Why is sudo considered safer than su?
sudo allows finer grain control. One can configure sudo to give root access to some but not all commands. sudo uses the login password. This protects having to give the root password (as you would with su) and is related to the point above regarding finer grained control / access to root.
Is sudo su dangerous?
It seems like allowing sudo su – poses a security risk by making access to the root account dependent upon individual user passwords. Of course, this might be mitigated by enforcing a strict password policy. I don’t think su – is any better since it would require the administrator to share the actual root password.
How do you sudo as root?
To use a “root” terminal, type “sudo -i” at the command line. The entire group of default graphical configuration tools in Kubuntu already uses sudo, so you will be prompted for your password if needed using kdesu, which is a graphical frontend to sudo.
Is it possible to run Sudo as another user?
You’re mixing sudo which allows running commands as another user and is highly configurable (you can selectively specify which user can run which command as which user) and su which switches to another user if you know the password (or are root). su always runs the shell written in /etc/passwd, even if su -c is used.
Why does the sudo command give root access?

Is it safe to use sudo with elevated privileges?
The sudo command is most often called like so. Many experts state that we should not work with elevated root privileges in a default manner. This is due to possible security and error related issues which can occur when using this elevated permission level.
Why do I get ” access denied ” when I Sudo Su?
I’m getting “access denied” attempting to login as root on the console and via ssh (Yes, I know root ssh access should be disabled – I’ve just inherited this box). I can login as non-root user who has sudo access to “ALL”, but when I sudo su – I get:
