33. Security is one of the most important component of any application. Security

34. Using Authentication in ASP.NET • Authentication is a process of determining how you will verify a client’s identity when the client requests a page. • Authorization is the process of determining which clients have access to the resources within the web application or current directory. T.AhlamAlgharasi

35. Using Authentication in ASP.NET Requesting a web page that requires authentication T.AhlamAlgharasi

36. Using Authentication in ASP.NET • Authentication is implemented through one of four possible authentication systems: • Windows authentication • Forms authentication • Passport authentication • No authentication T.AhlamAlgharasi

37. Using Authentication in ASP.NET • Windows Authentication • The Windows authentication allows us to use the windows user accounts. Windows authentication in ASP.NET actually relies on IIS to do the authentication. IIS can be configured so that only users on a Windows domain can log in. If a user attempts to access a page and is not authenticated, they'll be shown a dialog box asking them to enter their username and password. T.AhlamAlgharasi

38. Using Authentication in ASP.NET • Passport Authentication • Passport Authentication provider uses Microsoft's Passport service to authenticate users. • You need to purchase this service in order to use it. T.AhlamAlgharasi

39. Using Authentication in ASP.NET • Form Authentication • Forms Authentication uses HTML forms to collect the user information and than it takes required actions on those HTML collected values. • The advantage of using this type of authentication • It allows you to decide how to store user information. (storing username and password in the Web.Config file, an XML file, or a database table.) T.AhlamAlgharasi

40. Using Authentication in ASP.NET • Enabling Form Authentication • To enable basic Forms authentication for an application, the follow three steps are to be followed: • Set the authentication mode for the application by modifying the authentication ­section in the application root Web.Config file. • Deny access to anonymous users in one or more directories in the application by modifying the authorization section in the Web.Config files in the appropriate directories. • Create a login page containing a form that enables users to enter their usernames and passwords. T.AhlamAlgharasi

41. Using Authentication in ASP.NET • To perform Form Authentication • Secure pages in a separate subfolder • Create a web.config file inside the subfolder • Create web configuration file in the folder you want to secure it • Create web configuration file in the root directory. T.AhlamAlgharasi

42. Using Authentication in ASP.NET • Web.Config File • Web.config file (Web configuration file) it keeps the configurations required for the web application. • There are number of important settings that can be stored in the configuration file. • Database connections • Session States • Error Handling • Security T.AhlamAlgharasi

43. Using Authentication in ASP.NET • Forms Authentication Configuration • Configure Forms Authentication in Web.Config. <authentication mode="Forms">        <forms loginUrl="~/login.aspx“ defaultUrl="~/adminpages/welcome.aspx” /> </authentication> T.AhlamAlgharasi

44. Using Authentication in ASP.NET • Forms Authentication Configuration T.AhlamAlgharasi

45. Using Authentication in ASP.NET • Authorization Configuration • Configure Authorization in Web.Config (Subfolder). • Use an <authorization> element to ensure that only authenticated users can access secure pages. <system.web> <authorization> <deny users="?"/> </authorization> </system.web> T.AhlamAlgharasi

46. Using Authentication in ASP.NET • Permissible elements for authorization are • Allow • Deny. • Each allow or deny element must contain a users attribute. T.AhlamAlgharasi

47. Using Authentication in ASP.NET • Creating the Login Page • The ASP.NET login controls provide a robust login solution for ASP.NET Web applications without requiring programming. • By default, login controls integrate with ASP.NET forms authentication to help automate user authentication for a Web site. T.AhlamAlgharasi

48. Using Authentication in ASP.NET • Login Page Control properties T.AhlamAlgharasi

49. Using Authentication in ASP.NET • Login Page Control Styles T.AhlamAlgharasi

50. Using Authentication in ASP.NET • Login code T.AhlamAlgharasi
