In the five years since the first edition of this classic book, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. Like the highly respected, bestselling first edition, Building Internet Firewalls, 2nd Edition, is a practical and detailed step-by-step guide to designing and installing firewalls and configuring Internet services to work with a firewall. Much expanded to include Linux and Windows coverage, the second edition describes a variety of firewall technologies and architectures. It also contains a new set of chapters describing the issues involved in a variety of Internet services and protocols through a firewall. In addition to the standard email, News, FTP, DNS, and Telnet services, the book now covers web services and scripting languages, Windows NT services, authentication and auditing services, intermediary protocols, and database protocols. The book also has a complete list of resources, including the location of many publicly available firewall construction tools.
