This book is essential reading for anyone wanting to protect Internet-connected computers from unauthorized access. Coverage includes TCP/IP, setting up firewalls, testing and maintaining firewalls, and much more. All of the major important firewall products are covered including Microsoft Internet Security and Acceleration Server (ISA), ISS BlackICE, Symantec Firewall, Check Point NG, and PIX Firewall. Firewall configuration strategies and techniques are covered in depth.
The book answers questions about firewalls, from How do I make Web/HTTP work through my firewall? To What is a DMZ, and why do I want one? And What are some common attacks, and how can I protect my system against them?
The Internet's explosive growth over the last decade has forced IT professionals to work even harder to secure the private networks connected to itfrom erecting firewalls that keep out malicious intruders to building virtual private networks (VPNs) that permit protected, fully encrypted communications over the Internet's vulnerable public infrastructure.
