  1. ASP.NET SECURITY Presenter: Van Nguyen

  2. Introduction Security is an integral part of any Web-based application. Understanding ASP.NET security will help in building secure Web applications. This document provides a brief overview of security in ASP.NET.

  3. Introduction • ASP.NET Web application security • FormsAuthentication • Manager Users Using Membership • Managing Authorization using Roles

  4. I. ASP.NET Web application security • ASP.NET architecture • ASP.NET Data Flow • ASP.NET Authentication • ASP.NET Authorization • ASP.NET impersonation

  5. I. ASP.NET Web application security • ASP.NET architecture

  6. I. ASP.NET Web application security • IIS Security • Anonymous • Basic • Digest • Integrated Windows Authentication • Certificate

  7. I. ASP.NET Web application security • ASP.NET Data Flow • The security data flow for two common scenarios: • Impersonation. • Forms authentication using cookies.

  8. I. ASP.NET Web application security • ASP.NET Authentication: • Authentication is the process of obtaining identification credentials such as name and password from a user and validating those credentials against some authority. • Windows Authentication Provider. (Asp.net Impersonation) • Forms Authentication Provider. (FormsAuthentication)

  9. I. ASP.NET Web application security • Authorization determines whether an identity should be granted access to a specific resource. • In ASP.NET Authorization, there are two ways to authorize access to a given resource: • File authorization • URL authorization

  10. I. ASP.NET Web application security • ASP.NET impersonation:

  11. I. ASP.NET Web application security • ASP.NET impersonation: • ASP.NET impersonation is disabled by default. • If impersonation is enabled for an ASP.NET application, that application runs in the context of the identity whose access token IIS passes to ASP.NET. • Web application base on IIS to authenticate users. • Server should provide different Window users for every application to avoid access resource to other web application. • <configuration> • <system.web> • <authentication mode="Windows“/> • <identity impersonate="true"/> • </system.web> • </configuration>

  12. II. FormAuthentication

  13. II. FormAuthentication • Forms authentication uses an authentication ticket that is created when a user logs on to a site, and then it tracks the user throughout the site. The forms authentication ticket is usually contained inside a cookie. • Configuration FormsAuthenticationin web.config:

  14. II. FormAuthentication • Credentials Store in web.config: Forms authentication credentials that are used to validate users at logon can be stored in an external data source or in the application configuration file.

  15. II. FormAuthentication • Logging In, Logging Out using FormsAuthentication. • Logging In: • Logging Out: if (FormsAuthentication.Authenticate(model.UserName, model.Password) || Membership.ValidateUser(model.UserName, model.Password)) { FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe); //FormsAuthentication.RedirectFromLoginPage(userName,isPresistentCookie); } FormsAuthentication.SignOut(); FormsAuthentication.RedirectToLoginPage();

  16. II. FormAuthentication • Understanding Persistent tickets:The forms authentication ticket was always stored in a cookie. So, the decision between using a persistent versus nonpersistent ticket is a choice between using persistent or session-based cookie. • The following code issues a persistent ticket: FormsAuthentication.RedirectFromLoginPage("testuser", true);

  17. III. Manager Users Using Membership • ASP.NET membership therefore helps you manage user authentication in your Web sites. You can use ASP.NET membership with ASP.NET forms authentication by using with the ASP.NET login controls to create a complete system for authenticating users. • Benefit of ASP.NET membership: • Create new user and password. • Using the Login controls in asp.net. • Storing membership information in database. • Authenticating users who visit your site. • Managing passwords (creating, changing and resetting them). • Specifying a custom membership provider.

  18. III. Manager Users Using Membership • Configuration Membership:

  19. III. Manager Users Using Membership • Install DataBase: • Run file C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regsql.exe

  20. III. Manager Users Using Membership • Finish: • Membership class.

  21. IV. Managing Authorization using Roles • Role management lets you treat groups of users as a unit by assigning users to roles. • Role management helps you manage authorization, which enables you to specify the resources that users in your application are allowed to access. • Using RoleProvider to make a custom Role management.

  22. IV. Managing Authorization using Roles • Configuration RoleProvider: • Authorization using Role:
