The Design And Realization Of Network Information Security Monitoring System

With the fast development and the widely application of Internet, the network information security is more and more important and becomes main subject related with national security and society welfare. Traditional network information security technologies belong to static defensive technology. If we purely depend on these technologies, it is difficult to ensure the security of network. Therefore, we put forward the network information security monitoring system; it will be used widely as an important element of the integrality of dynamic network security prevention infrastructure.The main research in this thesis is the design and realization of network information security monitoring system. Firstly, we analyze the background of the network information security, the current status and developing trend of this research, especially analyze the significance of the network information security monitoring system; secondly, briefly introduce the basic principle of the network information security monitoring system, and based on in-depth research in correlative knowledge and technology such as intrusion detection, computer system log and so on, we present the design idea of the network information security monitoring system by conducting requirements analysis, elucidate main architecture and design module; thirdly, we primarily explain the design and coding implementation of the network information security monitoring system key module, and describe the implementation process; finally, we summarize the test circumstance and give the result.
