Page 61 of 82 O.GENUINE Protection of integrity of MFP Control Software integrity Following are the rationale behind the functional requirements corresponding to O.GENUINE in Table 23, 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 shall be verified. For this, FPT_TST.1 tests the integrity of the executable code of the MFP Control Software, 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 23, 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. 6.3.3 Dependency Analysis Table 24 shows the correspondence of dependencies in this ST for the TOE security functional requirements.
