Use Anonymous authentication to allow any user to access any public content without providing a user name and password challenge to the client browser. By default, Anonymous authentication is enabled in IIS 7.
If only selected users should view some content and you intend to use Anonymous authentication, you must configure the appropriate NTFS file system permissions to prevent anonymous users from accessing that content. If you want only registered users to view selected content, configure an authentication method for that content that requires a user name and password, for example, Basic or Digest authentication.
