Default installation files on xxx.xxx.xxx.xxx
Hi,
One of your server xxx.xxx.xxx.xxx
serves default Apache files.
While this does not represent a real security issue, it's always a good practice to remove default installation files. Certain files could reveal important informations about your system and could be used by a malicious user for a future attack.
Disable or remove default installation files on production servers.
