What's a good way to make a Debian VM reasonably safe for online banking if running Windows as a host system?

I thought of the following points:

  • normal usage of the Windows system as a restricted user X (I think its called "User" in Windows)
  • Setup and Run secure VM by starting Virtual Box as another restricted user Y
  • Allow write access of secure VM storage file only as user Y
  • run reasonably secure browser setup in vm (no javascript, no flash)

Does that sound good and what would you suggest to do further?

    What are you trying to protect against? Malware accessing your account? In theory, the host system could have a keylogger running which grabs your username and password, even if entered in a VM. Network attackers? The data is still going out in the same way. People with access to your physical machine? In short, what does it have to be safe from? – Matthew Dec 23 '16 at 15:51
  • Additionally, disabling flash and JS isn't ever a workable solution - most bank sites use it for virtual keyboards, image views etc. But more importantly, as @Matthew said, what are you trying to protect from? – thel3l Dec 23 '16 at 16:03
  • Also use a vpn and always ensure a strong https connection. – d1str0 Dec 23 '16 at 17:32

The VM is only as secure as the machine it's running on.

The proper setup is a clean install from verified media, and then doing all untrusted, day-to day activity in a VM. And secure business in another, clean VM

That way you have an installed machine. For simple things, just make a linux live USB and work from that.

  • How is "Do risky stuff in a VM" not a VM solution? Then the banking could be done on the host as well, at least you get some added security. – J.A.K. Jan 24 '17 at 22:26
  • Doing risky stuff in a VM is absolutely the right solution. Your previous answer, before you just edited it, said "Boot from a Linux Live USB stick", which is not what was being asked for. – John Deters Jan 24 '17 at 22:35
  • I moved it to the bottom; you're right my recommendation did not strictly match the answer. So i made it the secondary option, however my original post did answer the question. Just not in the first sentence. – J.A.K. Jan 24 '17 at 22:38
