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 don’t think you need to worry about backdoors with most of those. Worry more about unfixed security holes due to an extreme emphasis on “stability” as in using old versions when fixes have already been released when it comes to anything hosted by large companies.
