Canon Paper Shredder 3.3 FaxSecurity

3.3 – FaxSecurity

Canon imageRUNNER ADVANCEsystems that support Super G3 fax capabilitieswith the optional

Super G3 FaxBoard installed can be connected to the Public Switched Telephone Networkfor sending

and receiving offax data. In order to maintain the security of customer’s networks in relation to this

potentialinterface, Canon has designed its Super G3 Fax Boards to function in accordance with the

following securityconsiderations:

Super G3 FaxBoard Communication Mechanism

The modem on the Super G3 FaxBoards does not have Data Modem capability, but only Fax

Modem capability. Asa result, TCP/IP communication through the phone line is impossible.

In addition, there isno functional module such as a Remote Access Service thatenables

communication between a phone line and a networkconnection within the device.

FaxTransmission

The PCFax function can fax documents from the PC via Network, using a Fax driver thatruns

on the PC. However, data transfer from the PCvia Network to the device and data transfer

(FAXtransmission) from the phone line via the G3 FAX board is structurally separated.

FaxReceived

Although a received faxdocument can be accessed from the network through the Confidential

FaxMail Box function inherent in the device or automatically forwarded to a network, it is not

possible to breach the networkin either instance as these capabilities are afforded following

completion offacsimile communication. Since the data stored in the Confidential Fax MailBox

isin a format proprietary to Canon, there is no threat of virus infection. Even if the device

receivesa data file pretending to be a FAX image data but contains a virus, the received data

mustbe decoded first. While trying to decode the virus the phone line will be disconnected

with a decode error and the received data willbe discarded. The Super G3 Fax Boards cannot

receive data files, butare only capable of receiving and decoding facsimile transmissions.

Asa result, virus-laden files sent to an imageRUNNER ADVANCE system via itsphone line

connection cannotbe processed.

FaxPolling

FaxPolling is the only function that enables users to handle documents stored in a polling box.

Anyaction associated with these documents stored in a polling box is performed using G3 Fax

protocols, which provide no meansof accessing a local network.

FaxForwarding / Mailbox Fax Forwarding

The FaxForwarding function allows imageRUNNER ADVANCE systems equipped with a fax

board to forward inbound faxtransmissions to specific recipients. This is done bysetting

predetermined conditionsor storing faxes in a secure Memory Reception Inbox for later

printing rather than permitting incoming messagesto pile up in an open output tray.
