I have a virtual machine running on Virtualbox on my host OS.
I want to make sure that my host PC is as safe from outside threats as possible. When using an ISO live image as the virtual machine, which of the following approaches to connect to the internet would you recommend:
and why?
Which would be the best way to connect to the internet while keeping the host computer not connected to the internet?
Pass through a physical adapter like usb-ethernet, wifi, PCI device (maybe not possible with virtual box).
Would I recommend using an iso live image? No. These live ISO images are always a bit behind and may be behind in security patches.
A USB adapter certainly separates the client network from the host network.
To further prevent the host from accessing the Internet, you could remove the default gateway. However, I would suggest that you keep your host and clients current, at least for security patches, and no access from the host to the Internet may complicate that.
