FDP_APC_EXT.1.1/AO The TSF shall route user data only from the interfaces selected by the user.
FDP_APC_EXT.1.2/AO The TSF shall ensure that no data or electrical signals flow between connected
FDP_APC_EXT.1.3/AO The TSF shall ensure that no data transits the TOE when the TOE is powered off.
FDP_APC_EXT.1.4/AO The TSF shall that no data transits the TOE when the TOE is in a failure state.
