uch has changed since the first edition of Firewalls and Internet Security was published in 1994. For one thing, the Web was still a rather obscure concept for most people at that time, so this edition is nearly a complete rewrite.
This book will teach you how to plan and execute a security strategy that allows easy access to Internet services while defeating even the wiliest of hackers. Firewalls and Internet Security was written by well-known senior researchers at AT&T Bell Labs, Lumeta, and Johns Hopkins University. You will benefit from their actual, real-world experience maintaining, improving, and redesigning AT&T’s Internet gateway.
