6.3.3. Security Assurance Requirements Rationale
This TOE is for a MFD, a commercial product. The following threats are assumed to be caused by a
low-level attacker: attack or interception/alteration of data on internal network via a MFD external
interface from control panel, Web browser of system administrator’s client; and reading-out of
information by removing the internal HDD and connecting it to a commercial tool.
To counter these threats, this TOE is required to provide the security functions which assure security.
The evaluation assurance level of the TOE is EAL3 which includes the following analyses:
- Analysis of the security measures of the TOE at development phase
(Performing/analyzing systematic tests and evaluating the management of the development
environment and the developed products.)
- Analysis of whether the sufficient guidance information is included so that the security functions can
be used safely.
Therefore, EAL 3 is the reasonable evaluation level for this TOE.
