Research on the system model of network intrusion detection

Abstract

With the rapid development of the network, network security has become one of the most important issues, as it directly affects the interests of the state, enterprises and individuals. Further more, with the increasingly mature of the attack knowledge, complex and diverse attack tools and techniques, the current simple firewall technology has been unable to meet the needs of the people. Facing so many challenges and threats, intrusion detection and prevention technology is bound to become one of the core technologies in the security audit. The iintrusion detection, playing a role of active defense, is an effective complement to the firewall, and is an important part of network security. This paper mainly analyzes the decision tree algorithm and improved Naive Bayes algorithm, proving the effectiveness of the improved Naive Bayes algorithm. © 2013 Springer-Verlag.
