Preface This IBM Redbook provides IT Architects, IT Specialists, application designers, application developers, application assemblers, application deployers and consultants with information to design, develop and deploy secure e-business applications using WebSphere Application Server V5. Part 1, “WebSphere security” on page 19 provides a detailed overview of WebSphere Application Server V5 Security. It starts with J2EE security and goes into details about the modules and components of a J2EE enterprise application; it also discusses programmatic security techniques. The last chapter of this part shows all the security related administrative items in WebSphere Application Server V5. Part 2, “End-to-end security” on page 347 offers details about end-to-end security solutions where WebSphere Application Server V5 is part of an enterprise solution. You will find an introduction to Patterns for e-business, in which security is in focus. A very important chapter in this part will discuss the integration between WebSphere Application Server V5 and Tivoli Access Manager. The “Appendixes” on page 443 provide additional information related to chapters from Part 1 and Part 2 and also describe the sample application available with the book. © Copyright IBM Corp. 2002 xi
