The Application Of Network Intrusion Monitoring System In Library Internet

As the network of modern libraries in the extensive use of the function and role of modern libraries than in the traditional sense of the library has undergone great changes. Modern Library with network technology, not only provide traditional book lending, it also provides a large number of network storage and e-resource access. How to protect the library's network security is the library community need to be studied and resolved one important issue, as the library's technical staff, through awareness of the importance of network security, enhance awareness of prevention through learning and study new network security technology, fully understand and study the invasion and intrusion detection technology, knowledge, learn how to network intrusion prevention, and strengthen preventive measures, in order to ensure the daily operations of the library work, protect critical business data and enrich the core of information resources for faculty and research to provide continuous information services.This major work and research is to intrusion detection technology in library network system. Paper to do the following work:from today's network security problems in examining the feasibility of network security protection-related knowledge and technology; to common network attacks means of analysis and research, and gives a defensive approach; right intrusion detection system, and deficiencies in the status quo were introduced; an emphasis on network-based intrusion detection model, a detailed analysis, combined with Winpcap packet capture technology for network intrusion detection system strengths and weaknesses were analyzed, and as a basis to build a library of intrusion detection systems; the basis of existing technologies, combined with the library network has its own characteristics, the network behavior theory and web-based intrusion detection technology combined network of libraries are often subjected to the types of attacks are summarized and analyzed. The network intrusion detection system includes:data acquisition module, statistical analysis module, analysis module, management module 4. The system's main function is to achieve the targeted attacks caused by anomalies in network traffic can significantly detect abnormal changes in data traffic, and based on this right of youth Management College, Shandong Province, the library computer network system of the experimental study, the adoption of the model applications, can detect several common attacks, For the further research and laid the foundation for practical work.
