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.
The alternative is you could use a Windows server… Bear in mind a lot of code for windows is private and isn’t open to scrutiny from the public so chances are there could possibly be built-in backdoors no one is aware of except for Microsoft or there are backdoors which are only known to a hacker who’s discovered them.
The recent xz backdoor, I think is a stellar example of how powerful open source software can be, a community came together and noticed this in such a short period of time and had a way to quickly resolve this without this being a large scale issue, looking back at things like Log4j which caused so much pain across the entire industry, we are so lucky to have open source software communities.
