Application Of Distributed Intrusion Detection Technology In Electronic Commerce

With the rapid development of computer technology and network technology,application of computer network technology is increasingly linked with people's social life.Application of computer network technology has brought great convenience to people's work and life, and network security also becomes the main problems, which people now must solve. Internet is the operation platform of electronic commerce.Electronic commerce has become an important mode, by which people carry on business and trade activities.Safety is the key problem of electronic commerce and it restricts the development of electronic commerce. So we need build a safe and reliable electronic commerce application environment to ensure electronic commerce activities process become normal and high safe. Firewall is an important method which guarantees the security of electronic commerce.But only a firewall is not sufficient to ensure safety of electronic commerce activities. Distributed intrusion detection system, which can effectively improve the security of electronic commerce, is an important supplementary measure for firewall.This paper first analyzes research background, research situation, development status at home and abroad of the subject.It also deeply researches security situation, safety requirements ,security technology,safety Structure of electronic commerce.This paper secondly researches existing deficiency of distributed intrusion detection theory and distributed intrusion detection technology. It analyzes several key technologies of distributed intrusion detection system ,and on this basis, puts forward adoption of protocol analysis techniques, CBM algorithm,association rules algorithm to improve operation efficiency, data detection accuracy of distributed intrusion detection system,and to reduce the false alarm rate and missed alarm rate. And then, it analyzes the electronic commerce network environment, the goal of safety which electronic commerce needs to achieve. It mainly researches application of distributed intrusion detection system based on snort in electronic commerce. It designed a kind of distributed intrusion detection system based on snort which can improve the safety factor of electronic commerce. Finally, this paper gives specific deployment and primitive realization of this kind of distributed intrusion detection system based on snort which appling in electronic commerce and it analyzes the application results of this kind of distributed intrusion detection system based on snort.
