ConceptUsing the BPF (Berkeley Packet filter) toolset combined with the Iptables XT_BPF module enables high-performance packet filtering to address large-scale DDoS attacks. BPF Tools contains a simple set of Python scripts that are used to parse the Pcap file, and others are primarily used to generate BPF bytecode.First, download and install BpftoolsDownload the zip file in Https://github.com/cloudflare/bp

cleaning devices deployed in Beijing and Guangzhou IDCs will be redirected Based on the IP address of the service host of the attacked Shanghai IDCs, all traffic destined for the attacked IP address is redirected to the traffic cleaning device. After cleaning, the traffic is reinjected to the IDC center egress router and forwarded upwards.
When a packet containing the remaining part of the attack traffic arrives at Shanghai IDC, the abnormal traffic cleaning device will clean the traffic accord

Mod_evasive is a DDoS-resistant module for Apache (httpd) servers. For Web servers, it is now a good extension to protect against DDoS attacks. Although it is not completely defensive against DDoS attacks, under certain conditions, it is still the pressure to slow down the Apache (httpd) server.
