Take a Practice Test
The practice tests on this book s companion CD offer many options. For example, you can test yourself on just the content covered in this chapter, or you can test yourself on all the 70-536 certification exam content. You can set up the test so that it closely simulates the experience of taking a certification exam, or you can set it up in study mode so that you can look at the correct answers and explanations after you answer each question.

Application Security
Everyone has heard that you shouldn t log on to your computer as an Administrator. The reason isn t because you don t trust yourself not to delete your hard drive; it s because you don t trust the applications you run. When you run an unmanaged application in Microsoft Windows Server 2003, Microsoft Windows XP, and earlier versions of Windows, that code gets all the privileges your user account has. If you accidentally run a virus or a Trojan horse, the application can do anything your user account has permissions to do. So you are forced to log on with minimal privileges to restrict application permissions. Code access security (CAS), a concept that the .NET Framework introduced to Windows, enables you to control the permissions that individual applications have. If a friend sends you a new .NET Framework text editor, you can restrict it to opening a window and prompting you to open and save files and nothing else. The text edited wouldn t be able to send e-mails, upload files to a Web site, or create files, even if you are logged on as an Administrator. CAS enables users to restrict on a very granular level what managed code can do. As a developer, you must understand how to create applications that work even when some permissions are restricted. You can also use CAS to improve your application s security by restricting which callers can use your code and forcibly limiting your application to a restricted permission set.
