Example Embodiment
[0015] The present invention will be further described below in conjunction with specific embodiments.
[0016] The DOS / DDOS attack detection method of the present invention first extracts the required flow characteristic parameters, calculates information entropy, and extracts the flow characteristic parameters—determine the abnormal time point—determine the abnormal destination IP—identify the abnormal flow and distinguish the attack type The detection of DoS / DDoS attacks and the identification of abnormal flows are completed in sequence. The specific process diagram is as follows figure 1 Shown.
[0017] It includes the following steps:
[0018] S1. Obtain the flow data in the network from the network equipment, and extract the flow characteristic parameters from the flow data;
[0019] S2. Process the flow characteristic parameters extracted in step S1, determine the abnormal time point, and expand according to the abnormal time point to form a historical time window;
[0020] S3. ...
