1.4.2.2. Security Functions
The security functions provided by the TOE are the following.
(1) Hard Disk Data Overwrite
To completely delete the used document data in the internal HDD, the data are overwritten with
new data after each job (copy, print, scan, Network Scan, Fax, or Direct Fax) is completed.
Without this function, the used document data remain and only the management data are deleted.
(2) Hard Disk Data Encryption
Some data such as the security audit log data and the document data in Mailbox remain in the
internal HDD even if the machine is powered off. To solve this problem, the document data and
security audit log data are encrypted before being stored into the internal HDD when operating
any function of copy, print, scan, network scan, fax, and Direct Fax (with local authentication
only), or configuring various security function settings.
(3) User Authentication
Access to the TOE functions is restricted to the authorized user.
A user needs to enter his/her ID and password from the fax driver, Network Scan Utility, or Web
browser of the general user client, or MFD control panel. A user can also use Smart Card
authentication on the control panel.
Only the identified and authenticated user can use the following functions:
a) Functions controlled by the MFD control panel:
Copy, fax (send), scan, network scan, Mailbox, and print (This print function requires the
Accounting System preset from printer driver. A user must be authenticated from the control
panel for print job.)
b) Functions controlled by Network Scan Utility of user client(with local authentication only):
Function to retrieve document data from Mailbox
c) Functions controlled by Configuration Web Tool:
Display of device condition, display of job status and its log, function to retrieve document data
from Mailbox, and print function by file designation
Among the above functions which require user authentication, some particularly act as security
functions. The following are the security functions which prevent the unauthorized reading of
document data in the internal HDD by an attacker who is impersonating an authorized user:
・ The Store Print function (Private Print function) and the Mailbox function, which require user
authentication from the control panel or Smart Card.
・ The function to retrieve document data from Mailbox (Mailbox function) which requires user
authentication by using Configuration Web Tool or Network Scan Utility (with local
authentication only), and the Store Print function (Private Print function) by file designation
using Configuration Web Tool.
