Should a wheel user that was created to disable root login and secure SSH have the same ownership as root from a security point of view?

No.

Modern Unix systems use user groups to control access privileges. The wheel group is a special user group used on some Unix systems to control access to the su command, which allows a user to masquerade as another user (usually the super user).

  • Uhm… on Berkeley Unix, wheel is just gid 0, but there’s no corresponding uid (well there is, it’s just root). This answer is wrong, but the question itself is… I’d say bad. I don’t get what he wants to ask.

  • @mirabilos I think the OP is asking about Linux. AFAIK most Linux distros have a root group with GID 0, and a separate wheel (or sometimes sudo) group that controls access to sudo.

  • Ah, I know of that as sudo group (on BSD, the wheel group indeed does both su and sudo). Thanks for clearing up.
