Server tune up and DDOS prevention attack set up

Looking for someone to tune up my Plesk server

I have a Plesk server and it seems to have slowed down.

Ionos seem to say it could be something to do with DDOS.

Not full sure what it needs but the below is some info from Plesk.. and a general tune up would be great as it seems ai have some bits slowing different websites down and I believe most of it is server side.

Basically I just want it tuned up. I seem to have very high CPU -FPM usage form one for he websites and some child thing

Notes from IONOS / Plesk

Hello,

I monitored the server and after I reinstalled the ImunifyAV extension, (which you guys have a license for on this server) I couldn't see this process consuming high CPU usage as previously mentioned.

On a different note, I noticed that some php-fpm processes for the website - are consuming a lot of CPU usage.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

63901 edgeand+ 20 0 1332564 802968 17244 R 98.7 9.8 0:38.66 php-fpm

63909 edgeand+ 20 0 1162364 683028 16316 S 87.4 8.4 0:25.09 php-fpm

63908 edgeand+ 20 0 1197048 717272 15832 S 39.5 8.8 0:16.05 php-fpm

I checked for possible DDoS attack on the server as well.

cat /var/www/vhosts/system/__________/logs/access_ssl_log | awk '{print $1}' | sort -n |uniq -c |sort -nr | head -30

The CPU consumption by PHP-FPM processes is caused by a huge number of request to the domain.

Also, checking php-fpm logs we can see a lot of max_children reaching.

# grep -r "server reached max_children setting" /var/log/*php*-fpm* | cut -d' ' -f5 | tr -d ']' | sort | uniq -c | sort -nr

Straight to the point, you need csf, fail2ban, deflate, ClamAV, rkhunter and few other tools. However you have to accept that these tools will only protect ddos on small scale. If you are receiving a heavy DDoS attack Plus
