Network Anti-attack Analysis And Testing Of Cloud Computing Data Centers

The rapid development of cloud computing promoted the transformation of data centers.Cloud computing data centers differ from traditional data centers mainly in large-scale networking, virtual machine migration and multi-tenant shared network resource pool. With the widespread use of cloud-box model, the cloud computing data centers not only greatly facilitates people's lives, but also maximizes the use of limited resources. So to say, the cloud computing data centers has a broad development prospects. Along with the popularity of cloud computing data centers, the network attack preventions are increasingly valued.This paper starts from the conception of cloud computing. Thereafter, the advantage of cloud computing in computing model is analyzed compared with centralized processing model and distributed processing model. After the development of cloud computing, data centers as the core of cloud computing must be able to enhance capabilities of processing and exchanging data to meet the high demand of multi-service cloud computing. At the same time,the data center network security has become a focus of attention. Faced with the new situation that network attacks happened in cloud computing data center, the status and characteristics of network attacks is stated, which pave the way for later research.Besides, for the common network attacks in Ethernet, the paper explains the working principle of protocol, and analyzes the way of attack under different protocol.Finally, different kinds of preventing methods are elaborated, furthermore, combined with test experience, the performance of difference prevention in the experiment are compared.In addition, the article, compared to the traditional data center networking, describes the architecture, network characteristics and networking technologies required for cloud computing data centers. After fully understanding the cloud computing data center and analyzing the requirements of task, the emphasis, difficulties, as well as precautions are given.Afterwards, several kinds of network attacks in cloud computing are simulated based on data center model. Simultaneously, the stability of the common network attacks and new features under the cloud data center are tested. Each section is accompanied with analysis and measurement instructions. Finally, the introduction of the TCL scripting language help to develop automated test modules for the MDC features of cloud computing data centers.
