متن کاملSecurity of OS-level virtualization technologies: Technical report
The need for flexible, low-overhead virtualization is evident on many fronts ranging from high-density cloud servers to mobile devices. During the past decade OS-level virtualization has emerged as a new, efficient approach for virtualization, with implementations in multiple different Unix-based systems. Despite its popularity, there has been no systematic study of OS-level virtualization from...
متن کاملTransparent Protection of Commodity OS Kernels Using Hardware Virtualization
Kernel rootkits are among the most insidious threats to computer security today. By employing various code injection techniques, they are able to maintain an omnipotent presence in the compromised OS kernels. Existing preventive countermeasures typically employ virtualization technology as part of their solutions. However, they are still limited in either (1) requiring modifying the OS kernel s...
متن کاملOS Virtualization Security
Recently, people have begun to use OS virtualization as a tool for improving LAN security. While virtualization is very useful in optimizing hardware utilization, we show that its security benefits come at a price.
متن کاملUsing Hardware-Assisted Virtualization to Protect Application Address Space Inside Untrusted Environment
In this paper we present a virtualization-based approach of protecting execution of trusted applications inside potentially compromised operating system. In out approach, we do not isolate application from other processes in any way; instead, we use hypervisor to control processes inside OS and to prevent undesired actions with application resources. The only requirement for our technique to wo...
متن کاملEnabling Virtualization on Scalable Multicore Systems
Current trends in computer architecture encourage rethinking of the system software design principles. Recent research on operating systems (OS) indeed confirms that the scale, diversity and associated complexities of the emerging hardware represent a tremendous challenge. However, as the traditional OS design techniques get influenced by the modern hardware, virtualization being a well-establi...
