Answer 3

My website has been maliciously requested before. I used iptables to block the URL.
iptables -t raw -A PREROUTING -i eth0 -p tcp --dport 80 -m string --from 0 --to 100 --algo bm --string "GET /ddos_url/" -j DROP
roughly means: If the 0--100 characters of the request packet include "GET /ddos_url/", then it will be intercepted. In this case, any request for that URL will be blocked by the firewall.
iptables-nvL -t raw View the number of intercepted requests.
