9.1 What is the difference between authentication and authorization?
|
 
 |
|
Authentication is the process of identifying and verifying who the client
accessing the server is.
For example, if you use
-
Windows authentication and are browsing an ASP.NET page from server --
ASP.NET/IIS would automatically use NTLM to authenticate you as
SYNCFUSION\user1 (for example).
-
Forms based authentication, then you would use an html based forms page to
enter username/password -- which would then check a database and authenticate
you against the username/password in the database.
Authorization is the process of determining whether an authenticated user has
access to run a particular page within an ASP.NET web application.
Specifically, as an application author decide to grant or deny the
authenticated user "SYNCFUSION\user1" access to the admin.aspx page. This could
be done either by explictly granting/denying rights based on the username -- or
use role based mappings to map authenticated users into roles (for example: an
administrator might map "SYNCFUSION\user1" into the "Power Users" role) and
then grant/deny access based on role names (allowing a degree of abstraction to
separate out your authorization policy).
|
9.2 How to implement authentication via web.config?
|
|
|
Include the <authorization> element.
|
9.3 How to run a Web application using the permission of an authenticated user?
|
|
|
Use the <identity> element in the web.config
|
<identity impersonate="true"/>
|
9.4 Which are the different ASP.NET authentication modes?
|
|
|
ASP.NET supports the following Authentication Providers
-
Windows : Is used in conjunction with IIS authentication. Authentication is
performed by IIS in one of three ways: basic, digest, or Integrated Windows
Authentication. When IIS authentication is complete, ASP.NET uses the
authenticated identity to authorize access
-
Forms : The user provides credentials and submits the form.
-
Passport : Centralized authentication service provided by Microsoft that offers
a single logon and core profile services for member sites.
-
None : No Authentication provided. This is default Authentication mode
In the web.config file, you can specify this setting:
|
mode= " [ Windows | Forms | Passport
| None ] ">
|
9.5 How to determine the Windows User from a Web form Application?
|
|
|
Use the System.Security.Principal namespace.
VB.NET
|
dim wp as WindowsPrincipal = new
WindowsPrincipal(WindowsIdentity.GetCurrent())
|
Response.Write(wp.Identity.Name)
|
WindowsPrincipal wp = new
WindowsPrincipal(WindowsIdentity.GetCurrent());
|
Response.Write(wp.Identity.Name);
|
9.6 After installing SP4 none of my ASP.NET pages developed using Framework 1.0
are showing the errors related to security?
|
|
|
To resolve this issue, identify the user account that is used to run the
program, and then assign the "Impersonate a client after authentication" user
right to that user account. To do this, follow these steps:
-
Click Start, point to Programs, point to Administrative Tools, and then click
Local Security Policy.
-
Expand Local Policies, and then click User Rights Assignment.
-
In the right pane, double-click Impersonate a client after authentication.
-
In the Local Security Policy Setting dialog box, click Add.
-
In the Select Users or Group dialog box, click the user account that you want
to add, click Add, and then click OK.
-
Click OK.
