Right, except "/etc/passwords" doesn't exist, and /etc/passwd doesn't
contain any password information in any Unix installation with a lick
of sense, and this brute force attack gets quite difficult if the users
are smart and they can use passwords > 8 characters (as is possible
with md5 passwords.) The user's encrypted password is stored in
/etc/shadow these days.

PAM can do a fair number of things. "man pam.conf" for info, though the
page is a bit dry/technical/complex.
Remember that no authentication system in the world will protect your
users if they insist on writing their passwords down on Post-It notes
and sticking those notes to their monitors, or making the passwords the
same as their usernames.
People don't tend to get paid.
