Research On NFV Based Security Services System And Application

With the development of network technology, security issues has been paid more and more attention, and security devices is expensive, so individual users will not purchase safety equipment by themselves,security services have their huge potential market, new technologies, such as: cloud computing , virtualization, software-defined networks, increase the popularity of the new network security problems, but also brings new technology solutions.Software-defined security was born in the environment of virtualization, cloud computing, network virtualization. however,software-defined security, only general concepts, like abstraction,automation, orchestration, automatic extensible and API enabled, but the specific composition and structure, different organizations have different understanding and different implementation, so concrete realization of software-defined security architecture will be a lot different,in different program, its characteristics, performance and functionality will be different, we will propose our way of solution, while the major operator also put forward the concept of NFV , using the common server resources instead of special network equipment, to address complex configuration issues, and through a combination of NFV ideas and software-defined security, propose NFV based security service system,and this is the major research in this paper.In summary, for the security services and based on NFV technology,research on NFV security services architecture, and implement security services are the main contents of this article, and forecast the load of Web security scan through neural network algorithm, to achieve a reasonable distribution of resources is the further research. The main contents are as follows:(1) Research on NFV based Security services architecture. In details,describing the NFV security services architecture and one of the applications, mainly for Web security scanning services combined with NFV characteristics, combined with orchestration discuss its services architecture, and based on this architecture, complete verification testament.(2) Complete verification based on the NFV architecture. Mainly for Web security scanning services, the main test results for each load balancing between security devices, through the icon in real time display,showing the load of the device changes(3) With the neural network algorithm to forecast the task load of Web security scan .With the features and characteristics of the task parameters for Web security scanning, combined with BP neural network algorithm, to predict the load of Web security scan task, based on the measurement system to achieve load balancing .Based on this analysis and simulation of neural network algorithm, to verify the validity of the algorithm.
