Appendix 3. Cybersecurity
This appendix is intended for the IT network responsible at the organization where the
displaying unit is used. It contains technical information regarding the setup of the IT
network and the devices connected to the displaying unit. It also contains information
regarding the types of data contained in and transmitted from the displaying unit.
The displaying unit is of medium security risk (according to NIST) as:
• The displaying unit does not allow any input from external devices (except from Ambu
visualization devices and secured software updates).
• Essential functionality is secured in case of network problems.
Appendix 3.1. Network Setup
When preparing the network for connection to the displaying unit, the following should
be considered:

Standards used Comments
IEEE 802.11 The device uses a WPA_Supplicant to support
WPA2 Wireless communication as TKIP and CCMP.
The authentication and integrity of the
communication is provided by the underlying
FIPS 140-2 compliant chipset wireless driver. Wi-Fi
option supports WPA2 Enterprise for mschapv2.
IEEE 802.3 The device uses a standard Gigabit Ethernet
IEEE 802.3ab controller supporting a 1000base-T interface.
IEEE 802.3az
PICMG3.1
ICMP/ping Allowing ease-of-discovery for hospital
IT infrastructure.
DHCP Static IP address (IPv4) is configurable in the GUI.
Static IP
The device does not support re-routing traffic
from Wi-Fi to LAN or vice versa, therefore the
device cannot act as a NAT (Network Address
Translation) gateway.
