I recently ran some penetration testing software on my web site and was surprised for it to report that one of my directory listings was publicly accessible.
You could create a .htaccess
file in that directory, or have a <directory>...</directory>
block in your Apache configuration that specifies:
Options -Indexes
See the Apache options directive documentation for more details.
There is a command in Apache that will make it show indexes.
Options +Indexes
Remove this, restart. This will make that url show a 403 Forbidden.
