Before you begin the installation, make sure you have the following items:
-
VMware (ESXi 5.5 or later) installed and operational
-
Available hardware resources for the virtual machine. For more information, see OT monitoring with virtual appliances.
-
The OT sensor software downloaded from Defender for IoT in the Azure portal.
-
Traffic mirroring configured on your vSwitch. For more information, see Configure traffic mirroring with a ESXi vSwitch.
Make sure the hypervisor is running.
Note
There is no need to pre-install an operating system on the VM, the sensor installation includes the operating system image.
This procedure describes how to create a virtual machine by using ESXi.
To create the virtual machine using ESXi:
-
Sign in to the ESXi, choose the relevant datastore, and select Datastore Browser.
-
Select Upload, to upload the image, and select Close.
-
Navigate to VM, and then select Create/Register VM.
-
Select Create new virtual machine, and then select Next.
-
Add a sensor name, and select the following options:
-
Compatibility: <latest ESXi version>
-
Guest OS family: Linux
-
Guest OS version: Debian
-
-
Select Next.
-
Choose the relevant datastore and select Next.
-
Change the virtual hardware parameters according to the required architecture.
-
For CD/DVD Drive 1, select Datastore ISO file and choose the ISO file that you uploaded earlier.
-
In your VM options, change your boot options from Firmware to BIOS. Make sure that you're not booting from EFI.
-
Select Next > Finish.
-
To start installing the OT sensor software, open the virtual machine console.
The VM will start from the ISO image, and the language selection screen will appear.
-
Continue with the generic procedure for installing sensor software.
