Chapter 16: Security 397Figure 16-4 Login page appears automaticallyon a production server. The full path for an IIS server on your computer would be OS(C:)> inetpub > wwwroot.Once everything is in place, open your browser and navigate to an ASPX file. As soonas you do, you will be redirected to the Login file as shown in Figure 16-4. If you put inan incorrect username or password, you will see the message that your attempt failed.Ask the ExpertQ: Isn’t it risky to put the login name and password in the C# code? Wouldn’t it befairly easy for a hacker to get those?A: You bet! The C# portion of the login example is to illustrate how theFormsAuthentication class can be used to send the requested URL to theuser after she has successfully logged in. Besides being a fairly risky way ofprotecting a username and password, it’s awkward to store username and passwordinformation in a coded format. Imagine a site that has thousands of users. So keepin mind that the login example is to show how the web.config file can redirecta request to a login page and how the FormsAuthentication class sends thelogged-in user to the requested URL.
398ASP.NET 3.5: A Beginner’s GuideOnce the username and password have been verified, the page you originally requestedappears. If you attempt to open a non-ASPX file such as an HTML file, your request willnot be filtered, and the target URL opens immediately.Membership SecurityFor strong security, ASP.NET 3.5 provides a system for storing usernames and encryptedpasswords in a special database. You can set up this security in different ways using VisualStudio 2008. Many of the most important elements are set up automatically, includingthe database with the default name of ASPNETDB.MDF. To see how everything works,a simple example goes through an extensive number of steps to add users and roles thatcan be created.Select ASP.NET ConfigurationFigure 16-5 Opening the Web Site Administration Tool
