Abstract

En 中文

Virtualization-based technologies have become ubiquitous in computing. While they provide an easy-toimplement platform for scalable, high-availability services, they also introduce new security issues. Traditionally, discussions on security vulnerabilities in server platforms have been focused on stand-alone (i.e., non-virtualized) environments. For cloud and virtualized platforms, the discussion focuses on the shared usage of resources and the lack of control over the infrastructure. However, the impact virtualization technologies can have on exploit mitigation mechanisms of host machines is often neglected. Therefore, this survey discusses the following issues: first, the security issues and challenges that are introduced by the migration from stand-alone solutions to virtualized environments-special attention is given to the Virtual Machine Monitor, since it is a core component in a virtualized solution; second, the impact (sometimes negative) that these new technologies have on existing security strategies for hosts; third, how virtualization technologies can be leveraged to provide new security mechanisms not previously available.; and, finally, how virtualization technologies can be used for malicious purposes.
