipment, provided you have it.
