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.
unfortunately, mass attacks happen all the time. if you ever had access to the authentication logs of an SSH server with an unfirewalled port 22 into the internet that has been running for a few months, you would see international IPs starting port scans and brute force attacks. there is always someone out there trying to hack random IPs. it’s fucking wild west out there.
Yeah. I’d recommend using ssh keys and disabling password authentication whenever something is exposed to a public network
