<p>Apparatus and methods for facilitating secure data transfer, for use in off-site data backup, for example. A data port arrangement 2 is provided for inclusion on a source network 6 to transmit data received from a computing device 4 on the source network to a destination device 8 outside the source network via a router 28 on the source network and an external network communicatively coupled to the router, wherein the data is sent to the data port arrangement in a data packet including a destination address associated with the data port arrangement, the data port arrangement comprising: an input port configured to receive the data packet from the computing device on the source network; a data processing arrangement 18, 20, 22 configured to replace the destination address with the address of destination device and to encrypt the data to be sent to the destination device; and an output port configured to output the encrypted data for transmission to the destination device via the router and the external network. A destination network 10 for receiving encrypted data sent from such a data port arrangement is also described. The arrangement provides off-loaded encryption processing but also ensures that the router , which borders the public network (internet) does not handle unencrypted data.</p> |
