To prevent vulnerable virtual machines from being compromised in the cloud. A multiphase distributed vulnerability detection, measurement, and countermeasure selection mechanism called NICE. Built on attack graph-based analytical models and reconfigurable virtual network-based countermeasures. Attackers can explore vulnerabilities of a cloud system and compromise virtual machines to deploy further large-scale Distributed Denial-of-Service (DDoS). Open flow network programming APIs to build a monitor and control plane over distributed programmable virtual switches to significantly improve attack detection and mitigate attack consequences.
