Unauthorized access to client is a potential security risk, and we recommend that you prevent access to it on all instances where you do not need it.

You can restrict access to the client in the following ways:

  • Disable IIS anonymous access

  • Disable Forms authentication

  • Deny access to the Copyrights folder

Disable IIS anonymous access

To restrict access to the client, disable IIS anonymous access:

  1. Open the IIS Manager application.

  2. To see a list of all you IIS websites, in the Connections pane, double-click the name of your server and then double-click the Sites icon.

  3. Double-click the website of the role you want to configure.

  4. Click the first folder or file from this list:

    • <webroot>\App_Config\

    • <webroot>\sitecore\admin\

    • <wwwroot>\sitecore\debug\

    • <webroot>\sitecore\login\

    • <webroot>\sitecore\shell\

    • <webroot>\sitecore\default.aspx

    • <webroot>\sitecore modules\debug\

    • <webroot>\sitecore modules\Shell\

    • <webroot>\xsl\


    To select a file instead of a folder, right-click the role website and click Switch to Content View to see the website files. Then click the file, right-click the role website again, and click Switch to Feature View.

  5. In the center application pane, in the ASP.NET section, double-click the .NET Authorization Rules icon.

  8. Repeat steps 5 to 7 for all the listed folders and files in step 4.

  9. In the Connections pane, click the name of your server.

  10. To restart IIS and activate your configurations, in the Actions pane, in the Manage Server section, click Restart .


This procedure creates a directory-specific web.config file for each folder and file. If you prefer to keep all your configurations in the application-specific <wwwroot>\Web.config file, see the Microsoft documentation on How To Make Application and Directory-Specific Configuration Settings in an ASP.NET Application.

Disable Forms authentication

If you disable Forms authentication, Sitecore will not handle any requests for authentication.

To disable Forms authentication:

  1. Open the <webroot>\Web.config file.

  2. Locate the authentication node.

  3. Change the mode attribute from Forms to None.

    <authentication mode="None">

Deny access to Copyrights folder

The sitecore/Copyrights/ folder on the CD server contains license text files for all third party components that Sitecore uses. A user can construct a URL that gives access to these files. You can configure Sitecore to deny access to this folder on the CD server.

To deny access to the folder:

  • Add the following setting to the handlers section of the web.config file on your CD server:

    <add name="StopSitecoreCopyrightsDirectoryBrowsing" path="sitecore/Copyrights/*" resourceType="Directory" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" />
