This book walks readers through the process of setting up a secure E-commerce Web site. It includes implementation examples for Unix (Solaris and Linux), Windows NT 4.0, and Windows 2000. The authors pay particular attention to the security issues involved. They also highlight the plethora of encryption algorithms that are instrumental in securing data. Together, the authors and the reader develop a site from concept to implementation. The material makes use of numerous coding examples to illustrate how to use the most current technologies - from Microsoft, Sun, and others - to support secure transactions.
