In the days when the network is booming, network security issues have become increasingly prominent. Black and white channels on the network are fiercely competitive in various fields of network security. The Black Hat community is constantly introducing new technologies to avoid or bypass Network Intrusion Detection Systems (NIDS). NIDS developers are constantly adding Detection

Intrusion detection System (IDS) is a reasonable complement to the firewall, which helps the security system to detect possible intrusion precursors and deal with network attacks. The intrusion detection system can monitor the network without affecting the performance of the network, provides real-time protection against internal attacks, external attacks, and misoperation, and can extend the security manag
