Objective
FDP_ETC.1 (Export of User
Data Without Security

FDP_IFC.1a (Subset
Information Flow Control)
FDP_IFC.1b (Subset
Information Flow Control ‐
Unidirectional Data Flow)
Rationale
FDP_ETC.1: In typical TOE
applications, USER data consists
of HUMAN INTERFACE DEVICE
control information.
included is configuration
information such as KEYBOARD
settings that must
reestablished each time the TOE
switches between COMPUTERS.
These DEVICES neither expect
nor require any
ATTRIBUTE information. The
information content of the data
passed through a CONNECTION
is ignored.
Note that although this SFR
appears in the
Protection Profile, it is not
applicable specifically for the
TOE as it does not handle
HUMAN INTERFACE
control information or states.
FDP_IFC.1a: This captures the
policy that no information flows
between different
PERIPHERAL PORT GROUP IDS.
FDP_IFC.1b: This captures the
policy that HUMAN INTERFACE
DEVICE data can flow only from
a device to a
COMPUTER, thus preventing
data from one COMPUTER
flowing through the TOE to
another COMPUTER.
