I, recently, started running a Lemmy instance. I am, also, new to Linux servers.

At the advisement of some tech acquaintances, I’ve installed UnnattendedUpgrades and Fail2ban.

What would you recommend?

    Don’t allow root ssh access, you could also change the ssh port to one that’s not 22. Also you could disallow ssh password login and allow key-based authentication only.

      Also try to set it up without installing sudo , which will eliminate a lot of privilege escalationvulnerabilities.
