Abstract
A compromise detection system protects data centers (DCs) or other providers in the cloud. The compromise detection system can detect compromised virtual machines (VMs) through changes in network traffic characteristics while avoiding expensive data collection and preserving privacy. The compromise detection system obtains and uses periodically-obtained flow pattern summaries to detect compromised VMs. Agent-based detection on predetermined and compromised VMs can expose (using supervised learning) the network behavior of compromised VMs and then apply the learned model to all VMs in the DC. The compromise detection system can run continuously, protect the privacy of cloud customers, comply with Europe's General Data Protection Regulation (GDPR), and avoid various techniques that both erode privacy and degrade VM performance.
