I've been asked this.
At an organisation there are two networks.  One that is for confidential information and the other is used to demonstrate things to customers.  Both use RJ45 connections and the routers for each are next to one another in a room that all staff have a key to.  Each office will have sockets on the wall with both networks exposed.

Now the question is this:  How simple would it be for someone to connect things such that  the confidential network is exposed to the open network?

the thing is not clear what kind of network you have... speciallt aout the confidential information is having in the network... as you said..

if it's domain based ... then no need to worry... even if they cinnect to lan i.e network port.. they'll not get any thing...  untill unless they'll get authenticate to acces resources on the network by Authentication server ( Mostly Domain Controller)

there are many thing will comes in to the picture when you plug a PC or laptop to a network,

the technical way...

there is 3 way handshake happens when the comunication starts...

see the article

http://support.microsoft.com/kb/172983

so if the proper network is ther then no need to worry...


 if it's work group network .. not a domain network ... then you have to worry about the shared folder which are having permission for every one... are can be visible to any one...

that's it...


i hope you get understand it...

Thanks.
Domain network.
I thought it wouldn't be simple, I just wanted to confirm that as I'm not an expert with networking.

I'll leave the question open for a while just in case someone knows differently.

Domain network for the confidential one, the other I'm not certain about.

Just an idle thought.
Could someone have two network cards in one PC, connect one to each network - would that then create a problem ?

OK go ahead...


the domain network is Centralised and the Authentication is through the Domain... and the sharing and security permission will also as per domain norms and sharing will access only wiht domain clients and in case out sider want to access the shared files .. .if they have to provide domain authenticated Username and pawword

any how you can google for more...
