Authentication And Authorization

Authentication And Authorization
Authentication is the process of identification and validation of a user's credentials. After the identity is authenticated,
a process called authorization determines whether that identity has access to a particular resource.
ASP.NET provides three ways to authenticate a user:
Forms authentication
Windows authentication
Passport authentication

Setting in web.config file given below

Forms authentication
<configuration>
<system.web>
<authentication mode="Forms"/>
<forms name="login"loginUrl="loginPage.aspx" />
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</configuration>

Windows authentication
<authentication mode="Windows"/>
<authorization>
<allow users ="*" />
</authorization>

Passport authentication
<configuration>
<system.web>
<authenticationmode="Passport">
<passportredirectUrl="loginPage.aspx" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</configuration>
