| The rapid development of computer and communications technology make the network become an important component of people’s work and life. Computer communication in working has brought us convenience, but also brought risks which cannot be ignored:information loss, damaged, cyber attacks, viruses and so on. With a series of painful lessons, people are increasingly aware of the importance of network security. Network security management system is used to solve these problems. It can work well on the LAN to monitor the work of the hosts and various security devices. However, the traditional network security management system cannot meet the increasing needs of storage and processing of massive data business.In this paper, to solve the demand for the new system with the current trends, we propose a new scheme, the design of network security management system based on hadoop:1, the use of hadoop cluster overall storage capacity and combination with traditional network security management system relational database to store data will replace its original single data storage model which can not solve the problems like storing large amounts of data safely and consistently.2, the use hadoop cluster parallel computing capabilities and combination with traditional business processes of network security management system will solve the problem that a single server cannot process massive data quickly.This system includes devices management module, event dealing module, security check module and data backup module. Devices management module is used to monitor all the devices in the network includes secrurity devices, working hosts, reliable devices and unknown devices. Event dealing module is used to receive all the data transferring to system server and play these information to user. Security check module judges the situation of the network using all the data system had with determined rules. We build a data ceter using data backup module and hadoop cluster to keep all the data safe. |
