Follow up to ATM and VPN's

[Fullerton, Glenn]

The question you have to ask

is a PVC on ATM secure enough without encryption.. your call.  There are to
many variables and opinions and business models to generally answer that.

VPN is by definition has encryption associated with it.  So people use VPN
to equal some level of encryption.  Same as users equate a Xerox machine for
a photocopier.

So if we leave the word VPN out.  Is data secure enough for your company to
allow it to flow from point A to point B unencrypted.

If you already have to maintain the expense of a real private network
(instead of a virtual one) for other reasons, such as performance or
availability, your statement is correct.

In many situations, the level of service that your ISP provides for external
e-mail and web access is just fine for the rest of your organization's data
that has to travel wide-area links, and for these situations VPN technology
was invented.
