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.
I do use it quite a lot. The pfSense package for ACME can run scripts, which might use scp. Modern Windows boxes can run OpenSSH daemons and obviously, all Unix boxes can too. They all have systems like Task Scheduler or cron to pick up the certs and deploy them.
