Ubuntu:: root password

I could not understand the policy of password for root user when I start to use Ubuntu linux.
I didn't know root password on Ubuntu Linux. Actually, no one know about it...... because it is null.

The policy of root password is that if root has no password then no one can attack it.
However, some one wont to use root as other distribution of linux. You can make password for root on Ubuntu Linux.
But, it makes risks for attacked by malicious user. Be careful to make your root password. If you want to make password for root then you should check your root password is safty or not by some kind of password checking site.

# sudo passwd root
enter password for current user (if your account has authority for using sudo command)
enter new password for root user
enter same password for root user
