[Abstract]:With the rapid development of computer and communication technology, computer network is popularizing rapidly in the field of people's work and life. In order to make full use of and share the resources in the network, many enterprises and organizations, Will own the internal network and the Internet connection. However, the following problems of network security are becoming more and more serious. Illegal access from the Internet, malicious attacks and computer viruses emerge in endlessly. In order to deal with the network security problems, enterprises and organizations have deployed firewall, intrusion detection system and other security devices in the internal network, but the results have little effect. The reason is that when dealing with the threat of network security, the security equipment only plays the role of single protection, but the attack means from the network are changing with each passing day, the concealment is extremely strong, it is difficult to find the intrusion behavior by relying on a certain device alone. The lack of the means of information interaction and security linkage between security devices becomes a separate "security island" which can not give full play to the security performance of the equipment. This paper analyzes the current problems in the railway industry, designs and implements a network security monitoring platform based on the B / S architecture, referring to the advanced ideas and schemes of network security supervision at home and abroad in view of the needs of network security. The platform implements centralized monitoring of IT assets in the network, summarizes, filters and analyzes the massive logs from all kinds of network security devices, servers and application systems, and analyzes the security risks from the overall perspective. Form a unified security decision to respond to and handle security events. At the same time, combined with the vulnerability check of the assets themselves, the comprehensive risk assessment of the assets and security domains in the network is carried out to improve the efficiency of the network security management. The research of this paper, following the trend of the development of network and information security, can be applied to the internal network of each road bureau, as its network security monitoring system, it has important practical significance.
