Abstract

Techniques are disclosed for virtual machine trust isolation in an Infrastructure-as-a-Service (IaaS) cloud environment. More specifically, embodiments of the invention monitor levels of suspicious activity on a particular virtual machine using node agents embedded in each physical node. The node agents transmit activity data to a security and relocation engine. If a virtual machine's suspicious activity levels exceed defined suspicious activity thresholds, the security and relocation engine assigns that virtual machine to a different zone. The zones may have reduced connectivity and/or service levels. This enables administrators to more efficiently respond to security threats in the cloud environment.
