Pauline, please read the paragraph below. I have extracted from:
http://docs.hp.com/en/B2355-90950/apbs01.html"Q: Should Bastille disallow root logins from network tty's? [N] [N]
Level: Account Security
Bastille can restrict root from logging into a tty over the network.
This will force administrators to log in first as a non-root user, then
su to become root. Root logins will still be permitted on the console and
through services that do not use tty's ( e.g. HP-UX Secure Shell ).
This can stop an attacker who has only been able to steal the root password
from logging in directly to a tty. The attacker has to steal a second account's
password to make use of the root password via the network, or gain access to a
non-tty login mechanism.
MAKE SURE that you can login using a non-root account before you do this,
or you will obviously need access to the console or a non-tty remote login
mechanism, e.g. Secure Shell, to login."
