O.GENUINE Protection of integrity of MFP Control Software integrity
Following are the rationale behind the functional requirements corresponding to O.GENUINE in Table 22,
and these requirements are included to fulfil the O.GENUINE specification.
a) Check the integrity of the MFP Control Software.
To fulfil O.GENUINE, the integrity of the MFP Control Software, which is installed in FlashROM,
shall be verified. For this, FPT_TST.1 tests the integrity of the executable code of the MFP Control
Software, which is installed in the FlashROM, and verifies its integrity at TOE start-up.
O.LINE_PROTECT Protection from intrusion via telephone line
Following are the rationale behind the functional requirements corresponding to O.LINE.PROTECT in Table
22, and these requirements are included to fulfil the O.LINE.PROTECT specification.
a) Prohibit intrusion via the fax line.
To fulfil O.LINE_PROTECT, unauthorised access by an attacker to the TOE via telephone line shall be
prevented.
For this, FDP_IFC.1 and FDP_IFF.1 allow fax data to pass from the fax process on the Fax Unit to the
fax reception process on the Controller Board only if the data received from the telephone line is fax
data.
