Embedded software must be
contained in
programmed or one‐time‐
programmable read‐only
memory permanently
attached (non‐socketed) to a
circuit assembly.
O.SELECT
An explicit action by the
AUTHORIZED USER shall be
used to select the COMPUTER
to which the shared set of
PERIPHERAL DEVICES
CONNECTED. Single push
button, multiple push button,
or rotary selection methods
are used by most (if not all)
current market products.
Automatic switching based
on scanning shall not be used
as a selection mechanism.
O.SWITCH
All DEVICES in a SHARED
PERIPHERAL GROUP shall be
CONNECTED to at most one
SWITCHED COMPUTER at a
time.

EXT_ROM.1: implements the
O.ROM objective directly. While
there might be other ways to
protect embedded TSF code on
a ROM (programmable or not),
the requirement stipulates an
easily‐verifiable implementation
that ensures that the TSF code
will not be overwritten or
modified.
FMT_MSA.1: This restricts the
ability to change selected
PERIPHERAL
PORT GROUP IDS to the
AUTHORIZED
requirement is a dependency of
FMT_MSA.3.
FMT_MSA.3: The TOE assumes a
default
GROUP selection based on a
physical switch position or a
manufacturer's
sequence for choosing among
the CONNECTED COMPUTERS
(CONNECTED
powered on). This requirement
is a dependency of FDP_IFF.1a
and FDP_ITC.1.
FDP_IFF.1a: This requirement
identifies
ATTRIBUTES needed to detail
the operation of a switch and
the rules allowing information
transfer. This requirement is a
dependency of FDP_IFC.1a.
FMT_MSA.3: The TOE assumes a
default
