The
TOE
design
provides
clear
and
continuous
visual
indication
of
the
selected
channel
through
one
or
more
of
the
following
(model
specific):
front
panel
LEDs
illuminated
for
each
channel
number
selected,
DCU
display
text
highlighting,
and
windows
frame
colors
(in
Windowing
KVM
models).
The
PERIPHERAL
PORT
GROUP
is
connected
to
COMPUTER
#1
by
default
upon
completion
of
the
self
‐
check.
This
static
setting
cannot
be
modified.

Protection
of
the
TSF
(TSF_TMP)
The
TOE
includes
multiple
tamper
sensors
connected
to
a
microcontroller.
When
a
sensor
is
activated,
it
signals
the
microcontroller
to
enter
into
a
permanent
tamper
state,
thereby
disabling
the
TOE
normal
functionality
permanently.
The
tampering
sensors
and
microcontroller
are
powered
by
the
TOE
power
system
while
the
TOE
is
powered
on.
When
TOE
is
powered
off,
the
anti
‐
tampering
subsystem
is
powered
by
a
coin
battery
to
enable
operation
while
the
TOE
is
in
transit
or
in
storage.
After
a
tampering
event
is
detected,
all
LEDs
flash
to
indicate
an
error
state.
While
the
TOE
is
in
the
error
state,
the
user
is
unable
to
pass
any
information
through
the
TOE
to
any
COMPUTER,
and
user
DISPLAYS
are
blank.
Since
the
TOE
becomes
unusable,
the
user
will
require
replacement
of
the
TOE.
This
ensures
that
security
is
always
maintained
in
the
event
of
a
physical
attack.
The
TOE
is
also
protected
by
special
holographic
Tampering
Evident
Labels
that
are
used
as
seals
to
provide
additional
visual
indication
of
attempted
physical
tampering.
In
the
case
of
a
mechanical
intrusion
attempt,
the
label’s
location
between
enclosure
parts
assures
that
the
label
must
be
moved
or
peeled,
permanently
exposing
the
text
“VOID”.
Each
Tampering
Evident
Label
contains
a
unique
identification
number
and
several
visible
and
invisible
means
to
assist
the
operator
in
checking
the
authenticity
of
the
label.

USB
Connection
(TSF_IUC)
When
a
peripheral
device
is
connected
to
the
TOE,
or
when
the
TOE
is
being
initialized,
the
TOE
will
query
the
device
for
its
characteristics
such
as
USB
class,
sub
‐
class
etc.
In
the
event
that
the
reported
set
of
characteristics
match
the
pre
‐
defined
profile,
the
TOE
will
start
communicating
with
that
device
(device
is
QUALIFIED).
In
the
event
that
the
device
reported
characteristics
do
not
match
the
pre
‐
defined
profile,
the
TOE
will
reject
the
device
and
will
no
longer
communicate
with
it
(device
is
rejected
or
UNAUTHORIZED).
