If you want to prevent others from accessing the logaholic reports,
you need to password protect the logaholic directory.

The best way to do this is to use the .htaccess and .htpassword
authentification provided by Apache.
For manual instruction on .htaccess, please view:
http://httpd.apache.org/docs/1.3/howto/htaccess.html

An easy tool that will generate what you need can be found here:

If you are using Microsoft IIS, you can add a password via the IIS
manager.

If you are on a hosted solution with cpanel or another 'manager' interface,
there should be an easy option to add a password to a directory.
