Answer: C
One risk of a VPN implementation is the chance of allowing
high-risk computers onto the enterprise's network. All
machines that are allowed onto the virtual network should be
subject to the same security policy. Home computers are
least subject to the corporate security policies and hence
are high-risk computers. Once a computer is hacked and
?owned?, any network that trusts that computer is at risk.
Implementation and adherence to corporate security policy is
easier when all computers on the network are on the
enterprise's campus. Internally to an enterprise's physical
network, there should be security policies in place to
detect and halt an outside attack that uses an internal
machine as a staging platform. Computers at the back up site
are subject to the corporate security policy. Hence, not
high-risk computers. Computers on the network that are at
the enterprise's remote offices, perhaps with different IS
and security employees who have different ideas about
security are more risky than choices A and B, but obviously
less risky than home computers.
