[0038] Such as figure 1 As shown, the DDoS defense system includes a control module 10, a system monitoring module 20, and a system processing module 30, wherein the control module 10 is responsible for starting, initializing, suspending and closing the defense system, and the initialization setting of the defense system includes abnormal times SYN Packet rate threshold, ACK_SYN packet rate threshold, UDP packet rate threshold, abnormal times threshold, the initialization setting of the defense system may also include monitoring interval time and monitoring duration.
[0039] System monitoring module 20 is used for monitoring system network port, monitors the sending and receiving of data packet, if current process sends to the SYN bag of same IP address same port, ACK_SYN bag or UDP packet rate exceeds rate threshold value, then starts system processing module 30 , and transmit the abnormal process data to the system processing module 30.
[0040] The system processing modul...
