Re: Home laptops on a corporate network

Just wondering...
But is it possible to setup a locked-down VMWare image for external
laptop users to use if they really-really need access your corporate
network. (a small subsection of the network inside its own DMZ
specifically designed to share data)


Personally, I can't think of a reason why an external laptop (or USB
drive for that matter) would need access to the internal corporate
network anyway. They can be provided with separate access to get onto
the internet from a segmented system that has no access to the
Internal system.

I wholeheartedly second that recommendation. Allowing corporate data on
private computers (or private computers on a corporate network) is a
bad, BAD practice. Never EVER do that. You really want to do the exact
opposite: establish a policy that *prohibit* employees from transferring
corporate data to private computers, and have it signed by each
employee.
