A topic of concern in Linux

Yes, but if the cracker is trying to invade the system from the outside,
it doesn't matter if you are a big corporation or a home Linux network,
the userid is root, and the password is what the cracking software is
trying to brake. Now, if you set up the system to:
A. never allow login as root from the outside;
B. Change the userid root userid and group and everything associated
with it to something other then root;
you increase the security to the next level, and then the user verses
root thing applies.

One point that I forgot to mention about password security that can help
in decreasing the likelihood of it being infiltrated, is to change it
regularly. All OS's allow for a password timeout function, and when this
feature is used, you are automatically reminded to change your password.

OS security is a big thing throughout industry, and industry spends a
large amount of money on it. All I know that I can do on my part, is use
the guidelines set out by my employer on my home based system, and hope
that I have made my system secure enough. 

Simply put:
Just like locks, passwords, keep the honest out.
