To mitigate the effort to maintain my personal server, I am considering to only expose ssh port to the outside and use its socks proxy to reach other services. is Portknocking enough to reduce surface of attack to the minimum?

    • you also need to know the correct username

    Use a secure password or key. Security by obscurity is no security.

    • audits and logging shows which user used sudo to gain root access

    That is not the point that was made. Once access to sudo or root you already have lost.

      You’re making it that much easier for someone to brute force logging in or to exploit a known vulnerability. If you have a separate root password (which you should) an attacker needs to get through two passwords to do anything privileged.

      This has been considered an accepted best practice for 20+ years and there’s little reason not to do it anyways. You shouldn’t be running things as root directly regardless.

        When you have secure passwords kr key auth. Brute force is not a problem. What vulnerability are you talking about? Complete auth bypass? Then the username would be no problem either since you can just brute force usernames.

      Security though obscurity, BY ITSELF, is not security. But it’s great at slowing attackers and thwarting automated scripts.

      It’s bad security to ignore possible mitigations to a problem just because it isn’t as full fix.
