One should use windows authentication, wherever it is possible. Because Windows Authentication uses the active directory or similar structure to store the user name and passwords, and we need not to create password policies and password encryption to store them in database.
This object internally implements the System. IIdentity interface to represent the authenticated user. We can access the authenticated user through HttpContext. IIdentity regardless of authentication method, whether it is Forms authentication or Windows authentication. In forms authentication, user name and password combination are stored in database or configuration file. The user provides the credentials and that are validated against these stored credentials. We should use Windows Authentication where it is possible.
Because by windows authentication we are having the benefits of Active directory, enforceable account and password policy and one centralized storage of credentials. For making Secure Windows authentication we can consider the followings:. Where possible, you should use Windows authentication because this enables you to use an existing identity store such as your corporate Active Directory, it enables you to enforce strong password policies, you do not need to build custom identity store management tools and passwords are not transmitted over the network.
There are lots of configuration settings for any ASP. NET web application. These settings are very important for any web application. There is connection string, the most important part for database connectivity. Some times developers directly give database credentials in plane in web.
That is a bad practice, if you are giving the credentials in connection string then we should encrypt the connection string with the help of following command:. By the Data access Security we mean to say that unauthorized illegal access to database should not be provided.
Some hackers may inject the harmful code through forms that can access the database illegally. So every data should be properly validated before submitting it to back end. The first method should be used when there is low user load or number of occurrences of error is less and the second one is used when higher number of concurrent users is there. By code Access Security we mean to say restrict the access to system resources which our code may do, and the type of privileged operations that our code may do.
These restrictions are independent of user who calls the code. For using the code access security we should consider the following guidelines:. Step 3 : Select the authentication type to 'Forms based authentication' by selecting the 'From the Internet' radio button. Step 4 : Click on 'Create Users' link to create some users.
If you already had created roles, you could assign roles to the user, right at this stage. Step 6 : Place a LoginStatus control on the Welcome. It has two templates: LoggedIn and LoggedOut. In LoggedOut template, there is a login link and in the LoggedIn template, there is a logout link on the control. You can change the login and logout text properties of the control from the Properties window. Here, you can put texts and other controls hyperlinks, buttons etc. This control has two view templates: Anonymous template and LoggedIn template.
Select each view and write some text for the users to be displayed for each template. The text should be placed on the area marked red. Step 8 : The users for the application are created by the developer.
You might want to allow a visitor to create a user account. For this, add a link beneath the LoginView control, which should link to the CreateAccount.
Step 9 : Place a CreateUserWizard control on the create account page. Step 10 : Create the Login page. Place a Login control on the page. The LoginStatus control automatically links to the Login. To change this default, make the following changes in the web. When you begin a program for a customer using ASP. Net, you should consider about security. Security is one of the most important components of any application. Security is even more important when you are making a web application which is exposed to million of users.
In this article we will investigate the different types of authentication provided by ASP. In web. What's about difference and how to you use them?
Authentication have some other values to, this article does not consider them. NET application to use window-based or forms-based authentication. Windows Authentication mode provides the developer to authenticate a user based on Windows user accounts. This is the default authentication mode provided by ASP. You can easily get the Identity of the user by using User. This will return the computer name along with the user name. Windows authentication also provides IsInRole method to find the role of the user and than you can give permissions to the user depending on the role.
Other you can make a special client to access you project with windows authentication. Code like this this case you can get value using 'User.
Name', then you can use it to do other work you like.
