Using sudo to replace su

Posted by Eric Lubow

Use sudo to execute commands as root as a replacement for su. In the /etc/sudoers file, add the following lines by using the visudo command:

Cmnd_Alias LPCMDS = /usr/sbin/lpc, /usr/bin/lprm
eric ALL=LPCMDS

Now the user 'eric' can sudo and use the lpc and lprm commands without having any other root level access.

Sudo Su

Can anyone tell me the difference beteen SUDO Su and using su to root with root password.
As I understand in the first case, when i do a Sudo su, i will have to use my own password and i baiscally become root without knowing root password.

Now the question is, what is the security implication in using both these mechanisms to access root
