I have been thinking about self-hosting my personal photos on my linux server. After the recent backdoor was detected I’m more hesitant to do so especially because i’m no security expert and don’t have the time and knowledge to audit my server. All I’ve done so far is disabling password logins and changing the ssh port. I’m wondering if there are more backdoors and if new ones are made I can’t respond in time. Appreciate your thoughts on this for an ordinary user.

    Yes, that’s one option. Then you only have to distribute the certificates and keys.

    Or you allow remote access to that DNS server (Bind has a secure protocol for this), do the challenge requests and cert generation on some other machine. Depends on what is more convenient for you (the latter is better if you have lots of machines/certs).

    Worst case if someone compromises that DNS server they can only generate certificates but not change your actual valuable records because these are not delegated there.
