DDOS attack solution part 4

DDOS attack solution

In the “DDOS attack solution part 3” we have installed the csf firewall to stop the DDOS but still receiving the heavy DDOS attack in that case, simply open the /etc/sysctl.conf  file and make the following changes.

net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_sack = 0


To update the changes run the command, so that new values will be updated.

/sbin/sysctl -p
