When a web browser is pointed to a directory on your web site which does not have an index.html file (or any other index file) in it, the files in that directory can be listed on a web page.

To disable or prevent the directory access add following line in your .htaccess file. If user points the browsers to a directory which does not have index file then in this case 403 error will be
Options +Indexes # or # IndexIgnore *
