TD0539 clarifies that the mandatory selection (refined by the VI-Module) applies if the TOE fits the
Combiner Use Case selecting "multiple connected displays" in FDP_CDS_EXT.1.1. The TOE does not fit
the Combiner User Case but rather selects "multiple connected displays" because some models support
dual-displays from a single source video feed. Therefore, the selection does not apply.
The TSF shall resist [a physical attack for the purpose of gaining access to the
internal components, to damage the anti‐tamper battery, to drain or exhaust
the anti‐tamper battery] to the [TOE enclosure and any remote controllers] by
the attacked component becoming permanently disabled.
The TSF shall be able to provide reliable time stamps.
The TSF shall run a suite of self‐tests [during initial start‐up and at the conditions
[upon reset button activation]] to demonstrate the correct operation of [user
control functions and [active anti‐tamper functionality]].
The TSF shall provide authorized users with the capability to verify the integrity
of [TSF data].
The TSF shall provide authorized users with the capability to verify the integrity
of [TSF].
The TSF shall respond to a self‐test failure by providing users with a [visual]
indication of failure and by shutdown of normal TSF functions.
The TSF shall display a visible indication of the selected computers at all times
when the TOE is powered.
The TSF shall implement the visible indication using the following mechanism:
easily visible graphical and/or textual markings of each source video on the
display, [a button, a panel with lights].
The refined text: "easily visible graphical and/or textual markings of each
source video on the display", is added per the Video/Display Devices Module.
