Title: NETWORK SCANNING SYSTEM
Abstract:
A method for scanning a local network from a remote infrastructure comprises setting up a VPN connection between the two, using an entity on the local network. The remote infrastructure uses network address translation (NAT) to direct incoming traffic from the entity to a scanning engine on the remote infrastructure. The entity also carries out NAT to change the apparent source of scan packet data coming from the scan engine to that of the entity, and to further use NAT to change the apparent destination of responses from the target computer from that of the entity to that of the scan engine. Embodiments of the invention therefore provide a method for scanning a network that allows a scanning engine to scan a local network from a remote infrastructure, but with the scanning engine effectively being part of, via the VPN and the use of NAT, the local network. The scan will typically be a security scan.
