Abstract
A firewall dynamically adapts to changes in a utility computing system. The utility computing system has multiple nodes that are dynamically provisioned in different roles. The different roles are best served by different security and/or Quality-of-Service (QoS) policies. The firewall selects and applies security and/or QoS policies to a node or group of nodes based on the roles provisioned to the node or group. The firewall detects when the provisioning of a node changes, and dynamically applies a new security and/or QoS policy to the node based on the new provisioning. The firewall thus provides adaptive network-level security and QoS functionality to a utility computing system.
