How to Use This Chapter

This chapter focuses on the key security considerations for ASP.NET applications. To get the most out of this chapter:

• Read Chapter 16, "Securing Your Web Server." This shows you how to secure the Windows 2000 operating system and the Microsoft .NET Framework. A secure underlying platform is a prerequisite for securing an ASP.NET Web application or Web service.

• Use the snapshot . Table 19.4, which is at the end of this chapter, gives a snapshot of a secure ASP.NET application with secure configuration settings in Machine.config and Web.config. Use this table when configuring your server and application settings.

• Use the checklist . The "Checklist: Securing Your ASP.NET Application" in the "Checklist" section of this guide provides a printable job aid for quick reference. Use the task-based checklist to quickly evaluate the scope of the required steps and to help you work through individual steps.

For related guidance, read Chapter 20, "Hosting Multiple ASP.NET Applications," which shows you how to isolate multiple Web applications running on the same server from critical system resources and from one another. For more information about configuring code access security (CAS) policy for partial-trust Web applications and Web services, see Chapter 9, "Using Code Access Security with ASP.NET."
