Thi s paper provide s an overview of a configuration of a cloud that was implemented in the authors' laboratory and was broken into three layers: the cloud, zone , and virtual machine. S ecurity mechanisms that were used in the study, including multi - level firewalling, are described . A series of actual port security defin itions within each firewall are included so that the interaction among the three firewalls can be illustrated and analyzed . Finally, we conclude by discuss ing the importance of starting with a sound security policy before configuring the firewall s .
