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.

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.

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.

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.
