    Not sure relying on podman alone as a security tool might be advisable. Podman is a container technology first, security is not the main goal.

    Read more about rootless docker here.

      I never said I was relying on it alone. Not sure why you think that.

      That’s a great link. Thank you for sharing. It’s good that docker supports this functionality now.

        I never said I was relying on it alone. Not sure why you think that.

        …all my services aren’t running as root.

        If it turns out a vulnerability is discovered in lemmy tomorrow that allows people to access my server through my lemmy container, the attacker will only have access to a dummy account that hosts my containers.

        This was your argument according to you for why you think podman is more secure (than docker I presume). Seemed to imply rootless podman will save you from an attacker. I was simply disproving the flawed notion.

          I think you’re interpreting too much. Security is about layers and making it harder for attackers, and that’s exactly what using a non-root user does.

          In that scenario, the attacker needs to find and exploit another vulnerability to gain root access, which takes time - time which the attacker might not be willing to spend and time which you can use to respond.

            You don’t know enough about security to lecture me. The kernel has before/continues to suffer(ed) from successful root shell exploits, particularly in this case via unprivileged userns. Something podman or even rootless docker can’t do anything about.

              Funny how you claim to know so much about security but can’t even seem to comprehend my comment. I know root shell exploits exist, that’s why I wrote that it takes additional time to get root access, not that it’s impossible. And that’s still a security improvement because it’s an additional hurdle for the adversary.

                the person you are replying to either lacks comprehension or maybe just wants to be argumentative and doesn’t want to comprehend.

                Containers cannot be viewed as security tools. They suffer from poor isolation and inadequate and some cases non-existent sandboxing. All these are proven security essentials. You would know about them if you knew anything about (defensive) security!

                  Once again, you’re going off on an unrelated tangent. If you don’t want to listen, I can’t help you. We’re done here.
