Hello, I have a droplet with CentOS 7 and Plesk installed from marketplace. I have also followed the initial CentOS 7 server setup and disabled root access from ssh.
But for users that have access to their Plesk accounts, they can su root and that will prompt a password.
Is there a way to block this su command for only a specific high privilege user as the one created on the initial server setup?
Is there something else to add security to the server?
Thank you.

Hi @danielpcharrua,
This is something that can’t be avoided. What I can think of is the sudoers file - /etc/sudoders which grants/takes away privileges for commands however executing ‘su root’ isn’t one of them I think/
In such a case, what I’ll recommend for security would be to jailshell the user’s SSH sessions, that should be enough.
