are successfully identified and authenticated. It prevents the HDD1 and HDD2 from the
unauthorized access.
Therefore, OE.HDD can be realized by the correspondent security functional requirements.
8.2.1.3. Adequateness for supporting of security functional requirements - FDP_MTD.1 and
FDP_SOS.1 by assurance requirement
FDP_MTD.1 executes only changing “TSF data” of FMT_MTD.1 to “administrator data” and
means the same as FMT_MTD.1 “control the security function”. FDP_SOS.1 executes only
changing “secret” of FIA_SOS.1 to “secret for IT environment” and means the same as FIA_SOS.1
“validation of secret”.
Therefore, they can apply to the same assurance requirement with FMT_MTD.1 and FIA_SOS.1,
namely the present assurance requirement.
