Abstract: Cloud computing, an emerging computing and service paradigm, where the computing and storage capabilities are outsourced on demand, offers the advanced capabilities of sharing and multi-tenancy. But security has been a major barrier for its adoption to enterprise, as being placed with other tenants on the same physical machine (i.e. co-residency or co-location) poses a particular risk. Former research has shown how side channels in shared hardware may enable attackers to exfiltrate sensitive data across virtual machines (VMs). In view of such risks, tenants need to be able to verify physical isolation of their VMs. This paper presents Sift, an efficient and reliable approach for co-residency detection. Through a pre-filtration procedure, the time for co-residency detection could be significantly reduced. We describe the cloud scenarios envisaged for use of Sift and the accompanying threat model. A preliminary validation of Sift has been carried out in a local lab Xen virtualization e xperimental platform. Then, using the Amazon’s Elastic Compute Cloud (EC2) as the test platform, we evaluate its practicability in production cloud environment. It appears that Sift can confirm co-residency with a target VM instance in less than 5 seconds with an extremely low false rate. (More)
