Yes, it is entirely possible that they have implemented some security measures to help protect those systems. I'm sure that there is a firewall of some sort involved and also probably also some local client security solution in place. That still doesn't mean that allowing access is a secure action.

Consider a similar situation. Boeing is claiming that they can have the same wiring in the 787 carry both flight control data and IFE communication. Even with "security" solutions in play no one in their right mind would agree that it is a secure implementation.

The real question is whether those computers are or should be considered secure. Considering the access that I assume they have to the passport data, I would hope that they are secure. If they are, they should be isolated.
