Introduction
Welcome to the documentation of the Industrial Edge Virtual Device (IEVD).
This is a virtual machine image based on the Linux Debian 11 (bullseye) distribution and the
Industrial Edge Device Kit Version 1.12.0-3, that we minimized and shaped for serving a
virtual Industrial Edge Runtime.
Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines and
networks. Systems, machines and components should only be connected to the enterprise
network or the internet if and to the extent necessary and with appropriate security measures
(e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
http://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

Introduction
Industrial Edge Virtual Device
5 Operating Manual, 03/2023
Security Measures
To fulfill "Security Guidelines for Device Builders" the following security measures were taken
during development of the Industrial Edge Virtual Device:
Network Segmentation
IEVD prohibits general routing or bridging between connected networks by default to prevent
it to operate as a bridge between two networks and therefore overrules existing subnet
segmentations that might ensure network security policies of the users' network operators.
Hard Reset
Whenever the hard reset is triggered, it is ensured that all security-relevant information is
deleted from the device to ensure that devices can be wiped for other use cases without
retrieving pre-existing information by the subsequent user.
Handling of Onboarding Credentials
Onboarding credentials are only transferred via secured connections and are not persistently
stored within the device to prevent intruders from catching files and gain access to devices or
IEM.
Time Synchronization
Time is synchronized with IEM after onboarding to ensure up-to-date information within the
device. Initial boot sequences get passed time via (virtual) RTC of the hardware.
Storage of Credentials
Credentials and certificates are stored in a secure manner as far as in scope of the device.
Secure Logging
Device emits logs via an API to be exported by IEM in case of auditing and operational
purposes.
Trusted Deployment of Updates
Updates are deployed and applied with the validation of integrity of the update package to
prevent the execution of malicious update images.
Authentication
There are no authentication mechanisms implemented by the device itself. User only
authenticates via Industrial Edge mechanisms.
Root privileges / Runtime protection
There is no authentication to the device given to the user and therefore no gain of root
privileges possible by accessing the device itself.
Miscellaneous
Due to the virtual execution of the IEVD a secured environment is assumed. Therefore, no
strong security measures in regards of physical intrusion are taken or may be achieved by the
user with hypervisor features (e.g., encryption).
In regard to intrusion from remote the device is secured and does not provide any remote
interfaces or open ports besides Industrial Edge platform dependencies.

FAQ
4
4.1 General
What is the IEVD for?
Whenever you want to use the Industrial Edge (IE) functionality without having a physical
Industrial Edge Device (IED), you can take into account the Industrial Edge Virtual Device
(IEVD).
What is different in IEVD from a "real" HW device?
The goal is to have the functional behavior as identical as possible. However some exceptions
could occur due to virtual nature of the IEVD.
4.2 Virtualization Platforms
Which virtualization platforms are supported?
VMware ESXi is the first supported virtualization platform currently (see Before we start
(Page 7) for more details).
Can I virtualize the IEVD on my laptop?
Yes. You can import and start it within VMware Workstation or Oracle VM VirtualBox (may
need some adjustments in VM configuration) in your local PC environment for non-
productive purposes as well.
My IEVD does not boot with "No bootable medium found!" in Oracle VM VirtualBox. How can I
boot?
By default the imported VM will not have EFI activated in Oracle VM VirtualBox. To make it
bootable you need to enable the "Activate EFI" option within the VM settings under "System".
FAQ
4.3 Connectivity
Industrial Edge Virtual Device
13 Operating Manual, 03/2023
4.3 Connectivity
How can I realize Layer 2 access through hypervisor?
If there is a vSwitch in place to handle connectivity between physical NIC and virtual NIC of
VM instance, the switch needs to be configured for "promiscuous mode" to allow L2 access if
required by Edge App.
Please note: Enabling promiscuous mode will expose your VM to every traffic within that
network.
Does IEVD support apps that require time-deterministic (Real-Time) behavior?
No. Ensuring of time-deterministic behavior would require special measures inside and
outside of IEVD. This has not been in scope of IEVD so far.
