Securing Xymon Over Internet

Hi XyMonsters!

 
I need to monitor several satellite sites with XyMon. These sites are
not available on our local LAN so I have to go via the internet. I am a
bit hesitant to open the ports etc since the information collected can
be used in foot printing the system. How would I go about securing the
service so that xymons information does not fall into the wrong hands?

 
Regards

Neil
