Design of intrusion detection system oriented to computer network security

With the development of computer network, the protection of network information from various attacks is becoming more and more serious, and has become the basic purpose of network security. However, because of diversity and openness of computer network connection with the terminal and the network distribution of the connectivity characteristics of the system, leading to the computer network vulnerable to hackers, malicious software attacks and other misconduct, network security has become a key factor restricting the development of the network. Therefore, it is necessary to carry out the comprehensive research of intrusion detection.
