Design And Implementation Of Security Managenent System Frame Based On NGINX

With the continuous development of Internet technology,the use of the network has been throughout all aspects of people's lives.At the same time,network security issues are endless.Especially for enterprise-class networks,once the network security incidents,will produce incalculable losses.A network security management platform for enterprise-level users can prevent network security problems occur,you can integrate the management of various types of safety equipment from different vendors,different positions,different forms of network devices,security devices and host terminal equipment,other assets unified integrated management,to protect the enterprise network information security.However,security management platform manages all types of assets from different vendors,these assets have different functions,different communication protocols,different data formats.Asset management of security management is realized by the background,so we need a compatible background framework for these assets.Moreover,with the growing security management system,and the increasing in assets and cascading series of access,communications pressure will also increase,so the security management needs to be able to cope with high concurrency pressures too.Based on the new demands,after extensive research,we chose the Nginx,which is a very lightweight HTTP server,this paper designed and implemented a background framework Nginx based network security management platform:1)We proposed a design scheme of network security management platform backstage framework in the core of Nginx,and We designed the entire security management system backend system based on this framework,achieved background program,completed the asset management module,event management module,state management module,achieved the security management platform for all kinds of assets management.2)The solving ability of security management platform high concurrency issues on a single server is limited,so it is necessary to expand the framework of security management background.In this paper,Nginx load balancing strategy has been improved,a dynamic load balancing algorithm WRR has been presented and implemented.The algorithm combines the advantages of WRR algorithm and Fair algorithm in Nginx,the real-time performance of backend nodes was considered.Based on this algorithm,the security management server cluster has been achieve,single server background architecture extend to server cluster architecture,which makes security management can effectively cope with high concurrency.The security management functions were tested.Experiments show that security management system complete for unified management functions across asset.Based on the real security management environment we did a test between Nginx weighted round-robin algorithm and a new dynamic weighted round robin algorithm comparison,the results show that the new dynamic load balancing algorithm makes the response speed and stability of the system improve.
