System.Web.Security Namespace

The System.Web.Security namespace contains classes that are used to implement ASP.NET security in Web server applications.

Remarks

The Membership class is used by ASP.NET applications to validate user credentials and manage user settings such as passwords and e-mail addresses. The Roles class enables you to manage authorization for your application based on groups of users assigned to roles in the Web application.

Both the Membership class and the Roles class work with providers, classes that access your application's data store to retrieve membership and role information. Membership and role information can be stored in a Microsoft SQL Server database using the SqlMembershipProvider and SqlRoleProvider classes; in an Active Directory using the ActiveDirectoryMembershipProvider and AuthorizationStoreRoleProvider classes, or in a custom data source using implementations of the MembershipProvider and RoleProvider classes.

You configure ASP.NET membership using the membership Element (ASP.NET Settings Schema). When an application using membership is accessed, ASP.NET creates an instance of the Membership class that you can use to query membership information. Provider-specific implementations of the MembershipUser class contain information about the user accessing the page. You can create custom implementations of the MembershipUser class for your application.

You configure ASP.NET roles using the roleManager Element (ASP.NET Settings Schema). ASP.NET creates an instance of the Roles class that contains information about the role membership of the current user.

ASP.NET provides server controls that interact with the Membership class and the Roles class. The Login, CreateUserWizard, and ChangePassword controls work with the Membership class to simplify creating an authenticated Web application, and the LoginView control uses role-specific templates to customize Web pages for specific groups of users.

Classes

TypeReason

Describes how information in a cookie is protected.

DefaultAuthenticationEventArgs

Provides data for the DefaultAuthentication_OnAuthenticate event. This class cannot be inherited.

DefaultAuthenticationEventHandler

Represents the method that handles the DefaultAuthentication_OnAuthenticate event of a DefaultAuthenticationModule.

DefaultAuthenticationModule

Ensures that an authentication object is present in the context. This class cannot be inherited.

FileAuthorizationModule

Verifies that the user has permission to access the file requested. This class cannot be inherited.

FormsAuthentication

FormsAuthenticationEventArgs

Provides data for the FormsAuthentication_OnAuthenticate event. This class cannot be inherited.

FormsAuthenticationEventHandler

Represents the method that handles the FormsAuthentication_OnAuthenticate event of a FormsAuthenticationModule.

FormsAuthenticationModule

Sets the identity of the user for an ASP.NET application when forms authentication is enabled. This class cannot be inherited.

FormsAuthenticationTicket

Provides access to properties and values of the ticket used with forms authentication to identify users. This class cannot be inherited.

FormsIdentity

Represents a user identity authenticated using forms authentication. This class cannot be inherited.

Membership

Validates user credentials and manages user settings. This class cannot be inherited.

MembershipCreateStatus

Describes the result of a Membership.CreateUser(String,String) operation.

MembershipCreateUserException

The exception that is thrown when a user is not successfully created by a membership provider.

MembershipPasswordException

The exception that is thrown when a password cannot be retrieved from the password store.

MembershipPasswordFormat

Describes the encryption format for storing passwords for membership users.

MembershipProvider

Defines the contract that ASP.NET implements to provide membership services using custom membership providers.

MembershipProviderCollection

A collection of objects that inherit the MembershipProvider abstract class.

MembershipUser

Exposes and updates membership user information in the membership data store.

MembershipUserCollection

A collection of MembershipUser objects.

MembershipValidatePasswordEventHandler

Represents the method that will handle the MembershipProvider.ValidatingPassword event of the MembershipProvider class.

PassportAuthenticationEventArgs

The event argument passed to the PassportAuthenticationModule.Authenticate event by a PassportAuthenticationModule. Since there is already an identity at this point, this is useful mainly for attaching a custom IPrincipal object to the context using the supplied identity. This class is deprecated.

PassportAuthenticationEventHandler

Represents the method that handles the PassportAuthentication_OnAuthenticate event of a PassportAuthenticationModule. This class is deprecated.

PassportAuthenticationModule

Provides a wrapper around Passport Authentication services. This class cannot be inherited. This class is deprecated.

PassportIdentity

Provides a class to be used by PassportAuthenticationModule. It provides a way for an application to access the PassportIdentity.Ticket(String) method. This class cannot be inherited. This class is deprecated.

RoleManagerEventArgs

Provides event data for the RoleManagerModule.GetRoles event of the RoleManagerModule class.

RoleManagerEventHandler

Defines the delegate for the RoleManagerModule.GetRoles event of the RoleManagerModule class.

RoleManagerModule

Manages a RolePrincipal instance for the current user. This class cannot be inherited.

RolePrincipal

Represents security information for the current HTTP request, including role membership. This class cannot be inherited.

RoleProvider

Defines the contract that ASP.NET implements to provide role-management services using custom role providers.

RoleProviderCollection

A collection of objects that inherit the RoleProvider abstract class.

Roles

Manages user membership in roles for authorization checking in an ASP.NET application. This class cannot be inherited.

SqlMembershipProvider

Manages storage of membership information for an ASP.NET application in a SQL Server database.

SqlRoleProvider

Manages storage of role membership information for an ASP.NET application in a SQL Server database.

UrlAuthorizationModule

Verifies that the user has permission to access the URL requested. This class cannot be inherited.

ValidatePasswordEventArgs

Provides event data for the MembershipProvider.ValidatingPassword event of the MembershipProvider class.

WindowsAuthenticationEventArgs

Provides data for the WindowsAuthentication_OnAuthenticate event. This class cannot be inherited.

WindowsAuthenticationEventHandler

Represents the method that handles the WindowsAuthentication_OnAuthenticate event of a WindowsAuthenticationModule.

WindowsAuthenticationModule

Sets the identity of the user for an ASP.NET application when Windows authentication is enabled. This class cannot be inherited.
