FDP_ITC.1
(Import

User
Data
Without
Security
Attributes)
This
requirement
identifies
the
security
ATTRIBUTES
needed
to
detail
the
operation
of
a
switch
and
the
rules
allowing
information
transfer.
This
requirement
is
a
dependency
of
FDP_IFC.1a.
FDP_IFF.1b:
This
requirement
identifies
the
security
ATTRIBUTES
needed
to
detail
the
operation
of
a
switch
and
the
rules
allowing
only
unidirectional
information
transfer
between
a
keyboard,
pointing
device
and
EDID
chip
to
a
CONNECTED
COMPUTER.
Unidirectional
peripheral
data
flow
is
critical
to
assure
that
data
confidentiality
is
maintained
as
it
prevents
data
from
entering
the
TOE
from
one
COMPUTER
and
exiting
the
TOE
to
another
COMPUTER.
This
requirement
is
a
dependency
of
FDP_IFC.1b.
FDP_ITC.1:
In
typical
TOE
applications,
USER
data
consists
of
HUMAN
INTERFACE
DEVICE
control
information.
These
DEVICES
neither
expect
nor
require
any
security
ATTRIBUTE
information.

shall
receive
an
unambiguous

EXT_VIR.1
(Visual
Indication
Rule)
EXT_VIR.1:
There
must
be
some
positive
feedback
from
the
TOE
to
the
USER
to
indicate
which
SWITCHED
COMPUTER
is
currently
CONNECTED.
