Secure connection between drupal & piwik

Hi,
I use drupal and piwik. In drupal I just enter the path to the piwik installation and piwik gets the data from drupal. How do I make a secure connection between the both programms? I dont want than anyone can access the data.

Many thanks

I think, if you enter only a https URL to Piwik, all information should be sent over SSL-encrypted connections and should be very secure. At least as secure as you can get something on the WWW.
