Attacks on government Web sites, break-ins at Internet service providers, electronic credit card fraud, invasion of personal privacy by merchants as well as hackers--is this what the World Wide Web is really all about? Web Security & Commerce cuts through the hype and the front page stories. It tells you what the real risks are and explains how you can minimize them. Whether you're a casual (but concerned) Web surfer or a system administrator responsible for the security of a critical Web server, this book will tell you what you need to know. Entertaining as well as illuminating, it looks behind the headlines at the technologies, risks, and benefits of the Web. Whatever browser or server you are using, you and your system will benefit from this book. Topics include:
Digital certificates--what they are, how they assure identity in a networked environment, how certification authorities and server certificates work, and what code signing all about.
Cryptography--an overview of how encryption works on the Internet and how different algorithms and programs are being used today.
Web server security--detailed technical information about SSL (Secure Socket Layer), TLS (Transport Layer Security), host security, server access methods, and secure CGI/API programming.
Commerce and society--how digital payments work, what blocking software and censorship technology (e.g., PICS and RSACi) is about, and what civil and criminal issues you need to understand.

A. Lessons from Vineyard.NET
Planning and Preparation
- Lesson: Whenever you are pulling wires, pull more than you need.
- Lesson: Pull all your wires in a star configuration, from a central point out to each room, rather than daisy-chained from room to room. Wire both your computers and your telephone networks as stars. It makes it much easier to expand or rewire in the future.
- Lesson: Use centrally located punch-down blocks or 10Base-T wiring blocks for both your computer networks and your telephone networks.
- Lesson: Don’t go overboard.
- Lesson: Plan your computer room carefully: you will have to live with its location for a long time.
- IP Connectivity
- Working with the Phone Company
- Incorporating Vineyard.NET
- Initial Expansion
- Accounting Software
- Publicity and Privacy
- Lesson: Don’t run programs with a history of security problems (e.g., sendmail).
- Lesson: Make frequent backups.
- Lesson: Limit logins to your servers.
- Lesson: Beware of TCP/IP spoofing.
- Lesson: Defeat packet sniffing.
- Lesson: Restrict logins.
- Lesson: Tighten up your system beyond manufacturer recommendations.
