Benefits of the virtualization technologies with intrusion detection and prevention systems

摘要

In recent years, virtualization technologies were settled faster than anyone imagined and got placed big areas in our lives. Virtualization is a technology that eliminates the “uniqueness” dependency by creating an abstraction layer between the hardware and the software that runs on it. The aim of virtualization is to centralize the information system for facilitating administrative task while improving scalability. Virtualization technology which allows more efficient use of existing physical hardware, as well as some advantages including cost reduction, labor loss and performance improvement, contains several innovations in security, especially in system security. Software applications such as antivirus, firewall, end point security installed on the servers to ensure system security causes performance loss on the network and servers. Hence, security applications must be implemented on virtualization layer (hypervisor, Virtual Machine Monitor) to cover all the virtual system. In this paper, we aim to explain usage of Intrusion Detection Systems and Intrusion Prevention Systems in virtualization technologies and prologue possible security threats in virtual area.
