Secure Server From DDos Attacks via CSF

[azadhussnain]

Hello, actually i seen a website providing DDos as service for just 2.99$ for 2 Days -_- with 10 Gbit/s Speed.
For test, i done DDoS on my server and it does down !
I'm surprised to see, in just 3$ anyone can down our server for two days.
They have theses DDoS Methods :
UDPMIX
DOMINATE
DNS
ACK
ACKX
and maybe 1-2 more, i didn't checked correctly. The Attack is a layer 4 attack.

Is there any method to stop such attacks affecting our server? Via CSF can we protect our server against these attacks ?

Hi,

You could use Cloudflare, as well as CSF.

See Cloudflare DDoS Protection | Intelligent DDoS Mitigation | Cloudflare and https://haydenjames.io/replacing-cloudflare-with-csf-firewall-install-guide/ for more information.

Hello azadhussnain! In some research, I found that CSF can be used for DDoS mitigation, although it appears it is only effective against smaller attacks.

You can essentially use CSF to rate-limit traffic. More on this can be found here.

Otherwise, you may wish to utilize a service specialized in DDoS protection\, such as Cloudflare, as ZenHostingTravis mentioned.
