Re: stick a laptop to a LAN



Hi, Steven,
how could I be sure that the laptop will ONLY be able to connect to
our LAN and not any other.
Thanks for any help or hints.

well, there are many possibilities to achieve that. Just some thoughts:

1) my personal favorite (perhaps I'm a little bit prejudiced):
Install a HIPS like the Cisco Security Agent. There you can specify "Security-Conditions". For example: If the CSA-Management-Center is reachable and the PC is in your Network, then apply "normal" security. If the CSA-Management-Center is *not* reachable and the PC is in a different network, then apply a Network lockdown.


2) (I assume you are using Windows)
Configure a hardware-profile with disabled NIC and use this profile when you are abroad.


3) If someone "untrusted" is using the laptop you could plug a RJ45-Lock into the Ethernet-connector of the PC.


regards, Karsten Iwen
