HTTP Get Flood attack prevention method based on server log

The invention relates to the field of network security in the computer networking technology subject, in particular to an HTTP Get Flood attack prevention method based on a server log. The HTTP Get Flood attack prevention method aims at solving the problem that in the prior art, the CC attack prevention effect is poor when the number of attack source IPs is large. By means of the HTTP Get Flood attack prevention method, protection better in effect is provided for the HTTP Get Flood attack in the CC attacks. Through the combination with whether the IPs of the same requests can feed back feedback responses meeting the requirements, whether an IP is the attack source IP of the HTTP Get Flood attack or not is judged by judging whether the number of IPs of the same requests within the assigned duration in the server log exceeds the threshold value or not through statistics and analysis, and the attack source IP is blocked. The method is simple in design and easy to implement, the method can well adapt to various existing servers and has wide application and popularization prospects.
