Restricting logins

One of my systems needs to be restricted to a subset of people, but I
still want to use NIS. The system has 2 ways it may be accessed:
1. SSH - I set up AllowUsers and that works fine.
2. Console. Since we have a KVM, someone could log into the KVM and come
in through the console port. I can physically unplug the console, but I
was wondering if there was a way to accomplish this through an access lis=
I certainly can turn off NIS for this host and clone the password and
shadow entries, but I would prefer to allow NIS.

I'm not concerned about hackers outside of our VPN, but the contract for
the software we are working with specifically excludes anyone in our
development group. But, our IT people in NY do have a login.

In any case just looking for a suggestion.
