The root password is disabled by default so nobody can directly log into the root account.

However I can still log into root another way by doing `sudo su` and entering my own password, given that I am a member of the `sudo` group in `/etc/group` (as far as I know this is the only necessary condition).

Is this considered a bad practice to "backdoor" my way into the root account by using `sudo su`? Is it something to be avoided, and instead rely on using `sudo command` instead?
