Using sudo to replace su
Posted by Eric Lubow   
Security Tips 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
Now the user 'eric' can sudo and use the lpc and lprm commands without having any other root level access.

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
