Hey Ryan,

The only other thing I could suggest is a dial-up callback system.
Windows NT 4.0 and above fully support this in their base installs, and
I'm sure it wouldn't be hard to setup on a FreeBSD network to do
something similar.  The way it works is this:

User requests login authority from their remote system.  He/she does so
with a username/password combination.

Remote network sees request, looks information up in a database and
either calls back via a dial-up connection, or replies only on an IP
address registered with the system.

This way, it is your network that is bringing the connection up.  It
also restricts where users can log in from.  (i.e. areas you, as network
admin, deem secure).

HTH

Just curious, what kinds of things are you trying to secure that the
basic password system hasn't worked for you?  Most users are too
ignorant (not their fault) to know how to do anything with their logins
to hurt anything, as if your system *is* secure enough, biometrics or
SecurID is a viable alternative.  I personally have done work for people
like the Minnesota Dept of Agriculture in this area for building and
network security, and it has worked wonderfully for the last 4 years.
Just curiousity on my part.  ;)

Hi Eric,

Yes. Bad idea. I knew someone would suggest that. My original post was
too long already to include biometrics, so, since you asked, here it
is. :-)

Depending on the metric somewhat, collecting biometrics on insecure
systems is a serious security risk. Hardware costs aside (about 20
terminals, a few of which are home systems not even owned by the
company), it's far too easy to replay biometrics if the end system
isn't secure... and, last time I checked, most of my employees had
only 10 fingers each. Once those are gone, what then? Eyeballs? :-)
So, on a lot of levels, biometrics are not an option.

So, let's stick with password security for now. :-)
