You need to look into something like Network Quarantine.

Dear all,

Is it possible to filter unknown device to attach network?

Our network is connected with variety sites by Optical Fiber and VPN. In some locations, there is unable to know user's behavior. I found that some unknown devices are pluged into the network. I guess it could be the portable machine ,that is owned by those remote users, and plug into the network with some reasons....

It is REALLY a security issue!

1.) Those machines can be used to steal our protected data as well as how many the user can reach. Even I have protected the network by restrict all workstations with user right, software restriction policy and disable USB device but it is still unable to protect from this vulnerability.

2.) If it is driven into worst most circumstance as those portable machine are infected with network worm and our workstations/servers are not updated with the latest patch, the result could be absolutely unpredictable!

So, I wanna a solution to filter all unknown device to plug into our network. Is it possible?

Thanks,
Keith
