Design And Implementation Of Attract Detection And Security Protection System Based On Virtual Networking

With the deep development. of Cloud Computing and Virtualization technology, the systems and applications based on them are increasingly widespread, virtual networking system is one of them. Cloud computing and virtualization technology brings more efficient use of resources and more powerful computing capabilities, however, at the same time, we have to face new security. issues of cloud computing and virtualization environments brought. How to solve these problems will be the key to the sustainable development of cloud computing and virtualization technology. Therefore, learning security issues in cloud computing environment has important practical significance.This paper proposes the concept of "Security as a Service", separate the security issues, of cloud computing solutions as a component, which can be provided to cloud computing users who need the security services. In this paper, design and implement attract detection and security protection system based on virtual networking, the system provides two main security services:1. Attract detection and dispose service based on virtual subnet. According to the actual situation, the normal network traffic is modeled as a Poission Distribution Model, and using the chi-square fitting test to do the traffic model match. While detection model with self-learing ability can be adjusted according to real-time traffic conditions, thus improving detection accuracy. The service mainly for network traffic anomaly detection and dispose for the virtual subnet entry node to ensure the security of virtual subnet.2. Resource allocation strategy based on security consideration. It can provide a separate resource allocation strategy for virtual networking system, which mainly consider about the factors such as physical resource load and network location. The allocation strategy is modeled as vector space model, so that the allocation strategy can be quantified. The target is to ensure that when a physical node or virtual subnet exception occurs, it would minimize the influence on other virtual subnet.Attract detection and security protection system based on virtual networking also provides security assessment capabilities. The system can evaluated these two aspects of services and finally give a comprehensive assessment to determin the security level of the whole system.
