it should be very simple. all you have to do is to use .htaccess rules if you use Apache to prevent anyone from going there!!

if you want to allow all visitors, use this:

<Directory />
    Order Deny,Allow
    Allow from all
</Directory>

if you want to deny all, but allow only your local address 127.0.0.1, use this

<Directory />
Order Deny,Allow    
Deny from all
Allow from 127.0.0.1
</Directory>

if you want to deny all, use this:

<Directory />
Order Deny,Allow    
Deny from all
</Directory>

if you want to setup a password and username protection, that is different story:

Order deny,allow
Deny from all
AuthName "Restricted Area - Authorization Required" 
AuthUserFile /your/file/path/.htpasswd 
AuthType Basic
Require valid-user
