Edit the file httpd.conf.

 

1. Add the following Apache directive, if it's not yet set :

HostnameLookups On

This directive allows PHP to know the origin (countries) of the visitors requests.

 

2. You should also remove the automatic listing of directories :

<Directory /var/www/>
  Options -Indexes FollowSymLinks MultiViews
</Directory>

 

3. Deny access to the log files :

<Files ~ "\.log$">
  Order deny,allow
  Deny from all
</Files>

 

4. Deny access to the sushee cache files, by placing a .htaccess containing :

<FilesMatch "^cache">
Order Deny,Allow
Deny from All
</FilesMatch>
<FilesMatch "^tmp">
Order Deny,Allow
Deny from All
</FilesMatch>
<FilesMatch "^pdf">
Order Deny,Allow
Deny from All
</FilesMatch>

 

into the sushee "Files" directory.

 

 

Don't forget to restart Apache :

/etc/init.d/httpd restart

The path to restart Apache can vary and depends on the Linux distribution you are using. It can also be:
/etc/init.d/apache restart
or
/etc/init.d/apache2 restart
