Abstract


As the Internet increasingly open, as well as the rapid development of network technology, accompanied by network attacks are getting more and more serious, the issue of network security has become a very hot topic, attention is gradually being. The traditional static security defense system, such as firewalls, authentication and data encryption technologies are relatively mature, there are some defects, however, still can not completely solve the current network security situation. So, intrusion detection (IDS) technology came into being. Intrusions can found traces of the intrusion and the law, to make up for the deficiencies of the traditional security technologies, is a dynamic network security system, a firewall after a security perimeter. The face of an increasingly complex and large network environments, distributed intrusion detection technology to become one of the current intrusion detection technology trends. This article from the overall design of a distributed intrusion detection system, a detailed analysis and discussion, and focus on the achievement of the Distributed Intrusion Detection System Control Center features, including user interface design, user management, detectors management log management, intrusion response. Distributed Intrusion Detection System, the huge number of alarm information systems analysts face of such data is often impossible to start. IDS is generally only concerned with low-level attacks and anomalies, and each produces its own alarm information, lack of coordination specification to each other, can not capture the logical steps to hide behind these attacks and strategy. In view of this situation, this article has designed an information fusion model filter processing repeat the alarm information, alarm information merge processing through experiments that the information fusion technology can effectively streamline the alarm information to reduce information redundancy , which can be brought to the administrator. In addition, with the development of intrusion detection technology, a growing number of IDS adopted a proactive approach to resist attacks such as discarded suspicious data packets isolated node of attacks, reconfigure the network environment. In this paper, on the basis of existing active response technology, combined with the response to the invasion of the cost analysis and response strategy selection, design an intrusion response decision-making model and operational decision-making based on quantitative criteria, the model for intrusion response steps and methods.
