“…VM Checkpointing and Speculative Execution: Continuous checkpointing of VMs was brought to Xen by Remus [13] for providing high availability by replicating VMs across a data center. SecondSite [29] was built on top of Remus to provide disaster recovery across the wide area. In addition to using checkpoints for crash failures, it has also been studied for recovering from transient errors [38], debugging [19], and performing intrusion analysis [15].…”

Cloud applications are appealing targets to attackers, yet current cloud infrastructures have few ways of helping defend their customers from attacks. However, the use of virtual machines, and the economy of scale found in cloud platforms, provides an opportunity to oer strong security guarantees to tenants at low cost to the cloud provider. We present CRIMES, an evidence based, modular security framework for cloud platforms that uses speculative execution coupled with memory introspection tools to detect malicious behavior in real time. By buering VM outputs (i.e., outgoing network packets and disk writes) until a scan has been completed, CRIMES gives strong guarantees about the amount of damage an attack can do, while minimizing overheads. When an attack is detected, CRIMES rolls back to a recent checkpoint and performs automated forensic analysis to help pinpoint the source of an attack. Our evaluation demonstrates that CRIMES incurs less overhead compared to memory protection tools such as AddressSanitizer, while oering valuable forensic analysis for buer overow attacks and malware detection across multiple applications and the OS.

Disaster recovery planning and securing business processes against outtakes have been essential parts of running a company for decades. As IT systems became more important, and especially since more and more revenue is generated over the Internet, securing the IT systems that support the business processes against outages is essential. Using fully operational standby sites with periodically updated standby systems is a well-known approach to prepare against disasters. Setting up and maintaining a second datacenter is, however, expensive. In this work, we present Cloud Standby, a warm standby approach for setting up and updating a standby system in the Cloud. We describe the architecture of Cloud Standby and its methods for deploying and updating the standby system. We show that by using Cloud Standby the recovery time and long-term costs of disaster recovery can significantly be reduced.
