Our network engineer proposed ATM PVC's as a means to route Internet traffic across our corporate backbone. Obviously, the best approach is to carry the Internet traffic on totally separate channels. However, we have to distribute Internet access to far flung sites on our corporate owned network, and network engineering does not want to pay for independent communication channels. They insist on using the existing corporate network infrastructure because it is already there. I proposed VPN's as more secure than PVCs. Any other alternatives? I am looking for feedback on using PVC's versus VPN's as a security barrier between our corporate network and the Internet. Note I am proposing that VPN's provide security in the reverse direction than how they are typically used. Rather than protecting traffic inside the VPN transversing an insecure network, I am proposing that a VPN can protect a corporate network from the insecure Internet traffic confined within the VPN. Is this a valid assumption? Note: both ends of the VPN terminate at a firewall that we control. Comments?
