High-speed WLAN Key Technologies Of Intrusion Detection

With the popularity of Internet and development of the world, more and more people can stay at home through the Internet to share information resources. Computer network and people's lives have been closely linked, as an integral part of all life. However, with the deepening of network security, network security issues before the increasing number of intrusion detection as an effective security technology, more and more attention by everyone.Intrusion detection technology is in the traditional security measures after the emergence of new security technology. Intrusion detection and computer network resources on the computer attack and intrusion suffered by the protection, intrusion detection of its external but also internal monitoring unauthorized activity on network security play a very important role. For now, intrusion detection systems are not mature and improve, more detailed further enhance the intrusion detection system now has great significance. Background paper for the current work carried out as follows:⑴WLAN security status of the overview. The current research situation, main problems, development prospects were analyzed.⑵From the security aspects of intrusion detection, security, algorithms and the development trend of studies for intrusion detection systems and the application of pattern matching algorithms, paving the way research.⑶The key technologies of intrusion detection research, in the original BM algorithm based on improved, an improved pattern matching algorithm and the proposed method and other pattern matching algorithms to compare and contrast.⑷Intrusion detection system for the existing problems in its analysis and design, design a multi-Agent Intrusion Detection System.⑸Analog simulation of intrusion detection systems. Through the packet loss rate detection, the article mentioned in the Snort intrusion detection system and intrusion detection systems were compared. Data obtained by this intrusion detection system designed with a smaller packet loss rate characteristics. Proved, Agent mechanism and improve the algorithm, to better improve the detection speed, to enhance the intrusion detection system has better ability.
