I am (to be) a web designer, how to ensure security on a vps?
See https://github.com/fail2ban/fail2ban for beginner's guide, basically you set it up to monitor logfiles and it would act accordingly (plenty of built-in config to handle various daemons so you don't have to write yourself).

Home Lab Setup Recommendations

fail2ban not notifying Cloudflare
— In /etc/fail2ban/action.d/cloudflare.conf I copied the file from https://github.com/fail2ban/fail2ban/blob/master/config/action.d/cloudflare.confand added my ‘cftoken’ and ‘cfuser’ on the bottom

Firewall rules beyond "deny incoming, enable only the ports that you need"
https://github.com/fail2ban/fail2ban is a mature, easy to set up way to have some dynamic firewall rules that respond to attacks. There are more sophisticated options, but they are probably not worth the return on time investment for you.

Ask HN: How to monitor the security of a personal VPS?
OSSEC is good for monitoring logs, system files, etc. as well as alerting (and blocking traffic if you want) when anything suspicious happens
Takes a bit of work to set up but is worth it and includes lots of basic checks by default

Passive log analysis software
It's been a long time since I tried using OSSEC but maybe that would help. It's a Host-based IDS, rather than a network based IDS like Snort. Last time I checked you could point it towards your logs and it will parse them offline similar to how Snort can read a PCAP file.

Free EDR solutions
Not sure if it could be considered one but maybe OSSEC Host Intrusion Detection System might get you some.of the way can be found here

Intrusion detection software?
WAZUH (fork of OSSEC would be my first choice when it comes to Linux based HIDS (host based), and Snort or Suricata if you are looking for NIDS (network based). As well as Lynis for ensuring the setup of the host is as you intended.
