I'd say you'd be better off to restrict by login name rather than by
the tty.
If security is the issue then having a good password policy and
changing it after a set time frame is pretty good.
If people are still getting in and it's only a local network, then
education to the users who are accessing things they should be is
always a good step too.

Thanks,
