3. SECURITY PROBLEM DEFINITION
This chapter describes the threats, organizational security policies, and the assumptions for the use of
this TOE.
3.1. Threats
3.1.1. Assets Protected by TOE
This TOE protects the following assets (Figure 5):
(1) Right to use MFD functions
The general user’s right to use each function of the TOE is assumed as an asset to be protected.
(2) Document data stored for job processing
When a general user uses MFD functions of copy, print, fax, and scan, the document data are
temporarily stored in the internal HDD for image processing, transmission, and Store Print. The
user can retrieve the stored document data in the MFD from a general user client by
Configuration Web Tool and Network Scan Utility (with local authentication only). The stored
data include general user’s confidential information and are assumed as assets to be protected.
(3) Used document data
When a general user uses MFD functions of copy, print, fax, and scan, the document data are
temporarily stored in the internal HDD for image processing, transmission, and Store Print. When
the jobs are completed or canceled, only the management information is deleted but the data itself
remains. The residual data include general user’s confidential information and are assumed as
assets to be protected.
(4) Security audit log data
In the function of Security Audit Log, the important events such as device failure, configuration
change and user operation are recorded based on when and who operated what function. For
preventive maintenance and response to the events and detection of unauthorized access, only a
system administrator can retrieve the log data stored in MFD by Configuration Web Tool.
The log data are assumed as assets to be protected.
(5) TOE setting data
A system administrator can set TOE security functions from the MFD control panel or system
administrator client by the function of System Administrator’s Security Management. The setting
data stored in the TOE (see Table 4) can be a threat to other assets if used without authorization
and are assumed as assets to be protected.
