From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do we know if there aren't a bunch of more undetected backdoors? (lemdro.id)

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.

We don't. That's why we use multiple layers of security. For example keeping all services accessible only via VPN and using a major OS that a lot of production workloads depend on such as Debian, Ubuntu LTS or any of the RHEL copycats. This is a huge plus of the free tier of Ubuntu Pro BTW. It's commercial level security support for $0. Using any of these OSes means that the time between a vulnerability being discovered, patched and deployed is as short as possible. Of course you have to have automatic security updates turned on, unattended-upgrades in Debian-speak.
