Do You Use Antivirus Software or Firewall To Harden Cloudron?

[IniBudi]

I already followed the security guide from Cloudron documentation here https://docs.cloudron.io/security/.

I use 2FA + SSH key for my server, Cloudflare Gateway, Cloudflare WARP, etc.

I wanna ask you about the hardening server that's not covered by the documentation above.

• Do you use software antivirus on Ubuntu Server?
• Would you mind sharing your best practices to harden your server from hacking attacks?

Thank you

I update IPdeny lists (in order to block certain countries) with @imc67 script, see https://forum.cloudron.io/topic/3795/firewall-spamassassin-automatic-list-update?page=3
It's not state-of-the-art security, but the spam and mail server abuse attempts have dropped significantly.
