Research On Protection Strategy And Communication Monitoring Mechanism Of Multi Level Virtual Domain Based On Virtualization Architecture

Virtualization is becoming a hotspot in the field of information technology due to its advantages of efficient use of computer system resources and good isolation mechanism.In order to adapt to the construction of large-scale data centers and the development of cloud computing needs,many network applications are increasingly running in the virtual machine environment.Network virtualization technology provides a multiplexed network interface for different virtual machines running on virtual machine monitors,without compromising the functionality of network I/O devices.With the rapid development of cloud computing,is the cloud computing environment,data privacy protection concerns and concerns.Security and privacy issues inevitably become obstacles to the continued development of cloud computing is all cloud computing service providers face enormous challenges.Network virtualization technology and network communication monitoring and management has always been the research focus of domestic and foreign scholars,such as virtual machine environment,set independent security virtual domain on the entire platform for intrusion detection research,or based on virtualization technology,the network Security Isolated from the operating system to implement security policies outside the operating system to improve network access control.This paper aims to network virtualization operation mechanism for the characteristics of network traffic in the privileged domain monitoring and management,in the provision of restricted access and network monitoring at the same time,so that the configuration and implementation of the strategy more flexible.The research on the operation mechanism and access control strategy of network communication in virtual environment provides the monitoring and management of the network communication under the virtual environment.It can better protect the user privacy data in the cloud computing environment,provide more secure network service,The further popularization and application of virtualization technology and the future development of cloud computing is of great significance.
